Chapter Summaries

Summary

Key Plot Points and Events

• Gu Heng skips Class D’s first proposal meeting and instructs Horikita not to wait for his explanation unless he personally confirms one.
• Horikita forces the class to review each exchange detail individually, making the meeting slower but shifting responsibility away from dependence on Gu Heng.
• Sudo argues for assigning strength-based events to the strongest students, while Hirata prioritizes checking everyone’s training limits. Their disagreement is recorded neutrally rather than treated as sabotage.
• Kushida suggests giving unused exchange permissions to whoever can make the class feel most comfortable, implicitly positioning herself or another trusted figure. Horikita rejects this, arguing that reassurance does not equal authority without someone accepting responsibility.
• Gu Heng consults the school about submission rules. Chabashira-sensei confirms that the deadline will not pause during his absence and questions whether Class D can function without him.
• When Gu Heng returns, the class has completed an initial personal review: eight students confirm participation in second-round groups, three reject long-distance events, two reject temporary exchanges, and one accepts a final backup role. The unused permissions remain unassigned.
• Horikita presents Gu Heng with his own confirmation page, requiring him to choose between being the sole submitter or serving as a reviewer.
• Gu Heng refuses sole submission authority, recognizing that doing so would fulfill Ryuuen’s demand for centralized dependence. He confirms his choice to become a reviewer instead.
• His decision creates a vacancy that must be filled before noon. Horikita immediately begins screening candidates, requiring each person to review the representative’s authority, deadline, and refusal conditions.
• Hirata agrees to act as temporary recorder but refuses to become representative, explaining that he can document others’ decisions but cannot make decisions for them.
• Kushida abandons her earlier attempt to push a unified recommendation and instead asks openly whether the class is willing to lose the submission opportunity if no one accepts responsibility.
• By the end, the representative role is no longer treated as Gu Heng’s position waiting to be restored; it becomes an active responsibility another class member must consciously accept.

Character Developments

• Gu Heng: Moves from demanding personal confirmation from others to applying the same standard to himself. By refusing sole submission authority, he accepts a less dominant role and breaks his pattern of centralizing control.
• Horikita: Demonstrates growing independence and organizational authority. She keeps the meeting functioning without Gu Heng, rejects vague appeals to goodwill, and turns the representative vacancy into a structured selection process.
• Hirata: Shows self-awareness by distinguishing between recording consensus and making decisions for others. His refusal is framed as a principled limitation rather than cowardice.
• Kushida: Briefly attempts to convert popularity and emotional reassurance into authority, but Horikita stops her. Later, she shifts toward a more honest, open question instead of manipulating the class toward a “unified” opinion.
• Sudo: Represents the practical, strength-oriented approach to event assignments.
• Ayanokoji: Quietly recognizes the importance of Gu Heng being forced to record his own position, highlighting the chapter’s emphasis on accountability.
• Ryuuen: Observes Gu Heng’s refusal and hesitates, suggesting that Gu Heng’s choice disrupts the arrangement or leverage Ryuuen expected.

Significant Themes

• Responsibility versus authority: Authority cannot simply be inherited or assumed; it must be personally confirmed and accepted.
• Dependence and decentralization: Class D is tested on whether it can function without its dominant organizer.
• Personal confirmation: Every decision, including refusal, must belong to the individual making it rather than being hidden behind class consensus.
• Accountability and self-application: Gu Heng is forced to follow the same standards he imposed on others.
• Consensus versus coercion: Disagreement is recorded as legitimate disagreement, not automatically labeled betrayal or sabotage.
• Leadership as burden: Representation involves irreversible consequences, deadlines, and the duty to decide when consensus fails.

Character Interactions

• Horikita challenges both the class’s dependence on Gu Heng and Kushida’s attempt to equate comfort with authority.
• Sudo and Hirata clash over whether event assignments should prioritize ability or individual limits, but their disagreement remains constructive.
• Gu Heng and Horikita confront each other over whether he will retain sole submission power; he ultimately accepts her demand for personal accountability.
• Ayanokoji’s quiet observation reinforces Gu Heng’s realization that he, too, must be included in the system of confirmation.
• Hirata and Horikita cooperate in different roles, with Hirata documenting the process while Horikita manages authority and responsibility.
• Kushida’s interaction with Horikita marks a shift in their power dynamic: Horikita prevents Kushida from shaping the class through indirect emotional influence.

Chapter Summary: “Horikita Was Not a Stand-In”

Key Plot Points and Events

• After Gu Heng refuses sole submission authority, Class D’s representative position is left vacant. Hirata declines, admitting he can coordinate the class but does not want to make decisions without consensus.
• Horikita volunteers and becomes the official representative. A new two-tier structure is established:
  • Horikita: submits the class plan and makes final decisions.
  • Gu Heng: reviews sources, schedules, and rule compliance but cannot revise or submit directly.
  • Hirata: confirms that members have completed their personal reviews.
• Ayanokoji remains unofficial, observing the other classes without becoming part of the formal procedure.
• Ryuuen publicly challenges Horikita’s independence, suggesting she is merely Gu Heng’s nominal representative. Horikita responds personally by publishing her confirmation records and declaring that she will accept only verifiable advice and reject unsupported suggestions.
• The school recognizes Horikita as an independent submitter, restricting Gu Heng’s authority to document verification.
• During the first plan submission, Horikita uses the confirmations of eight classmates to organize the relay, long-distance event, and backup assignments. A proposed arrangement requiring Temporary Exchange Authority is removed because it lacks sufficient confirmation, even though this disadvantages one student.
• Gu Heng identifies a timing contradiction involving Sudo’s withdrawal from a responsibility. Rather than changing the record himself, he points out the inconsistency. Horikita insists that Sudo’s earlier verbal intention cannot count as an official action, delaying submission by seven minutes but preserving procedural accuracy.
• Class D’s first plan is accepted. Ryuuen observes that Gu Heng can still influence plans despite no longer submitting them, while Sakayanagi notes that Horikita is gaining the authority to reject him.
• Kushida later delivers an unsigned note asking who will record Gu Heng’s worst possible outcome after he stops submitting. Gu Heng documents the physical delivery but refuses to attribute authorship without proof.
• Horikita orders the note excluded from the official plan but preserved in the risk file, establishing that uncertain evidence should be retained for comparison without being treated as an accusation.

Character Developments

• Horikita takes genuine leadership for the first time. She proves she is not merely acting on Gu Heng’s behalf and accepts responsibility for rejecting both unsupported class suggestions and Gu Heng’s own opinions.
• Gu Heng deliberately relinquishes operational authority and adapts to a review role. He demonstrates procedural discipline by identifying contradictions without altering records and by separating confirmed facts from speculation.
• Hirata remains a stabilizing coordinator, supporting the process without claiming decision-making authority.
• Ayanokoji continues to operate independently, observing rather than participating formally.
• Sudo learns that verbal intentions do not count as official commitments unless properly recorded.
• Kushida introduces a suspicious, ambiguous warning while carefully avoiding responsibility for its authorship, suggesting continued manipulation or hidden motives.
• Ryuuen and Sakayanagi recognize that Horikita’s authority is becoming independent and that Gu Heng’s influence has changed rather than disappeared.

Significant Themes

• Authority versus influence: Gu Heng loses the power to submit directly but can still affect decisions through review and advice.
• Independent leadership: Horikita’s role becomes legitimate only when she can disagree with and reject Gu Heng.
• Evidence and accountability: The class distinguishes between verified records, verbal statements, anonymous material, and unsupported claims.
• Transparency and due process: Even inconvenient or potentially damaging information is preserved, but it cannot create consequences without proof.
• Responsibility through consent: Personal confirmation determines whether an individual commitment can bind someone, preventing the class from assigning responsibility without explicit agreement.
• The cost of structural reform: Horikita gains visibility and authority, while Gu Heng loses direct control.

Character Interactions

• Horikita and Gu Heng establish a more equal relationship: she acknowledges that he gave up his position but refuses to preserve it for him.
• Horikita publicly defends her independence against Ryuuen’s accusation instead of allowing Gu Heng to respond.
• Gu Heng and Hirata cooperate within clearly separated roles, with Hirata confirming completion and Gu Heng checking procedural accuracy.
• Gu Heng corrects Sudo’s record indirectly, allowing Sudo to admit the mistake himself while Horikita enforces the official standard.
• Horikita and Gu Heng jointly handle Kushida’s anonymous note, combining his evidence-preservation with her decision about how the class should use it.
• The chapter ultimately shows Class D shifting from personality-based authority to a system based on confirmation, documentation, and clearly separated responsibilities.

Chapter Summary: “Sources on Paper”

1. Key Plot Points and Events

• Gu Heng receives an anonymous paper accusing or warning about an unspecified matter, but refuses to hand it to Horikita or confront Kushida without verifying its source.
• Using the Source Verification Field, the class determines that the paper was printed on Class D’s public printer. Yukimura finds four print jobs, two of which came from unidentified terminals, making it impossible to prove who printed it.
• Gu Heng establishes a rule through Hirata: anonymous information may be retained, but no conclusions can enter the class proposal without a verifiable source.
• Kushida challenges this policy, but Gu Heng refuses to treat her statements as reliable without evidence. Her reactions suggest she is probing for weaknesses and preserving an escape route.
• Kushida submits a second document containing a time, print number, and screenshot proving that information originated from a Class B terminal. The information claims that someone in Class B considered having Class D approve a plan first and sign later, violating existing rules.
• Gu Heng places this information in Pending Verification rather than immediately using it in the proposal. He also records Kushida’s source in the Cold Backup, limiting its use to public-rule verification and keeping her personal information inaccessible.
• Class D sends Class B a neutral verification request rather than making an accusation. Ichinose confirms that the improper idea had been discussed but cannot guarantee it has entirely disappeared. She offers to provide the time of withdrawal in exchange for having her external dealings recorded.
• The second proposal exchange approaches, with Class B’s possible rule violation viewed as potentially more dangerous than Ryuuen’s direct provocation.

2. Character Developments

• Gu Heng reinforces his role as a cautious information controller. He separates evidence from conclusions, refuses to reward unverified claims, and creates formal records of responsibility.
• Kushida shifts from indirect manipulation to providing traceable evidence. Although she remains secretive and does not fully reveal her motives, leaving behind verifiable documentation marks a limited change in how she interacts with Gu Heng.
• Yukimura functions as the class’s verification specialist, checking printer records and preserving evidence in the Cold Backup.
• Horikita supports a procedural, non-accusatory approach by insisting that Class B’s claim be verified before Class D changes its proposal.
• Hirata continues serving as the public communicator for Gu Heng’s rules and information policies.
• Ichinose demonstrates responsibility by acknowledging Class B’s internal discussion and offering additional information, though her inability to guarantee her entire class’s compliance shows the limits of her authority.
• Ayanokoji recognizes that Kushida has not disclosed everything, but accepts that her next move must be observed rather than assumed.

3. Significant Themes

• Verification versus suspicion: The chapter emphasizes that even accurate warnings cannot be treated as established facts without evidence.
• Responsibility and traceability: Gu Heng requires people to attach their names, sources, or records to claims, making accountability more important than persuasion.
• Controlled trust: Kushida’s information is neither accepted blindly nor rejected outright; it is stored and restricted according to what can be verified.
• Information as power: Whoever controls the movement of evidence can influence the class’s decisions, while anonymous information remains dangerous precisely because it cannot be assigned responsibility.
• Leadership and independence: Kushida observes that Gu Heng’s withdrawal from sole control causes others to act independently, testing whether the class can function without relying entirely on him.
• Diplomacy over confrontation: Horikita and Gu Heng choose a neutral inquiry toward Class B, seeking clarification without escalating tensions.

4. Character Interactions

• Gu Heng and Kushida engage in a tense exchange over trust, evidence, and responsibility. He refuses to be drawn into emotional reassurance, while she tests whether her information will be accepted.
• Kushida’s brief remark that Gu Heng is “annoying” reveals frustration at his refusal to let her control the narrative, but her decision to leave traceable evidence behind changes the practical terms of their relationship.
• Hirata publicly communicates Gu Heng’s verification policy, reinforcing Gu Heng’s authority without making him the sole visible decision-maker.
• Ayanokoji and Gu Heng discuss Kushida’s omissions, agreeing that uncertainty should be observed rather than converted into unsupported conclusions.
• Horikita and Ichinose establish a cautious diplomatic channel between Classes D and B, creating a new issue for the exchange: whether individuals will accept personal accountability to correct a potentially damaging proposal.

Chapter Summary: “Kindness Must Pay Its Own Bill”

Key Plot Points and Events

• Ichinose privately approaches Class D before the second exchange round, bringing evidence that a Class B member had improperly proposed confirming Class D’s bearer in advance.
• She explains that she made the member withdraw the proposal rather than erasing the personal record. Her goal is to prevent one person’s mistake from being treated as proof that all of Class B supports such behavior.
• Class B and Class D complete a limited, carefully defined exchange:
  • Class B provides the withdrawal time and personal statement concerning the improper proposal.
  • Class D provides its public record of used Exchange Privileges.
  • Personal names and unverified accusations are excluded.
• Class B members criticize Ichinose for exposing internal problems to Class D. She accepts responsibility by adding her own confirmation to the record and clarifying that the delivery reflects her decision, not a guarantee from the entire class.
• Class B representatives demand that she cancel the exchange. Ichinose refuses, recognizing that withdrawal would delay Class D’s review of the rules. Instead, she accepts a new internal restriction requiring two witnesses for future external exchanges.
• Ryuuen notices the evidence exchanged between Class B and Class D and exploits it. Class C offers a competitor for the Strength Event only if Class D reveals the source of Ichinose’s information.
• Horikita and Gu Heng recognize that Ryuuen is attempting to make Class D pay for Class B’s internal conflict and test whether it will sacrifice Ichinose’s privacy for an event advantage.
• Class D initially refuses the demand. Sudo confirms that the class can participate without relying on Ryuuen’s competitor.
• Gu Heng publicly records both consequences: accepting would secure a competitor but expose Class B’s source; refusing would protect the source but leave Class D disadvantaged.
• Horikita requires every Class D student to review the decision personally rather than allowing Gu Heng to bear responsibility for the entire class.
• A Class D member suggests asking Ichinose directly to reveal the source. Gu Heng permits a request but insists that she must be free to refuse and that her refusal cannot become a debt.
• The request is reformulated as a formal Public Inquiry. Ichinose does not immediately agree, saying she will decide after reviewing it herself.
• Ryuuen then escalates the conflict, shifting from class-level conditions to personal demands by asking Class D to trade a specific individual’s name for a guaranteed event position.

Character Developments

• Ichinose demonstrates that her kindness is not passive: she is willing to accept blame, suspicion, and restrictions in order to prevent a small wrongdoing from damaging Class B’s reputation. Her decision shows a growing willingness to treat goodwill as a personal responsibility rather than something she can simply offer without cost.
• Gu Heng becomes more ethically conscious in his leadership. Instead of focusing only on the optimal strategic outcome, he records the real costs of each decision and protects Ichinose from being treated as an exploitable resource.
• Horikita reinforces collective responsibility by requiring Class D members to examine and approve the choice themselves. She also recognizes Ichinose’s development and the burden she is beginning to carry.
• Ryuuen shows his ability to convert information into leverage. Rather than attacking Ichinose directly, he turns her situation into a bargaining tool against Class D and later targets individual identities.
• Sudo displays confidence in Class D’s independent strength by rejecting the assumption that the class must accept Ryuuen’s help.
• Hirata supports a less coercive approach by sending a formal inquiry instead of pressuring Ichinose directly.

Significant Themes

• Kindness has consequences: Goodwill cannot remain cost-free. Ichinose’s attempt to protect both classes forces her to accept suspicion and reduced freedom within Class B.
• Responsibility versus collective blame: The chapter distinguishes one member’s mistake from the position of an entire class, emphasizing the importance of precise evidence and personal accountability.
• Privacy and strategic exploitation: Information becomes dangerous when it can be exchanged for practical advantages. Ryuuen tests whether Class D values a person’s privacy more than success in the Strength Event.
• Consent and coercion: Gu Heng insists that requesting information is permissible, but refusing must remain a genuine option. A favor only becomes a debt when one side is pressured to repay it.
• Transparency and shared responsibility: Class D’s decisions are placed on a public record, and every student is required to understand the consequences rather than allowing one strategist to make the choice for everyone.
• Boundaries in negotiation: The chapter presents exchanges as transactions between clearly stated limits, with both classes testing how far the other will go before violating its principles.

Character Interactions

• Ichinose and Gu Heng establish a cautious but meaningful exchange based on verifiable records rather than trust alone.
• Gu Heng and Horikita discuss Ichinose’s willingness to bear responsibility, contrasting her developing leadership style with their own.
• Class B challenges Ichinose’s loyalty after she shares internal evidence, forcing her to defend the distinction between her personal action and Class B’s collective stance.
• Ryuuen pressures Class D through the Strength Event, attempting to make Ichinose’s information the price of cooperation.
• Gu Heng protects Ichinose by allowing Class D to ask her for clarification while preventing the request from becoming an obligation.
• The closing exchange between Ryuuen and Class D moves the conflict from institutional bargaining toward personal sacrifice, raising the stakes for the next stage.

Chapter Summary: “Refusal Was Also an Option”

Key Plot Points and Events

• Class D reviews Class C’s proposed exchange. Accepting would provide a participant for the Strength Event, but would require revealing the source of information Ichinose had given them. Refusing would protect Ichinose and Class B’s information boundary, though Class D would retain a weakness in its event lineup.
• Sudo refuses to take on both the Strength Event and the first leg of the Relay. Another student also refuses because of the physical strain, while a third agrees conditionally, provided training does not interfere with the Relay.
• Gu Heng orders Hirata to document everyone’s reasons for refusing and prohibits the class from treating refusal as disloyalty or noncooperation.
• Ryuuen pressures Class D by asking how much its “kindness” is worth. Gu Heng ignores him, while Horikita publicly announces that Class D has refused the exchange because it will not disclose its source. She deliberately avoids naming Ichinose.
• Ichinose considers revealing the information herself, but Gu Heng tells her that doing so must be her own decision rather than an act of repayment. She remains silent.
• Class D officially refuses the deal and redistributes the Strength Event responsibilities among three students. The arrangement is not ideal, but it avoids creating additional external losses, and Class D retains its unused authority.
• Ryuuen does not obtain the source, but he learns that Class D is willing to accept a disadvantage to protect it. He concludes that Gu Heng’s principles can be pressured but not directly broken through another person’s name.
• Class C then exposes Class D’s restrictions on the public page without names: limits on consecutive high-intensity events, Relay changes, and source disclosure. This reveals that Class D has a vulnerable gap in the Strength Event.
• Horikita explains that a plan can define acceptable losses rather than guarantee gains. Class D accepts that it may have to redistribute the event or openly acknowledge the weakness.
• The three responsible students record their individual limits and willingness to accept the consequences. Sudo agrees to bear the point difference caused by the gap, but does not claim to speak for the entire class.
• Ryuuen recognizes that each refusal makes it easier to identify who is carrying the burden. He shifts from trying to negotiate a trade to forcing Class D to reveal its most vulnerable member.
• Horikita establishes deadlines for finding a workable arrangement. If no solution appears, Class D will publicly acknowledge the Strength Event gap, turning the failed exchange into a clear and manageable course of action.

Character Developments

• Gu Heng demonstrates that he values protecting personal boundaries and making decisions without sacrificing individuals for an easy strategic gain. He also prevents refusal from being stigmatized and recognizes Ryuuen’s deeper tactic.
• Horikita shows increasing strategic maturity. Rather than hiding the consequences of refusal, she defines them openly and turns an apparent failure into an organized, executable plan.
• Sudo accepts responsibility for the likely scoring loss but refuses to overextend himself physically. His decision reflects both commitment to the class and greater awareness of his own limits.
• Ichinose realizes that Class D is protecting her at a strategic cost. Her offer to reveal the source shows gratitude and willingness to shoulder responsibility, though Gu Heng insists that the decision remain hers.
• Ryuuen adapts quickly. After failing to obtain the source, he shifts toward exploiting Class D’s exposed weakness and identifying the individual most vulnerable to pressure.

Significant Themes

• Refusal as a legitimate strategic choice: Declining a beneficial exchange is not automatically selfish or uncooperative when accepting would violate a fundamental boundary.
• Personal autonomy versus class advantage: The class must balance collective success with the physical limits, commitments, and privacy of individual members.
• Accepting and defining failure: A plan can succeed by limiting damage and clarifying what losses are acceptable, even if it does not improve the projected score.
• Information as a weapon: Protecting the source prevents one danger but creates another by revealing that Class D has a weakness.
• The cost of principles: Class D’s decision preserves trust and confidentiality, but gives opponents evidence that it can be pressured through the burdens its members are carrying.

Character Interactions

• Gu Heng and Horikita: They work together but divide responsibilities. Gu Heng protects the decision-making process and the individuals involved, while Horikita handles the public explanation and class-wide implementation.
• Gu Heng and Ichinose: He acknowledges her right to disclose the source but refuses to let her treat disclosure as repayment for Class D’s protection.
• Horikita and the responsible students: She makes them repeatedly confirm their limits and ensures that accepting responsibility does not become an unlimited obligation.
• Class D and Ryuuen/Class C: Their conflict evolves from a straightforward exchange negotiation into a contest over pressure, public exposure, and the identification of vulnerable members.
• Class D internally: The students confront the fact that protecting their principles will produce a measurable disadvantage, but they are allowed to accept or withdraw from responsibility without being branded as disloyal.

Summary: “Horikita’s Refusal”

Key Plot Points and Events

• After the Strength Event is reassigned, Gu Heng recommends that Sudo take it while the third applicant withdraws from the Relay reserve list. Although this would likely maximize Class D’s results, it would require Sudo to compete in two consecutive events.
• Horikita rejects the recommendation, pointing out that Sudo had agreed only to the Strength Event and had explicitly refused a third high-intensity assignment because of a temporary vacancy.
• Class D instead distributes the Strength Event among four members. This lowers their projected results but prevents Sudo from being overburdened.
• Ryuuen publicly challenges Class D’s decision, accusing them of sacrificing performance to protect Sudo—or Gu Heng’s moral standing. Horikita answers on behalf of the class, while Sudo accepts responsibility for the possibility of losing.
• The third applicant later withdraws from the Relay reserve list because he cannot accept last-minute changes to his training schedule. Horikita records the withdrawal and assigns the vacant scope to another willing member rather than automatically transferring it.
• Gu Heng proposes splitting Sudo’s Strength Event into two shorter periods, but Horikita rejects this as another attempt to go beyond Sudo’s stated consent. Gu Heng accepts the rejection and records the idea as an unadopted proposal rather than an executable plan.
• When Ryuuen asks who has final authority if Class D can reject Gu Heng’s recommendations, Horikita declares that Gu Heng retains the right to propose, but his recommendations do not become class orders automatically.
• Class C then targets Sudo with a new condition. Gu Heng proactively labels his recommendation as “unadopted,” clarifying that it was rejected because of Sudo’s conditions rather than because of a power struggle with Horikita.
• Horikita imposes a new rule: every future recommendation must include its worst possible consequence. Gu Heng agrees, and the review system gains a required risk-assessment field.

Character Developments

• Horikita strengthens her role as a reviewer and boundary-setter. She insists that personal consent and workload limits must be respected, even when doing so reduces the class’s expected results.
• Gu Heng learns that proposing the optimal plan does not give him the authority to enforce it. He begins distinguishing between an executable decision and an unadopted recommendation.
• Sudo demonstrates responsibility and agency by accepting both the consequences of the class’s choice and the possibility of losing because he was not overloaded.
• The third applicant asserts his own limits by withdrawing from the Relay reserve list rather than accepting disruptive changes to his training.
• Ryuuen shifts his attacks from the practical event arrangement to the internal disagreement between Horikita and Gu Heng, testing whether Class D has a clear decision-making structure.

Significant Themes

• Consent versus optimization: The chapter questions whether the best statistical result is acceptable if it ignores an individual’s stated limits.
• Authority and responsibility: Gu Heng may recommend, but Horikita has the authority to reject recommendations, and neither can erase the agency of the people affected.
• Ownership of decisions: Sudo’s willingness to accept the consequences emphasizes that people must recognize a decision as their own rather than merely obeying a superior plan.
• Transparent governance: Reclassifying rejected plans as “unadopted proposals” and requiring worst-case consequences makes the review process clearer and prevents political misinterpretation.
• The cost of fairness: Class D knowingly accepts weaker projected results in order to preserve a realistic and consensual arrangement.

Character Interactions

• Horikita and Gu Heng establish a clearer division of authority: he formulates plans, while she evaluates whether they may be implemented.
• Horikita directly defends Sudo’s conditions and refuses to let Gu Heng reinterpret limited consent as unlimited availability.
• Ryuuen publicly pressures Horikita and Sudo, but Sudo answers calmly and accepts responsibility for the outcome.
• Gu Heng initially continues trying to optimize the arrangement, but gradually accepts Horikita’s refusals and modifies his own proposals to avoid creating the impression of forced orders.
• By the end, Horikita and Gu Heng have not become closer personally, but their professional roles and boundaries are finally explicit.

Chapter Summary: Sudo Wouldn’t Take a Beating for Others

Key Plot Points and Events

• Class C sends Sudo a personal condition: if he publicly admits he is Class D’s strongest fighter, Class C will withdraw from competing in the Strength Event. If he refuses, they will assign opponents to mark him during the official match.
• Sudo refuses to publicly identify himself as the class’s sole fighting strength, but confirms that he will still participate in the Strength Event.
• Ryuuen responds by publishing Class C’s matchup plans early, increasing psychological pressure on Sudo and hoping Class D will rearrange its events to protect him.
• Gu Heng notices an empty slot in Class C’s matchup chart and realizes Ryuuen is waiting for Class D to make broader changes on Sudo’s behalf.
• Rather than moving Sudo to another event, Horikita makes a limited adjustment to the Relay handoff distance. This reduces risk without changing personnel or allowing Class C to claim that its condition succeeded.
• Ryuuen realizes Class D has begun making decisions independently instead of waiting for Gu Heng’s instructions, costing Class C an opportunity to force a replacement.
• Sudo practices the revised relay exchange, honestly reports his fatigue, and confirms both his Strength Event participation and first-leg position. This prevents Class C from exploiting last-minute uncertainty.
• Gu Heng separates Sudo’s refusal statement from his acceptance of being marked into two records, ensuring that neither can later be misinterpreted as a decision made for the entire class.
• The chapter ends with Sudo recognizing that personal responsibility means both refusing to suffer for everyone else and refusing to make others bear the consequences of his own mistakes.

Character Developments

• Sudo: Demonstrates independence and maturity. He refuses to let Class C define him or use his strength as a bargaining tool, yet also refuses to retreat from his event. By checking his physical limits and formally documenting his condition, he takes responsibility for his own decision.
• Gu Heng: Acts as an analyst rather than a protector. He presents Sudo with the consequences of each option but does not choose for him. He also carefully safeguards the wording of Sudo’s decisions.
• Horikita: Shows greater initiative and tactical judgment by adjusting the relay arrangement without overreacting to Class C’s provocation. She begins acting independently rather than relying entirely on Gu Heng.
• Hirata: Helps formalize and separate the class’s statements, ensuring that Sudo’s personal decision cannot be misrepresented as the class’s collective position.
• Ryuuen: Reveals a layered strategy. His goal is not merely to mark Sudo, but to manipulate Class D into changing its entire formation to protect him.

Significant Themes

• Personal responsibility versus collective sacrifice: Sudo refuses to be treated as a resource who must suffer for the class, while also acknowledging that his own choices carry consequences.
• Autonomy and informed choice: Gu Heng’s role emphasizes that offering options is different from making decisions for someone else.
• Psychological warfare: Class C attempts to pressure Class D before the match by publicizing matchups and targeting Sudo’s confidence.
• Precision over overreaction: Horikita’s small relay adjustment succeeds because it reduces risk without giving Class C the larger strategic victory it wants.
• The importance of documentation and interpretation: Separating Sudo’s statements prevents his refusal, participation, and acceptance of being marked from being distorted or combined into a declaration he never made.

Character Interactions

• Sudo challenges Gu Heng to provide a solution, but Gu Heng insists that the final choice must remain Sudo’s.
• Horikita initially considers moving Sudo, but Sudo rejects the idea because doing so would mean surrendering to Class C’s demand.
• Gu Heng informs Horikita of Ryuuen’s hidden intention without dictating a solution, allowing her to act independently.
• Sudo tells Gu Heng not to protect or apologize for him, establishing a clearer boundary between guidance and control.
• Horikita, Hirata, and Gu Heng each contribute differently: Horikita adjusts the strategy, Hirata manages the formal statements, and Gu Heng verifies the rules while preserving Sudo’s autonomy.

Chapter Summary: “Ayanokoji Gives Only Half”

Key Plot Points and Events

• Before the relay match, Ayanokoji gives Gu Heng a Class C matchup chart, claiming it could help Class D adjust its strategy. However, he refuses to reveal or verify the source.
• Gu Heng refuses to treat the chart as confirmed intelligence. He records it only as an unverified possibility and makes clear that he will not invent credibility for Ayanokoji’s information.
• The chart correctly predicts that Class C intends to target Sudo in the first leg, but it omits that Class C has placed a stronger, more enduring runner in the second leg to exploit the baton handoff.
• Class D adapts using Horikita’s judgment. Rather than contesting the exchange line, they maintain their planned exchange distance and avoid falling into Class C’s trap.
• Class D finishes fourth, behind Class C in second and Class B in third. Sudo is not decisively defeated, but Class D does not gain a victory from its adjustment either.
• Gu Heng records the intelligence in separate categories: the first-leg information was verified, the second-leg information was unknown, and the source was unconfirmed.
• Horikita asks whether Ayanokoji should be treated as a risk. Gu Heng instead classifies him as an information provider whose risk level will depend on his future conduct.
• Class C later publishes the matchup chart and accuses someone of leaking information, shifting attention from the relay result to the document’s origin.
• Hirata establishes that Class D members must answer only for what they personally know rather than allowing one person to absorb all suspicion.
• Ayanokoji accepts the new conditions without protest. Cooperation may continue, but incomplete information must be clearly scoped and responsibility must remain traceable.

Character Developments

• Gu Heng becomes more cautious and methodical. He is willing to use Ayanokoji’s information without blindly trusting it, emphasizing verification, documentation, and accountability.
• Ayanokoji reveals that he is willing to share useful information selectively, but only within limits. His partial disclosure suggests either restricted knowledge or deliberate withholding. He accepts Gu Heng’s boundaries rather than trying to force greater trust.
• Horikita demonstrates practical strategic judgment by recognizing Class C’s intended exchange-line pressure and preventing Class D from being manipulated.
• Hirata reinforces Class D’s collective responsibility by insisting that members report only what they know and do not shift suspicion onto one person.
• Ryuuen recognizes that Ayanokoji and Gu Heng are cooperating but are not fully synchronized. He identifies their information gap as a weakness to exploit in the next round.
• Sudo avoids being singled out and crushed, preserving his position and morale despite Class D’s poor overall placement.

Significant Themes

• Partial truth and unreliable intelligence: Information can be useful even when incomplete, but it must not be mistaken for certainty.
• Trust versus verification: Cooperation does not require unconditional trust; it requires clear limits and evidence.
• Accountability: Class D begins building a system in which information, decisions, and mistakes can be traced to their sources.
• Strategic ambiguity: Ayanokoji’s selective disclosures create both advantages and vulnerabilities.
• Institutional discipline versus personal alliances: Gu Heng refuses to protect Ayanokoji through assumptions or fabricated explanations, prioritizing Class D’s records and procedures.
• The cost of caution: Class D avoids Class C’s worst trap but fails to turn its defensive adjustment into a win.

Important Character Interactions

• Ayanokoji and Gu Heng: Their exchange establishes a stricter cooperation agreement. Ayanokoji may provide leads, but Gu Heng will label their reliability and will not claim knowledge he does not possess.
• Gu Heng and Horikita: Gu Heng relies on Horikita to interpret battlefield positioning, while Horikita helps transform uncertain information into a practical adjustment.
• Gu Heng and Hirata: Together they formalize the match’s information into an internal ledger, reinforcing Class D’s procedural approach.
• Gu Heng and Ryuuen: Although they do not directly interact in the chapter, Ryuuen observes their imperfect coordination and plans to exploit it.
• Ayanokoji and Class D: Ayanokoji remains useful but not fully trusted. His future cooperation will depend on whether he clearly identifies the scope of what he knows.

Summary

Key Plot Points and Events

• Class C publicly claims that someone from Class D leaked its matchup arrangements before the competition, indirectly directing suspicion toward Ayanokoji.
• Ryuuen offers no proof and pressures Class D to explain the source. Gu Heng and Horikita respond publicly that Class D received information from an unconfirmed source, used only the portions verified during the event, and did not alter its official lineup.
• The school investigates whether Class D engaged in unauthorized information exchange and demands contact records.
• Gu Heng submits only verifiable records. These show that he contacted Ayanokoji before the competition, but they do not prove that Ayanokoji supplied the matchup chart.
• Ayanokoji denies only that he submitted the chart. His statement leaves unresolved whether he had seen it or indirectly provided the information.
• The school concludes that no unauthorized exchange has been proven, though further investigation remains possible.
• Class D keeps its competition results but loses one Anonymous Information Protection Qualification. Future external deliveries must be signed, timed, and fully documented.
• A supplementary notice establishes that an unknown source is not automatically a violation, but unverifiable information cannot be deleted or replaced by speculation.
• Class D formalizes its records: Horikita stores the notice, Hirata checks attendance, Yukimura organizes page versions, and Gu Heng separately records his contact with Ayanokoji without identifying him as the source.
• Ayanokoji’s connection to Gu Heng is now publicly documented, making future contact more suspicious and harder to conceal.

Character Developments

• Gu Heng acts cautiously and procedurally, refusing to name Ayanokoji without evidence while also refusing to erase their contact from the records. He accepts that suspicion itself creates strategic consequences.
• Horikita supports a fact-based public response and helps preserve the integrity of Class D’s records rather than allowing speculation to dictate its position.
• Ayanokoji remains deliberately ambiguous. He does not defend himself beyond denying that he submitted the chart, protecting his secrecy but allowing suspicion to persist.
• Ryuuen demonstrates his talent for exploiting uncertainty. Although he cannot prove Ayanokoji’s involvement, he succeeds in exposing Class D’s vulnerable connection and forcing stricter oversight.
• Hirata and Yukimura contribute to Class D’s defensive transparency by checking records and organizing evidence.

Significant Themes

• Unknown does not equal guilt: Lack of proof prevents a formal charge, but it does not eliminate suspicion or its practical effects.
• Evidence versus speculation: Class D insists that only verified facts should be publicly asserted, while Ryuuen tries to turn incomplete information into pressure.
• Transparency and risk: Accurate records protect Class D legally, but they also reveal relationships that enemies can exploit.
• Consequences without punishment: Even without proving a violation, Class D loses a protection qualification and faces stricter documentation requirements.
• Information as responsibility: Unrecorded or unverifiable exchanges become liabilities, showing that secrecy itself can create strategic danger.

Character Interactions

• Ryuuen repeatedly challenges Horikita and Gu Heng to identify the source, but they refuse to make unsupported accusations.
• Hirata asks whether an unknown source could eventually become someone’s responsibility, prompting Gu Heng to acknowledge the danger of incomplete records.
• Ryuuen uses Gu Heng’s documented contact with Ayanokoji to intensify suspicion, while Horikita defends the distinction between contact and proof of delivery.
• Ayanokoji and Gu Heng debate whether his name should remain in the internal ledger. Ayanokoji prioritizes minimizing risk; Gu Heng argues that omitting the contact would make the record incomplete.
• Their final exchange emphasizes the chapter’s central tension: being suspected is not conviction, but suspicion still changes how others act.

Chapter Summary: “Real Names Take Freedom First”

Key Plot Points and Events

• After the Anonymous Information Protection Qualification is revoked, all external submissions require real-name verification. As a result, Class C and Class B largely stop communicating with Class D, making the Public Boundary unusually quiet.
• A Class B student anonymously—or rather, under a verified real name—submits a warning that someone may try to register Class D’s Unused Permissions as Gu Heng’s personal property.
• Kushida forwards the information, while emphasizing the distinction between public information and protected personal data. Yukimura verifies the sender’s identity but concludes that the claim itself is only an opinion, not an established fact.
• Horikita orders Class D to review the ownership of the Unused Permissions. The class confirms that they belong collectively to Class D rather than to Gu Heng, Horikita, or any individual.
• This review strips Gu Heng of his former unilateral authority. He can now question the reliability of sources, but he cannot directly alter the class’s decisions.
• Ryuuen offers Class C’s fifty Class Points in exchange for priority over Class D’s next use of the Unused Permissions. Although legal, the arrangement would cost Class D its strategic initiative before the next exam.
• After considering the guaranteed points against the loss of future flexibility, Class D rejects the offer. Every member confirms the decision personally, preserving the class’s options instead of accepting an immediate reward.
• Ryuuen abandons the purchase attempt and instead prepares a public inquiry challenging Gu Heng’s claim to personal ownership of the permissions.
• Sakayanagi observes that Gu Heng has finally returned his authority to the class. The next day, Gu Heng will have to prove that he did not take Class D’s choices away from its members.
• That night, Gu Heng establishes stricter information-handling rules. Real-name data, public information, and personal privacy are separated, and every submission must clearly distinguish between what is proven and what is merely suspected.
• Horikita finalizes the evidence and procedures for the inquiry: ownership of the permissions, actual control over them, and each student’s personal confirmation. Class D also determines who will explain the records, who will review them, and who can reject claims unsupported by their sources.

Character Developments

• Gu Heng: Gradually gives up personal control over the Unused Permissions and accepts that discovering a rule does not grant ownership. He adopts a more cautious, evidence-based approach, preferring limited information over decisions built on unverified assumptions.
• Horikita: Takes the lead in restoring collective authority to Class D. She establishes the review process, blocks Gu Heng’s direct control, and makes the decision to reject Ryuuen’s offer.
• Kushida: Demonstrates greater procedural awareness by distinguishing between public and private information. She continues receiving submissions but accepts tighter rules regarding verification and privacy.
• Yukimura: Serves as a verifier, confirming the identity of the Class B sender while refusing to treat the sender’s interpretation as fact.
• Hirata: Recognizes both the reduced quantity and increased value of information under real-name verification and helps ensure that all students understand the consequences of public records.
• Ryuuen: Shifts from attempting to buy Class D’s strategic resource to attacking Gu Heng’s legitimacy and personal ownership.
• Sakayanagi: Identifies the political significance of Gu Heng’s loss of individual authority.

Significant Themes

• Collective ownership versus individual control: Gu Heng’s discovery of the permissions’ function does not entitle him to control them. The chapter marks a transfer of authority from one strategist to the class as a whole.
• The cost of transparency: Real-name verification makes information more accountable but also discourages people from sharing it, reducing the volume of available intelligence.
• Evidence versus assumption: Class D insists on separating verified facts from judgments, rumors, and interpretations.
• Freedom and responsibility: By refusing fifty Class Points, Class D sacrifices an immediate benefit to preserve future choices and strategic independence.
• Privacy and political power: The distinction between public fields and personal privacy becomes essential as outside actors attempt to use information to challenge Gu Heng’s position.
• Legitimacy through consent: Every class member personally confirms the decision, reinforcing that authority now rests on collective participation rather than Gu Heng’s individual judgment.

Important Character Interactions

• Gu Heng and Kushida: Gu Heng questions why Kushida forwarded the Class B submission, prompting her to explain the limits of her authority. Later, he allows her to continue receiving information but requires stricter classification and verification.
• Gu Heng and Horikita: Their exchange establishes that Gu Heng can no longer control the permissions directly. Horikita openly takes responsibility for the class’s decision-making.
• Gu Heng and the class: When a student argues that Gu Heng should own the permissions because he discovered the rule, Gu Heng rejects the claim himself, acknowledging that discovery does not equal ownership.
• Class D and Ryuuen/Class C: Class D weighs Ryuuen’s offer but rejects it, after which Ryuuen changes tactics and targets Gu Heng’s identity and legitimacy.
• Sakayanagi and Gu Heng: Sakayanagi’s brief message highlights Gu Heng’s political retreat, while his silence suggests he is focused on defending the class’s new collective structure rather than responding personally.

Summary

Key Plot Points and Events

• The school conducts a public inquiry to determine who owns and controls Class D’s unused Exchange Privilege.
• Horikita confirms that the privilege belongs to Class D, while Yukimura presents metadata showing that control is divided:
  • Horikita can submit proposals.
  • Gu Heng can review them.
  • Hirata can confirm members’ statuses.
• Ryuuen probes whether Gu Heng still possesses veto power. Gu Heng clarifies that he can challenge invalid sources but cannot personally veto a choice that Horikita confirms as valid.
• When Sakayanagi asks whose judgment takes priority during disagreements, the class establishes a division:
  • Gu Heng has authority over questions concerning the validity of sources or rules.
  • Horikita has responsibility for the class’s actual choices.
• Ryuuen identifies a possible loophole: Gu Heng could label every disagreement a “source issue.” Horikita counters that she can reject such classifications. The school formally records her Right to Refuse disputed classifications.
• The school adds a penalty: if a review dispute causes a loss of Class Points, Gu Heng receives a linked deduction of five Private Points.
• Gu Heng refuses to resign as reviewer and accepts personal responsibility for the risk.
• After the inquiry, Class D formalizes the limits of each type of review and runs a simulation demonstrating that proposals must pass through separate submission, review, and confirmation stages.
• The new process is slower, but it creates records for disputed classifications and delays, making every participant’s authority traceable and accountable.

Character Developments

• Horikita becomes more assertive in defending Class D’s procedural authority. She establishes that she can reject Gu Heng’s attempts to overextend his review power and insists that disputes leave written reasons.
• Gu Heng accepts responsibility rather than surrendering his reviewer position. His authority is reduced from potential veto power to conditional review, while his judgments now carry personal consequences.
• Hirata retains a distinct administrative role by confirming members’ statuses, reinforcing that the privilege cannot be controlled by one person.
• Yukimura supports the process by documenting authority rules and testing the system through simulations.
• Ryuuen fails to seize control of Gu Heng but successfully exposes a weakness, leading to the five-Private-Point penalty.
• Ayanokoji recognizes that Gu Heng’s judgment now has a concrete cost and warns that others may intentionally manipulate him into making risky decisions.
• Sudo voices concerns about deliberate fake applications and excessive delays, helping highlight the practical burden of the new system.

Significant Themes

• Authority through procedure: The privilege is shown to belong to the class, not to any individual leader.
• Checks and balances: Class D’s “dual-core” structure prevents Horikita or Gu Heng from acting alone.
• Responsibility and accountability: Gu Heng’s review authority is tied to personal losses, ensuring that caution and criticism carry consequences.
• Transparency and traceability: Written reasons, recorded disagreements, and documented delays make abuses of authority visible.
• The cost of collective governance: The new system is slower, but its safeguards prevent unilateral control and protect the class’s ownership.

Character Interactions

• Ryuuen repeatedly challenges Gu Heng’s authority, while Horikita directly limits it.
• Horikita and Gu Heng disagree over the boundaries of review, but their roles become complementary rather than openly antagonistic.
• Ayanokoji privately warns Gu Heng that opponents may exploit the new five-point risk.
• Sudo questions Gu Heng’s decision to remain reviewer, while Gu Heng explains that responsibility cannot be avoided simply by examining fewer cases.
• The final simulation demonstrates cooperation among Gu Heng, Horikita, and Hirata, proving that Class D’s privilege now functions through coordinated institutional roles rather than personal control.

Summary: “Who Audits the Auditors”

Key Plot Points and Events

• After the Five-Point Linked Deduction Rule is introduced, Class D debates how to prevent Gu Heng from holding too much review authority.
• Gu Heng presents two proposals: keep sole review authority with him, or require a three-person vote involving himself, Horikita, and Yukimura.
• Since Horikita and Yukimura acknowledge the limits of their expertise, the class adopts a specialized division of responsibility:
  • Yukimura checks timestamps, page versions, and permissions.
  • Horikita evaluates strategic trade-offs.
  • Gu Heng reviews cross-page sources and rule conflicts.
• Each reviewer can veto only issues within their own field. The arrangement is confirmed through the class’s Personal Responsibility system.
• The first test comes when Class C submits an exchange application containing outdated responsibility information. Although Yukimura verifies the source and Horikita approves the project’s benefits, Gu Heng detects that the responsibility section was copied from an old version.
• Class C refuses to resubmit the relevant confirmation, but Yukimura verifies the version discrepancy. Gu Heng is proven correct, Class D rejects the invalid application, and no points are lost.
• Ryuuen publicly warns that Gu Heng has become Class D’s “final line of defense,” implying that repeated difficult judgments could eventually force Gu Heng to absorb the cost of a mistake.
• A second application is legally valid but demands that Class D surrender one future Public Inquiry right in exchange for a highly desirable project. Since no rule has been violated, Gu Heng cannot reject it himself.
• Horikita separates the question of legality from the question of strategic value, ensuring students do not reject the offer merely because they distrust Gu Heng’s review.
• Hirata gathers opinions without coercing anyone, while Yukimura preserves the relevant versions for comparison. Kushida proposes becoming the sole recipient of outside applications, but Horikita rejects this as another dangerous concentration of authority.
• Gu Heng distributes a risk analysis outlining the proposal’s slower processing, divided responsibility, and possibility of delayed errors. He refuses to force a vote before the class has enough information.
• Horikita establishes a final safeguard: every legal application must be reviewed by the entire class before acceptance, and no submitter’s judgment becomes effective until the Personal Responsibility field is completed.

Character Developments and Interactions

• Gu Heng voluntarily reduces his authority and accepts greater procedural limits, prioritizing accountability over control. He recognizes that valid legal choices—not merely source verification—must belong to the entire class.
• Horikita emerges as the main defender of structural checks and balanced decision-making. She distinguishes objective legality from subjective strategy and resists both Gu Heng’s excessive burden and Kushida’s proposed concentration of power.
• Yukimura honestly limits his role to technical verification, then decisively supports Gu Heng by confirming the version-history error.
• Hirata demonstrates responsible leadership by collecting opinions without pressuring undecided classmates.
• Kushida challenges the new procedures as inefficient and suggests centralizing external communications, but Horikita recognizes the risk and rejects her proposal.
• Ryuuen attempts to expose Class D’s vulnerability by portraying Gu Heng as the single point whose mistakes could damage the class.

Significant Themes

• Accountability and distributed authority: The chapter asks who should judge the people responsible for judging others. Authority is divided so that no individual controls every aspect of a decision.
• Expertise and self-awareness: Each character acknowledges what they can and cannot reliably evaluate, making specialization more effective than a superficial majority vote.
• The danger of centralized power: Both Gu Heng’s original authority and Kushida’s proposed receiving role are treated as potential single points of failure.
• Legality versus strategy: A valid proposal may still carry unacceptable costs, while an undesirable trade is not necessarily an invalid one.
• Shared responsibility: The class cannot delegate every difficult choice to Gu Heng. All members must confront the consequences of exchanging known resources for uncertain opportunities.
• Speed versus reliability: The new system is slower, but it prevents rushed decisions and distributes the risk of error.

Character Interactions

• Gu Heng collaborates with Horikita and Yukimura to create a system based on their different strengths.
• Horikita challenges Kushida’s attempt to centralize application handling and insists that no single person should become the sole contact point.
• Yukimura’s technical verification validates Gu Heng’s judgment in the Class C dispute.
• Horikita forces the class to examine the second proposal separately as a legal transaction and a strategic gamble.
• Ryuuen indirectly targets Gu Heng by publicly emphasizing his growing responsibility.
• By the end, Gu Heng’s authority is narrower, but the class is more directly involved in making consequential decisions.

Summary: “The Price of Strength” Events

Key Plot Points and Events

• Class C offers Class D a Strength Event Participant in exchange for Class D’s Public Inquiry Right for the next round.
• Gu Heng verifies that the exchange is legitimate, with no source errors, refusals, or hidden conditions.
• Class D debates the trade:
  • Accepting would address the class’s weakness in Strength Events.
  • Rejecting would preserve its ability to ask questions and clarify rules.
• Horikita reframes the debate around what each student is willing to lose rather than which option is objectively better.
• Of eight Personal Confirmations, four initially support the exchange, three oppose it, and one student withholds confirmation because the value of Public Inquiry is uncertain.
• Horikita proposes a safeguard: both sides must separately confirm their obligations, and the exchange becomes invalid if Class C’s participant does not complete Personal Confirmation.
• After this condition is accepted, the undecided student votes in favor. The final count is five acceptances and three rejections, allowing Class D to submit the exchange.
• Class D gains the Strength Event Participant but permanently gives up one Public Inquiry Right.
• The school records both sides’ obligations clearly, preventing either class from later redefining the deal.
• Ryuuen announces the next question: whether the Strength Event belongs to the reviewer, the submitter, or the class. This creates the next conflict between the class’s competing internal “cores.”

Character Developments

• Horikita demonstrates stronger leadership by structuring the debate, protecting the class from an ambiguous exchange, and ensuring minority opinions remain recorded rather than suppressed.
• Gu Heng maintains a neutral role. He verifies the validity and source of information but refuses to decide whether the trade is strategically worthwhile.
• Ryuuen reveals that his real objective was not merely for Class D to accept a legitimate cost, but for the class to fracture over it. He is frustrated that Class D reaches a decision without openly turning against itself.
• The undecided student moves from hesitation to acceptance after Horikita secures clearer conditions, showing that uncertainty can be addressed through safeguards rather than pressure.
• The three rejectors remain part of the class’s long-term record. Their warnings are preserved as potential evidence if the decision later proves harmful.

Significant Themes

• The cost of strength: Gaining an immediate advantage requires surrendering future flexibility and explanatory power.
• Majority rule versus minority warnings: A unified decision does not require unanimous agreement. The class accepts the exchange while preserving dissenting viewpoints.
• Responsibility and accountability: Each student must confirm not that the decision is certainly correct, but that they are willing to bear the possibility of being wrong.
• Transparency and precise agreements: Clear sourcing, separate confirmations, and fixed deliverables prevent either side from exploiting vague interpretations.
• Unity without unanimity: Class D’s cooperation is procedural rather than total; disagreement survives within the class and may influence future votes.
• Irreversibility of decisions: Once the exchange is submitted, regret cannot undo it. Future decisions must account for the consequences of the current one.

Character Interactions

• Horikita and the class engage in a structured debate, with Horikita requiring students to identify what loss they are prepared to accept.
• Gu Heng and the undecided student clarify that no one can guarantee the value of Public Inquiry, forcing the class to confront uncertainty directly.
• Horikita and Class C negotiate additional confirmation requirements to protect Class D from an incomplete exchange.
• Ryuuen and Ishizaki discuss Class D’s reaction, with Ryuuen acknowledging that the class has begun accepting real costs but criticizing its failure to fracture.
• Horikita and Gu Heng cooperate after the submission: she organizes the conflicting confirmations, while he validates only the review’s accuracy rather than endorsing either side.
• The chapter ends with Ryuuen targeting the distinction between reviewer, submitter, and class, setting up the next challenge to Class D’s internal structure.

Chapter Summary: “Ryuuen Dismantles the Dual Core”

Key Plot Points and Events

• Ryuuen challenges Class D’s “Dual Core” leadership structure by asking whether the successful acquisition of a strength specialist resulted from Gu Heng’s review or Horikita’s submission.
• Horikita rejects the idea that either person alone caused the outcome. She presents the exchange application, confirmations, and review records to demonstrate that the result depended on several independent actions:
  • Gu Heng verified that the conditions were satisfied.
  • Horikita confirmed the class’s acceptance.
  • Five members accepted responsibility for the exchange.
• Ryuuen then attacks the structure indirectly by distributing two contradictory pieces of intelligence:
  • Gu Heng learns that Class B plans to surrender its questioning right in exchange for Class D’s specialist.
  • Horikita learns that Class B plans to abandon the exchange and retain its questioning right.
• Both sources appear legitimate, creating uncertainty without making either piece obviously false.
• Rather than allowing the conflicting intelligence to divide them, Horikita and Gu Heng classify both reports as unverified and exclude them from the official proposal.
• Ryuuen escalates the pressure when the school announces that only one representative may submit the next proposal within ten minutes. This forces Class D to confront the apparent weakness of having two public decision-makers.
• Class D responds by separating three responsibilities:
  1. Providing factual information.
  2. Taking responsibility for the final choice.
  3. Preserving and recording unused intelligence.
• Hirata and Yukimura help formalize these distinctions, ensuring that the process remains transparent and that unverified information is properly documented.
• Ryuuen publicly releases both contradictory reports and demands that Class D choose a side before the deadline.
• Horikita receives the final submission page from Hirata, while Gu Heng refrains from influencing her decision. The chapter ends with both leaders accepting that one person must bear the consequences of the final submission, even though that person does not become the sole owner of Class D.

Character Developments

• Horikita demonstrates procedural judgment and refuses to let either intelligence report dictate Class D’s decision prematurely. She accepts that submitting the proposal carries responsibility but does not equate submission with absolute authority.
• Gu Heng maintains the independence of his review role. He avoids presenting himself as superior to Horikita and ultimately allows her to choose the submission despite knowing she may reach a different conclusion.
• Ryuuen shifts from directly attacking individuals to testing the structural relationship between Horikita and Gu Heng. His strategy focuses on forcing the Dual Core into a single decision point.
• Hirata helps clarify the distinction between choosing a proposal and verifying its procedural validity. He supports the system without taking over the decision.
• Yukimura contributes by dividing responsibilities into clearly defined categories and checking the timing and documentation of the intelligence.
• Ayanokoji recognizes Ryuuen’s objective: to make Gu Heng and Horikita compete over which one possesses the more reliable truth.

Significant Themes

• Distributed responsibility versus centralized authority: Class D’s success is shown to result from multiple coordinated actions rather than one leader’s decision.
• Trust and verification: Genuine sources can still provide incomplete or contradictory information, so reliability must be assessed without rushing to judgment.
• Leadership under pressure: A temporary single-submitter rule tests whether the Dual Core is truly stable or merely functional when both leaders can act simultaneously.
• Responsibility without ownership: The person who submits the proposal bears its consequences but does not automatically become the class’s supreme leader.
• Manipulation through forced choices: Ryuuen attempts to create conflict by making Class D choose between competing truths, but the class counters by labeling uncertainty instead of treating it as a command.

Character Interactions

• Ryuuen repeatedly questions Horikita and Gu Heng in an effort to establish a superior-subordinate relationship between them.
• Horikita and Gu Heng respond cooperatively, reinforcing that their roles are separate but mutually dependent.
• Their refusal to immediately accept either intelligence report shows that they trust the process more than personal authority.
• Hirata and Yukimura support the two leaders by making the decision-making system more precise rather than choosing sides.
• Ryuuen’s bait does not break the relationship between Horikita and Gu Heng. Instead, it forces them to acknowledge that they must eventually act independently and accept the consequences of their respective choices.

Chapter Summary

Key Plot Points and Events

• With only ten minutes left in the school’s submission window, Class D must finalize its plan despite having two pieces of unverified intelligence.
• Horikita decides not to use either piece. Instead, she places both in the risk section and submits a conservative plan based only on confirmed exchanges, Strength Event participants’ confirmations, and Class D’s remaining authority.
• Gu Heng adds a review objection requiring the plan to explicitly state that the unverified intelligence was not adopted.
• Ryuuen offers Class D the complete sources of the intelligence if Gu Heng is publicly named as Class D’s sole plan designer. Horikita refuses to accept the offer because the intelligence may be false or subject to further manipulation.
• Gu Heng agrees with the rejection, recognizing that the offer would effectively turn him into the public “price” of Class D’s advantage and make the class appear to be his personal creation.
• The class completes its final checks: Gu Heng reviews the plan, Yukimura verifies timestamps, Hirata confirms responsibility statuses, and Sudo submits his Strength Event confirmation.
• Horikita submits the plan just before the deadline, automatically invalidating Ryuuen’s offer. Class D preserves its independence but loses the opportunity to investigate the intelligence and its sources further.
• During the explanation stage, each class must publicly describe what it gave up. Class D identifies its sacrifice as the chance to exchange Gu Heng’s name for an advantage.
• The class chooses Gu Heng to deliver the statement. Horikita ensures that he speaks only for his own judgment rather than falsely presenting the decision as the unanimous view of Class D.
• Internal objections and differing opinions are preserved in the record, while only one carefully limited sentence is submitted publicly.
• The chapter ends as Gu Heng approaches the podium, accepting personal responsibility for explaining Class D’s sacrifice.

Character Developments

• Horikita demonstrates disciplined leadership and accountability. She prioritizes verifiable information over a potentially profitable but unreliable deal and refuses to exploit uncertainty.
• Gu Heng moves from reviewer to public representative. He accepts that rejecting the offer also carries a cost and agrees to bear responsibility for the class’s public explanation.
• Hirata supports procedural fairness by recording differing opinions and confirming that Gu Heng’s statement does not erase other students’ choices.
• Yukimura contributes through precise verification of the plan’s version history.
• Sudo independently confirms his Strength Event participation and becomes an example of an individual decision that should not be misrepresented as the whole class’s stance.
• Ryuuen continues using public pressure and conditional offers to manipulate Class D, but his strategy fails when Horikita refuses to let Gu Heng’s identity become a bargaining chip.

Significant Themes

• Verified truth versus convenient advantage: Class D refuses to treat unverified intelligence as a benefit simply because it might be useful.
• Responsibility and accountability: The chapter distinguishes between making a decision, reviewing it, and publicly bearing responsibility for it.
• Individual judgment versus group consensus: Horikita insists that Gu Heng can explain his own decision but cannot claim that every student shared his view.
• The cost of rejecting manipulation: Class D maintains its integrity but sacrifices opportunities for further inquiry, project advantages, and possible intelligence verification.
• Records versus public image: The class preserves dissent and uncertainty internally rather than creating a simplified image of unity for public consumption.

Character Interactions

• Horikita and Gu Heng debate whether to accept Ryuuen’s offer, with Horikita asking for his judgment and Gu Heng identifying the risks in the proposal.
• Horikita’s refusal to use uncertain information reinforces Gu Heng’s trust in her judgment and pushes him to resume his role as a careful reviewer.
• Gu Heng and the other students conduct a collaborative final review, while Hirata and Yukimura ensure procedural accuracy.
• Before the public explanation, Horikita repeatedly limits Gu Heng’s statement so that it reflects his own responsibility rather than appropriating the opinions of Sudo, the supporters, or the dissenters.
• Gu Heng ultimately accepts the burden of speaking alone, preparing to face the next stage’s questions without relying on the class to defend or reinterpret his decision.

Chapter Summary: “Giving Up Must Be Signed”

Key Plot Points and Events

• During the Grade Statement phase, Class D must submit a single sentence representing the class’s position.
• Gu Heng proposes stating that Class D gives up using personal information in exchange for an immediate advantage. Sudo suggests the stronger wording “We give up victory,” but Horikita rejects it as inaccurate.
• After debate, the class settles on: “Class D gives up using the names of unconfirmed individuals in exchange for an immediate advantage.”
• Every class member must personally confirm whether the sentence is accurate. Although some believe the wording hides the fact that Class D was forced into a disadvantage, Gu Heng insists that all objections remain recorded.
• Horikita submits the statement, Gu Heng verifies its source and scope, and Hirata preserves the dissenting opinions. The statement is officially released.
• Other classes submit their own statements:
  • Class B claims it gives up having collective goodwill bear the consequences of individual actions.
  • Ryuuen submits only Class C’s practical gains.
  • Sakayanagi declares that Class A still has one unused Exchange Privilege.
• The school evaluates the statements for the next special exam without changing Class Points directly. Class D receives a middling evaluation, Class C a high one, and Class B a fluctuating evaluation because of internal disagreement.
• The school then announces that unused special privileges may be retained, but the retaining class must appoint one personally accountable administrator.
• Gu Heng is listed as a candidate. Horikita urges him to take responsibility beyond his previous role as reviewer.
• Gu Heng investigates the administrator’s authority, penalties, and withdrawal conditions before accepting. The class learns that the administrator’s role cannot be delegated or transferred temporarily.
• Horikita opens the decision process to individual review rather than deciding on Gu Heng’s behalf. Class members record both whom they trust and which powers they do not wish to surrender.
• Objections arise concerning Gu Heng combining review and allocation, Horikita’s possible lack of responsiveness, and whether privileges should be retained at all.
• Gu Heng and Horikita acknowledge the objections without removing them. The candidate pool is locked, and the final administrator must personally accept the role that night.

Character Development

• Gu Heng demonstrates a commitment to procedural fairness and accurate wording. He refuses to portray Class D as noble or imply that everyone agreed, preserving opposing views instead. He also recognizes that accepting authority means accepting the possibility of flawed judgment.
• Horikita becomes more careful about separating representation from authority. Rather than forcing Gu Heng to accept responsibility or deciding for the class, she ensures everyone reviews the terms and records their concerns.
• Hirata continues acting as a guardian of transparency by preserving objections and the class’s decision-making record.
• Kushida initially suggests a more favorable statement about protecting everyone, but withdraws it when Gu Heng points out that it would claim goodwill on behalf of people who never consented.
• Sudo highlights the emotional and social cost of holding authority, recognizing that the administrator will be closely watched.
• Class D as a whole becomes more aware that authority cannot simply be passed around and that trust must include clearly stated limits and objections.

Significant Themes

• Accountability and consent: Decisions must be personally confirmed rather than assumed to represent everyone.
• The danger of misleading language: Words such as “give up” can make a forced loss appear voluntary, while favorable phrasing can falsely claim moral credit.
• Transparency over unity: Class D preserves dissent instead of erasing disagreement to create the appearance of consensus.
• Responsibility accompanying authority: Administrative power carries personal penalties, scrutiny, and the obligation to admit the possibility of error.
• Limits of delegation: Important responsibilities cannot be treated as symbolic seals or transferred whenever convenient.
• Institutional memory: The school’s records of objections, confirmations, and authority boundaries may influence future conflicts and evaluations.

Character Interactions

• Gu Heng and Horikita disagree over how the Grade Statement should be framed, but cooperate to ensure it is accurate and properly verified.
• Gu Heng challenges Kushida’s attempt to give the class a protective, morally positive image.
• Hirata supports Gu Heng’s emphasis on preserving dissent by maintaining the record of objections.
• Horikita challenges Gu Heng to move beyond reviewing decisions and consider accepting direct responsibility.
• Gu Heng and Horikita model mutual accountability: neither removes the other’s objections, and both clarify their motives before the class.
• Sudo’s remarks reinforce the pressure surrounding the administrator role, while the class’s collective review establishes that trust must be deliberate rather than assumed.

Chapter Summary: “Administrator Does Not Mean Leader”

Key Plot Points and Events

• Gu Heng and Horikita are the final candidates for the unused authority administrator position.
• Horikita asks the class to review the rules before anyone accepts. The administrator can preserve authority, submit Dispatch Requests, and reject incomplete requests, but cannot complete Personal Confirmation for other members.
• The position carries personal penalties: incorrect dispatches cost twenty Private Points, while malicious concealment incurs heavier consequences.
• The class debates whether Gu Heng, Horikita, or both should assume responsibility, but school regulations permit only one administrator.
• Horikita declines, explaining that she can submit class plans but is not suited to judge every authority dispatch. She identifies Gu Heng’s tendency to treat every mistake as his personal responsibility.
• Gu Heng accepts the position, while explicitly stating that he is accepting management—not leadership. He adds safeguards requiring every dispatch to include a public application, Personal Responsibility, and a review time.
• Ryuuen challenges the arrangement, arguing that Gu Heng effectively controls Class D’s final authority despite not being its leader. Horikita responds that Gu Heng cannot confirm actions for others or submit on behalf of representatives.
• The system reveals Gu Heng’s personal twenty-point risk, reinforcing that his authority is limited by accountability rather than status.
• With the settlement approaching, Gu Heng examines the rules concerning Ryuuen’s remaining legal opportunity to submit a Dispatch Request. He determines that legal but disadvantageous requests cannot simply be rejected.
• Class D establishes a procedure requiring the benefits, losses, and irreversible consequences of any request to be disclosed before processing.
• Hirata records the procedure and relevant times, Yukimura preserves the version history and checks for tampering, and Gu Heng places the decision under his Personal Responsibility.
• The chapter ends by emphasizing that the administrator cannot determine Class D’s outcomes or force members to accept new responsibilities. The position leaves behind records of every decision, making its holder accountable rather than all-powerful.

Character Developments

• Gu Heng accepts a burdensome role despite knowing it will expose his judgment to scrutiny and punishment. He demonstrates caution by imposing transparency requirements and personally reserving the potential penalty.
• Horikita shows stronger judgment by refusing a position she believes does not suit her. She also publicly identifies Gu Heng’s tendency toward excessive personal responsibility and defends the distinction between administration and leadership.
• Ryuuen continues probing Class D’s internal structure, attempting to portray Gu Heng’s authority as hidden leadership.
• Hirata helps formalize the class’s temporary procedure, reinforcing his role as an organizer and protector of collective accountability.
• Yukimura contributes technical oversight by preserving timestamps and monitoring records for alterations.
• Ayanokoji recognizes that Gu Heng’s acceptance has made him publicly measurable and prevents him from hiding behind the claim that he is merely helping.

Significant Themes

• Authority versus leadership: Holding decision-making power does not automatically make someone a leader; authority is defined by its limits and responsibilities.
• Accountability: The administrator’s power is restrained by personal penalties, public records, and explicit responsibility for each decision.
• Transparency and procedure: The class protects itself by documenting applications, consequences, review times, and changes to records.
• Responsibility without control: Gu Heng may decide whether authority is processed, but he cannot control the actions or confirmations of other members.
• The burden of judgment: Gu Heng’s willingness to accept responsibility is both a strength and a vulnerability, since every error can be attributed to him.

Character Interactions

• Horikita and Gu Heng openly discuss their respective strengths and limitations, with Horikita recognizing Gu Heng’s suitability while warning him about his excessive sense of responsibility.
• Ryuuen attempts to undermine Gu Heng by equating administrative authority with leadership; Horikita counters by explaining the administrator’s legal restrictions and personal risks.
• Ayanokoji privately points out that Gu Heng has placed himself in a position where everyone can evaluate and calculate his decisions.
• Hirata, Yukimura, Horikita, and Gu Heng cooperate to create a transparent process that prevents the administrator from acting as an unchecked leader.

Summary

Key Plot Points and Events

• Class C, led by Ryuuen, submits a late-night request asking Class D to postpone settlement of its unused Exchange Privilege by one round. The request is technically valid because one Class C member’s Personal Confirmation Record remains incomplete.
• Gu Heng, as Class D’s administrator, evaluates the consequences:
  • Accepting would preserve Class D’s privilege but allow Class C to retain another Scheduling Window.
  • Refusing would force settlement, remove Class C’s window, and sacrifice some of Class D’s future flexibility.
• Gu Heng consults the class. Sudo favors refusal, while Hirata sees value in postponement. Horikita avoids giving her own answer and instead asks Gu Heng what risks he is personally willing to bear.
• Gu Heng refuses the application, arguing that Class C’s incomplete confirmation should not be converted into an extension of Class D’s privilege. Class C may still complete its confirmation, but it can no longer use Class D’s privilege to prolong the scheduling period.
• Ryuuen accepts the decision calmly and orders that Gu Heng’s reasoning be preserved. He concludes that Gu Heng is no longer merely optimizing outcomes; he is becoming more predictable and therefore easier to calculate.
• The midnight settlement proceeds:
  • Class D retains its unused privilege.
  • Gu Heng’s Private Points are frozen by twenty points until the next exam ends.
  • The used Exchange Privilege settles, granting Class D a Strength Event supplement but costing it a second Relay Event adjustment and a Public Inquiry Right.
  • Other students’ privileges, records, and risks are formally registered.
• Class D completes its phased institutionalization, but Gu Heng’s identity as its administrator becomes known across the grade.
• Gu Heng archives not only actual losses but also pending and potential costs, refusing to treat settlement as a clean reset.
• Ayanokoji delivers notice that the next exam will begin the day after the Sports Festival settlement. The chapter ends with Class D carrying all its unresolved costs, exposed information, and institutional consequences into the next phase.

Character Development

• Gu Heng: Demonstrates independent judgment by refusing the postponement despite its possible strategic benefits. He accepts responsibility for the consequences and develops a systematic habit of recording present, pending, and possible losses. His administrator identity becomes a public liability.
• Horikita: Acts as a sounding board rather than directly influencing the decision. Her questions force Gu Heng to distinguish between points, rules, flexibility, and personal responsibility.
• Sudo: Shows a strict, rule-based attitude by supporting refusal and insisting that Class D should use only the time explicitly provided.
• Hirata: Takes a more cooperative and flexible position, believing postponement could benefit both classes. He is also entrusted with helping monitor future administrator privileges.
• Ryuuen: Displays restraint and strategic insight. Instead of reacting emotionally to rejection, he studies Gu Heng’s decision-making style and identifies its increasing predictability.
• Ayanokoji: Remains detached but attentive, contributing by delivering the next phase’s notice and ensuring the transition is formally recorded.

Significant Themes

• Settlements do not erase consequences: Formal resolution merely transfers past decisions and losses into the future.
• Responsibility versus optimization: Gu Heng chooses the option he can justify and bear, rather than simply the one with the highest apparent strategic value.
• Records and institutional memory: Written records cannot prevent exploitation, but they stop the class from pretending that past costs never occurred.
• Predictability as both strength and weakness: Gu Heng’s principles make him more consistent, but also allow opponents like Ryuuen to calculate his likely actions.
• Rules and ownership: A benefit created by Class C’s incomplete status should not be treated as something Class D is entitled to use or extend.
• Institutionalization and exposure: Class D gains a more formal structure, but Gu Heng’s public role creates a new vulnerability for the class.

Character Interactions

• Gu Heng consults Sudo, Hirata, and Horikita before making the administrator decision, revealing differing philosophies about rules and flexibility.
• Horikita challenges Gu Heng to define what risk he personally accepts, deepening his sense of accountability.
• Ryuuen and his recorder discuss Gu Heng’s refusal, interpreting it as evidence of a shift from opportunistic optimization to principled, predictable decision-making.
• Gu Heng and Hirata discuss the importance of tracking potential costs.
• Ayanokoji quietly delivers the next exam notice, reinforcing his role as an observer who influences the class without directly taking control.

Chapter Summary: “Class D’s Own Answer”

1. Key Plot Points and Events

• After the previous settlement, Class D receives the school’s complete official records of the stage evaluations, exchange results, and individual responsibilities.
• Although Class D does not win first place or earn the highest evaluation, it succeeds in protecting everyone’s identities and preventing Class C from obtaining its source person, unused authority, or a weakness in the class’s structure.
• The class openly debates whether this outcome counts as a victory. Rather than forcing a unified interpretation, Gu Heng allows everyone to retain their own judgment, and Hirata archives the differing opinions.
• Horikita and Gu Heng establish a formal “dual-core” leadership structure. Their cooperation is based on mutual oversight rather than obedience, with Horikita retaining the right to challenge Gu Heng’s classifications.
• The next special exam is announced: a “Rooftop Special Exam,” though its rules, point system, and expulsion conditions remain unknown.
• Gu Heng places the announcement in the class’s public archive instead of keeping it as his personal responsibility. He asks Class D to begin preparing by considering what each person is willing to bear.
• For the first time, the students begin acting independently rather than waiting for Gu Heng, Horikita, or Ayanokoji to decide everything.

2. Character Developments

• Gu Heng: Moves away from being the sole decision-maker. He continues accepting responsibility but deliberately leaves space for others to make and own their choices.
• Horikita: Becomes Gu Heng’s equal counterpart rather than a subordinate. She asserts her authority to question and reject his classifications when necessary.
• Hirata: Strengthens his role as the class’s archivist and coordinator, preserving disagreement instead of erasing it in favor of a false consensus.
• Sudo: Recognizes the physical cost of his efforts and voluntarily reduces his future training. This marks a shift toward responsible self-management rather than treating endurance as simple weakness or pride.
• Kushida: Establishes a limited but concrete boundary with Gu Heng, agreeing to submit information under her real name within public fields. Their relationship remains distrustful but becomes more structured.
• Ichinose: Accepts the consequences of becoming an internal witness for external delivery. She emphasizes that her decision must be recorded officially rather than dismissed as something Gu Heng merely “understands.”
• Ayanokoji: Remains a hidden strategist but agrees, implicitly, to continue working with Gu Heng without making decisions on his behalf. His contrast with Gu Heng’s public role becomes clearer.
• Ryuuen: Suffers a strategic loss despite Class C receiving a higher evaluation, as he fails to penetrate Class D’s defenses.
• Sakayanagi: Observes that Class D’s real achievement is not gaining a stronger leader, but creating a process that makes its leader personally bear the cost of his decisions.

3. Significant Themes

• Shared responsibility: Class D begins shifting from dependence on exceptional individuals to collective ownership of decisions.
• Accountability and transparency: Official records, archives, and real-name submissions ensure that actions cannot be erased or reduced to private promises.
• Leadership versus control: Gu Heng’s leadership becomes more effective because he stops monopolizing decisions, while Horikita’s challenge prevents the structure from becoming authoritarian.
• The cost of choice: The upcoming exam is framed not only around strategy, but around what each student is personally willing to sacrifice or endure.
• Individual autonomy: Students begin making independent decisions about their bodies, information, authority, and responsibilities.
• The danger of the school’s system: The school remains harsh and exploitative; Class D has not changed the rules, only developed a stronger way to confront and discuss their consequences.

4. Character Interactions

• Gu Heng and Horikita formalize a cooperative but adversarial partnership built on mutual checks.
• Gu Heng and Sudo discuss whether their outcome qualifies as victory, leaving the judgment to the class rather than imposing one.
• Kushida and Gu Heng negotiate a practical boundary for future information submissions.
• Ichinose and Gu Heng confirm that her decision will be preserved in Class B’s records.
• Sakayanagi’s assessment highlights the effect of Gu Heng’s leadership on Class D.
• Ayanokoji and Gu Heng reaffirm their cooperation while acknowledging their different approaches: Ayanokoji works from the shadows, while Gu Heng remains publicly accountable.

Overall Significance

The chapter marks Class D’s transition from a class controlled by rules and dependent on powerful individuals into a group capable of debating, recording, and accepting responsibility for its own choices. Gu Heng remains central, but he no longer writes every answer himself. The blank page becomes a symbol of the class’s developing independence and its readiness to face the next exam together.

Afterword Summary

Key Plot Points and Events

• The author reflects on the story’s progression from its opening with 100,000 points to its conclusion on a blank final chapter page.
• Major events referenced include:
  • The class points being reset to zero
  • The Sudo incident
  • The establishment of the first class rule
  • The Uninhabited Island and cruise ship exams
  • Interference and probing from other classes
  • The “Dual Core” division of responsibilities
  • Final decisions that required each Class D member’s personal confirmation
• The story ends not with a dramatic victory, but with Class D reaching its own answer to the central question of how it should function.
• The author explains that the fic stopped at this point because the most important stage of Class D’s development was complete.

Character Development

• Gu Heng was designed not as a stronger version of Ayanokoji, but as a different kind of strategist. He understands rules, calculates risks, and negotiates, while also being willing to reveal his burdens and return decisions to the people affected by them.
• Gu Heng gradually learns that leadership is not about deciding everything for others. Instead, it means presenting the costs, recognizing everyone’s right to refuse, and accepting personal responsibility when no perfect choice exists.
• Horikita refuses to become Gu Heng’s unquestioning executor. She maintains the distinction between reviewing, submitting, and leading, and repeatedly asserts her independence.
• Hirata demonstrates that kindness does not mean unconditional cooperation. He sets limits on information, trust, and participation.
• Sudo develops from a volatile liability into someone capable of managing his responsibilities proactively, including adjusting his workload around his physical condition.
• Kushida is not simply “seen through” or defeated. Her danger, testing of others, and limited cooperation continue to have consequences.
• Class D’s members mature by earning the ability to reject Gu Heng’s solutions rather than merely accepting them. Their growth is measured by increased independence and responsibility, not by becoming colder or more powerful.
• Ayanokoji remains the calculating observer and benchmark against whom Gu Heng’s different approach is contrasted.

Significant Themes

• Leadership versus control: A true leader does not impose answers but makes the costs clear and allows others to choose.
• Personal responsibility: Those who make decisions must be willing to bear their consequences rather than shifting them onto others.
• Collective independence: Class D’s development lies in no longer depending on a single person to determine its path.
• Strength through openness: Strength does not require emotional detachment, perfect judgment, or superiority. It can involve sharing burdens and respecting disagreement.
• The right to refuse: Growth occurs when people are trusted to reject even a seemingly correct plan.
• Individuality within an established world: Gu Heng cannot replace the original characters; he must find a distinct role among their established personalities, limits, and strategies.
• Completion despite imperfection: The author acknowledges flaws in pacing, repetition, character relationships, and exposition, but emphasizes that the work was genuinely completed.

Character Interactions

• Gu Heng’s relationship with Horikita is defined by debate and resistance rather than obedience; her refusals force him to recognize the limits of his authority.
• His interactions with Hirata establish boundaries around trust and information, preventing cooperation from becoming blind support.
• His relationship with Sudo reflects a shift from managing a dangerous problem to recognizing Sudo as someone capable of self-management.
• Kushida challenges Gu Heng and the class through manipulation, testing, and partial cooperation, leaving lasting effects rather than being neatly resolved.
• Ayanokoji functions as a constant observer of Gu Heng, allowing the story to contrast two forms of strategic leadership: Ayanokoji’s control from behind the scenes and Gu Heng’s willingness to place choices back in others’ hands.
• By the end, Gu Heng is no longer the sole person at the forefront. Class D contains people willing to lead, object, accept risks, and make independent choices.

Overall Conclusion

The afterword presents the story’s ending as Class D’s achievement of collective agency. The school’s harsh rules remain unchanged, but the class has developed its own response to them. The story ultimately becomes less about Gu Heng winning for everyone and more about Class D learning to make, question, and bear its own decisions.
