Chapter Summary: “Slightly Altered Events”

1. Key Plot Points and Events

• After submitting the Student Council’s disciplinary application concerning the incident involving Sudo Ken, Shiraishi Makoto checks whether Sakura Airi has taken any recent photographs. He confirms that she was not present during the incident and therefore cannot become an inconvenient witness.
• Shiraishi asks Horikita Manabu for permission to participate in judging the dispute and requests special authority to review school surveillance footage. Manabu approves the request, recognizing Shiraishi’s intention to investigate the case independently.
• Shiraishi suspects that Class C deliberately lured Sudo and framed him, taking advantage of his reputation as someone likely to be accused of violence.
• Reviewing the available footage, Shiraishi discovers that:
  • Sudo and three Class C students entered the Special Building.
  • Sudo left first.
  • The Class C students emerged injured, apparently supporting their accusation.
  • By tracking them through other cameras, Shiraishi sees them enter a private room at a KTV in Keyaki Mall.
  • When they leave, their injuries are visibly worse, and they are limping.
• The footage reveals that Ryuen Kakeru was responsible for beating the three Class C students and that the incident was likely staged to implicate Sudo.
• Shiraishi submits an incident verification report to the Student Council rather than extracting the footage immediately.
• He questions Manabu about the school’s willingness to allow students to be wrongly accused. Manabu explains that surviving class competition requires students to protect themselves and withstand attacks from other classes.
• Shiraishi also asks whether he can privately obtain the evidence. Manabu refuses to allow him to misuse Student Council authority, but explains that Shiraishi can purchase the files through his homeroom teacher.
• Shiraishi pays Hoshinomiya Chie 50,000 Private Points to obtain copies of the relevant footage.
• Although the evidence could potentially lead to Ryuen’s expulsion, Shiraishi decides not to expose him yet. Instead, he plans to use the evidence to threaten or manipulate Ryuen, since Ryuen’s continued actions will be useful during the upcoming Uninhabited Island Exam.

2. Character Development

• Shiraishi Makoto demonstrates increasing strategic awareness and political skill. He uses Student Council authority carefully, gathers evidence without revealing his full intentions, and recognizes that information can be more valuable as leverage than as a means of immediate punishment.
• He also shows concern for Sakura Airi by deliberately ensuring she is not drawn into the dispute or exposed to unnecessary attention.
• Horikita Manabu acts as a gatekeeper of institutional authority. He recognizes Shiraishi’s motives but permits the investigation, emphasizing that Class D’s response to the crisis will reveal its strength and unity.
• Ryuen Kakeru is shown to be calculating and ruthless. He orchestrates a false accusation against Sudo and personally beats his own allies to make the deception convincing.
• Sudo Ken remains vulnerable because of his violent reputation; even his classmates and opponents would find the accusation believable.
• Sakura Airi is indirectly characterized as someone who has become emotionally dependent on Shiraishi’s company, having stopped taking photographs alone.
• Hoshinomiya Chie functions as a representative of the school’s transactional system by selling access to the evidence for a large number of Private Points.

3. Significant Themes

• Power and institutional authority: The Student Council’s ability to access surveillance and investigate disputes gives its members significant influence over class conflicts.
• Class competition and survival: The school treats deception, wrongful accusations, and strategic attacks as legitimate parts of competition. Students are expected to defend themselves rather than rely on fairness.
• Reputation and prejudice: Sudo’s past behavior makes him an easy scapegoat, showing how existing reputations can be weaponized.
• Truth versus usefulness: Shiraishi uncovers the truth but does not immediately reveal it. He values the evidence primarily for its strategic potential.
• Money and corruption within the system: Although public authority cannot be used for private benefit, information can still be obtained through Private Points, blurring the line between official justice and personal advantage.
• Manipulation and controlled outcomes: Shiraishi chooses not to end Ryuen’s scheme because Ryuen’s future actions may benefit him, showing that he is willing to preserve an enemy when doing so serves a larger plan.

4. Character Interactions

• Shiraishi and Sakura exchange messages, with Shiraishi checking whether she could testify and quietly protecting her from involvement.
• Shiraishi and Manabu discuss the case, Student Council authority, the weaknesses of Class D, and the school’s harsh philosophy toward class competition.
• Manabu refuses Shiraishi’s request for a private transaction but guides him toward legally purchasing the evidence through his homeroom teacher.
• Shiraishi interacts indirectly with Ryuen through the surveillance evidence, gaining a powerful means of control over him without confronting him directly.
• The chapter also highlights the contrast between Manabu’s institutional authority and Shiraishi’s more flexible, covert manipulation of information.

Summary of “July’s Class Points”

Key Plot Points and Events

• On July 1, the school distributed the delayed Class Points from the Midterm Exam. Class A received 100 points, bringing it to 1,150 despite an unexplained five-point loss the previous month. Class B rose to 1,130, while Classes C and D had 585 and 87 points respectively.
• Class A’s shrinking lead over Class B motivates the students to prepare seriously for the upcoming Final Exam. Ichinose proposes that everyone study together in the library, and even lower-performing students commit to taking time off from clubs.
• Class D receives its 87 Class Points but does not receive the corresponding Private Points. Their distribution has been delayed because of an unresolved dispute involving Class C.
• Chabashira informs Sudo that he must meet her after school. Later, Sudo explains to the group that Class C has submitted evidence accusing him of assault, leading to his impending suspension.
• Sudo recounts the incident: after being considered for the basketball team’s Summer Tournament roster, he was summoned to the Special Building by Basketball Club members Komiya and Kondo. Ishizaki from Class C was also present. They objected to a Class D student becoming an official player, threatened him, and attacked him when he refused to quit. Sudo admits he defeated all three in the resulting fight but insists he was provoked and falsely accused.

Character Developments

• Kushida Kikyo reacts warmly to Sudo’s basketball opportunity but struggles to understand how it connects to the assault.
• Ike Kanji provides comic relief and voices the class’s anger over the delayed Private Points.

Significant Themes

• Class competition and pressure: Class A’s narrow lead over Class B creates urgency and unites the students around the Final Exam.
• Fairness and institutional control: The school’s delayed payments and opaque handling of the dispute highlight how little control students have over the system governing their rewards and punishments.
• Reputation and social prejudice: Sudo appears to have been targeted because he belongs to Class D, suggesting discrimination between classes.
• Provocation versus responsibility: Although Sudo claims self-defense, his willingness to fight leaves him vulnerable to punishment, raising questions about whether intent or results matter more.
• Cooperation and leadership: Class A’s willingness to study together contrasts with the hostility and manipulation surrounding Class D and Class C.

Character Interactions

• Hoshinomiya encourages Class A, while Ichinose turns that motivation into a concrete group-study plan.

• Ike teases Sudo about his nervousness, prompting Sudo’s embarrassed anger.
• Ayanokoji and Horikita discuss the withheld points and begin linking them to the conflict with Class C.
• In Ayanokoji’s room, Sudo explains the basketball-club incident to Ayanokoji, Horikita, Kushida, and Ike. Kushida congratulates him on his potential roster position, while the others focus on understanding how the confrontation led to his suspension.

Chapter Summary: “Profiting from the Crisis”

Key Plot Points and Events

• Sudo Ken explains that the school has given him until the following Tuesday to prove that the three students he fought attacked first. If he fails, he will be blamed for the incident, suspended until summer break, and potentially cause Class D to lose its newly earned 87 Class Points.
• The class discusses the situation and realizes that the opposing students may have deliberately provoked Sudo. They apparently endured his attacks without fighting back so that Sudo could not claim self-defense.
• Horikita Suzune emphasizes that emotional appeals to the teachers will not be enough; Sudo needs decisive evidence proving that the other students initiated and manipulated the confrontation.
• Meanwhile, Shiraishi Makoto visits Shiina Hiyori in the library. Because Class C has been avoiding him and he lacks Ryuen Kakeru’s contact information, he asks Hiyori to arrange a meeting with Ryuen.
• Hiyori contacts Ryuen, who agrees to meet Shiraishi at 6:30 p.m. Shiraishi then calls Hoshinomiya-sensei and asks her to notarize a contract, revealing that he plans to make a formal deal with Class C.
• Shiraishi arrives with a prepared contract and meets Ryuen in the school building. Ryuen has already guessed that Shiraishi discovered Class C’s involvement in the Sudo incident and intends to exploit the situation for profit.
• Ryuen directly challenges Shiraishi to explain his purpose. Shiraishi openly states that Ryuen’s actions involving Sudo were poorly concealed and that he has uncovered their involvement.

Character Developments

• Sudo Ken: His anger and frustration become clear as he realizes that his impulsive reaction could cost him his place on the official team and severely damage Class D. He must now rely on evidence rather than force or emotion.
• Horikita Suzune: Demonstrates practical leadership and clear judgment. She recognizes that the school will not trust Sudo without proof and urges him to control his temper.
• Ayanokoji Kiyotaka: Offers the key insight that the opposing students intentionally accepted Sudo’s attacks to make him appear unquestionably guilty.
• Shiraishi Makoto: Shows himself to be calculating and opportunistic. Rather than helping Class D directly, he plans to use his knowledge of Class C’s scheme to force Ryuen into a profitable agreement.
• Ryuen Kakeru: Displays unusual caution and seriousness. He understands that Shiraishi has discovered something damaging but agrees to meet because negotiation may still prevent the situation from worsening.
• Shiina Hiyori: Acts as the intermediary between Shiraishi and Ryuen. Though outwardly polite and cooperative, her fading smile and private message suggest she is observant and aware that Shiraishi may have uncovered more than he realizes.

Significant Themes

• Manipulation and manufactured guilt: The incident was designed to make Sudo appear solely responsible, showing how violence can be strategically staged to control the narrative.
• Evidence versus emotion: Sudo’s anger cannot protect him; only concrete proof can overcome the school’s judgment.
• Exploitation of conflict: Shiraishi treats the crisis not as a moral issue but as leverage, intending to profit from Class C’s vulnerability.
• Power through information: Knowledge of the truth gives Shiraishi bargaining power over Ryuen, while Ryuen’s awareness of Shiraishi’s intentions prevents him from being easily intimidated.
• Contracts and formal authority: Shiraishi’s prepared agreement and request for a teacher’s notarization indicate that the conflict is moving from covert manipulation into an official negotiation.

Important Character Interactions

• Class D members debate Sudo’s case, with Kushida suggesting they appeal to a teacher, Horikita rejecting that approach, and Ayanokoji explaining the opponents’ deliberate strategy.

• Shiraishi and Ryuen meet for the first time, immediately recognizing each other as strategic opponents.

Chapter Summary: “Signing the Contract”

Key Plot Points and Events

• Ryuen Kakeru meets Shiraishi Makoto, who confronts him about Class C’s involvement in injuring Ishizaki and two other students.
• Shiraishi shows Ryuen surveillance footage proving that the victims’ injuries worsened after meeting Ryuen’s group. Although the footage does not directly show an assault, it is enough to expose the weakness in Ryuen’s scheme and potentially let Class D turn the situation against him.
• Recognizing that Shiraishi has evidence but is willing to negotiate, Ryuen agrees to discuss terms.
• Shiraishi proposes a contract in which:
  • Class A will not actively interfere in the conflict between Classes C and D.
  • Class C will compensate Class A with 300 Class Points during future special exams.
  • The points must be earned through verifiable actions, such as deliberately losing to Class A or providing intelligence that helps Class A gain points.
• Ryuen adds restrictions to protect Class C, including banning Shiraishi from sharing the surveillance footage and preventing other Class A students from helping Class D.
• After extensive bargaining, both sides sign the agreement with homeroom teacher Hoshinomiya Chie as witness.
• Shiraishi deletes the footage from his phone in front of Ryuen, though he has retained the ability to obtain another copy if necessary.
• Ryuen leaves determined to eliminate the remaining traces of his scheme and avoid giving Shiraishi further leverage.

Character Developments

• Shiraishi Makoto demonstrates exceptional observation, planning, and negotiation skills. He identifies Ryuen’s weakness almost immediately and turns evidence into a favorable long-term arrangement for Class A.
• Ryuen Kakeru is forced to acknowledge Shiraishi as a genuine strategic threat. Although he maintains his confidence and negotiates aggressively, he realizes he must now operate more carefully and within the school’s rules.
• Hoshinomiya Chie becomes increasingly fond of Shiraishi, admiring how much effort he puts into helping Class A. She also continues to show her playful, gossip-loving personality.
• Ichinose Honami is indirectly emphasized as the person Shiraishi trusts to explain the agreement to Class A, reflecting her importance and reliability within the class.

Significant Themes

• Strategy and leverage: Information is treated as a weapon, and Shiraishi gains power by discovering evidence rather than openly attacking Ryuen.
• Rules and loopholes: Both characters exploit the school’s formal system while avoiding direct violations. The contract shows how conflicts can be controlled through legalistic agreements.
• Pragmatism over immediate profit: Shiraishi chooses Class Points instead of Private Points because they will have a greater long-term impact, particularly in the upcoming Uninhabited Island Exam.
• Mutual respect between rivals: Ryuen dislikes the difficulty Shiraishi creates but respects his intelligence and recognizes him as a formidable opponent.
• Responsibility and leadership: Shiraishi’s actions are focused on strengthening Class A, while Hoshinomiya observes that he sacrifices a normal student life for his class.

Character Interactions

• Shiraishi and Ryuen: Their confrontation develops into a tense but respectful negotiation. Ryuen tries to conceal his wrongdoing, while Shiraishi calmly controls the situation through evidence and precise terms.
• Shiraishi and Hoshinomiya: Hoshinomiya teases Shiraishi, pinches his cheek, and praises his accomplishments. She then urges him to explain the contract to the class and jokingly questions his relationship with Ichinose.
• Shiraishi and Ichinose: Though Ichinose does not appear directly, Shiraishi indicates that she is the only classmate who needs a full explanation, suggesting his trust in her judgment and leadership.

Chapter Summary: “The Necrotic Arm”

Key Plot Points and Events

• Bound by his contract, Shiraishi Makoto gives Ichinose Honami only a simplified explanation of his plan: he has discovered Class C’s weakness, negotiated a contract favorable to Class A, and hopes Ichinose will persuade their classmates not to interfere.
• Shiraishi deliberately prevents Class A from intervening in Class D’s conflict with Class C. He wants Class A to witness the cruelty of class competition and develop a stronger awareness that class interests must come first.
• Ichinose initially feels uneasy about abandoning Class D, but ultimately trusts Shiraishi’s judgment and agrees to keep Class A uninvolved. She warns her classmates to stay in groups, protect themselves, and focus on the Final Exam.
• Class D begins searching for witnesses who can support Sudo Ken’s claim that he acted in self-defense. Hirata Yosuke and Kushida Kikyo organize the investigation, while Horikita Suzune refuses to participate.
• Horikita argues that Sudo’s repeated aggression makes him partly responsible for the incident. She views him as Class D’s major weakness—an otherwise powerful “arm” that has become necrotic and is continuously damaging the class.
• After two days of searching, Class D finds no witnesses, and the students’ willingness to help Sudo weakens. Horikita suggests that the class may as well accept the penalty, since they have very few Class Points left.
• Sudo becomes enraged when he realizes that his classmates largely agree with Horikita. He accuses them of being useless and resents having to bear the consequences alone.
• Horikita responds that Sudo’s current crisis is a consequence of his own repeated behavior. Kouenji then mocks Sudo and suggests that he should drop out, provoking Sudo into kicking a desk and escalating the tension.

Character Developments

• Shiraishi Makoto: Demonstrates a strategic, long-term approach. Rather than immediately rescuing Class D or exposing his full plan, he uses the incident to educate Class A about the harsh realities of school competition.
• Ichinose Honami: Shows her loyalty to Shiraishi and Class A by suppressing her natural compassion for Class D. She begins to recognize that protecting her class may require emotionally difficult decisions.
• Horikita Suzune: Becomes more pragmatic and openly critical of Sudo. She recognizes that individual weaknesses can threaten the entire class and begins considering whether saving Sudo is worthwhile or whether Class D should abandon him.
• Sudo Ken: Remains impulsive, defensive, and unable to accept criticism. His anger at his classmates reveals his lack of self-awareness and his failure to understand how his behavior affects Class D.
• Kushida Kikyo and Hirata Yosuke: Take active leadership roles in the search for witnesses, attempting to preserve Class D’s unity and protect Sudo despite the lack of evidence.
• Kouenji Rokusuke: Continues to behave arrogantly and independently, but his blunt mockery exposes the seriousness of Sudo’s position and further provokes him.
• Ayanokoji Kiyotaka: Observes the conflict quietly, recognizing Horikita’s excuse for refusing to help but choosing not to challenge her further.

Significant Themes

• Class interests versus personal morality: Ichinose must set aside her instinct to help others, while Class D must decide whether protecting Sudo is worth the cost.
• The consequences of personal behavior: Sudo’s history of violence and recklessness makes it difficult for others to believe he is merely a victim.
• Strategic restraint: Shiraishi’s decision to stand aside shows that intervention can sometimes weaken a class by preventing its members from learning necessary lessons.
• Weakness within a group: Horikita’s “necrotic arm” metaphor presents Sudo as a strong but damaged member whose continued presence may harm the entire class.
• Responsibility and sacrifice: The chapter raises the question of whether a group should continue supporting a flawed member or cut its losses for the sake of collective survival.
• The harshness of competition: Class D begins confronting the reality that the school’s system rewards cold calculation rather than simple solidarity.

Character Interactions

• Shiraishi and Ichinose: Shiraishi persuades Ichinose to suppress her compassion and support his strategy. Their exchange emphasizes trust, loyalty, and the conflict between kindness and pragmatism.
• Ichinose and Class A: Ichinose instructs her classmates to remain uninvolved, reinforcing her growing commitment to Class A’s interests.
• Kushida and Horikita: Kushida asks Horikita to assist with the investigation, but Horikita refuses and criticizes the wisdom of repeatedly rescuing Sudo.
• Horikita and Sudo: Horikita directly confronts Sudo about his responsibility for the situation, while Sudo reacts with anger and resentment.
• Kouenji and Sudo: Kouenji’s condescending remarks push Sudo toward losing control, ending the chapter with a violent outburst.
• Class D as a whole: The class gradually shifts from supporting Sudo automatically to questioning whether he deserves their limited resources and loyalty.

Chapter Summary: “Identity Exposed”

Key Plot Points and Events

• Sudo Ken nearly attacks Kouenji Rokusuke after Kouenji harshly criticizes him during Class D’s investigation. Hirata intervenes and reminds Sudo that another violent incident during his suspension could lead to expulsion. Sudo regains control but leaves angrily, slamming the door.
• Kouenji refuses to take responsibility for provoking Sudo and casually leaves for a date. His behavior further damages Class D’s morale, causing many students to conclude that expelling Sudo might be the easiest solution.
• Ayanokoji points out that the school likely uses surveillance cameras to record violations. However, the investigation reveals that there were no cameras at the location where Sudo attacked the Class C students.
• Horikita recognizes the central problem: because Sudo truly injured them and the three Class C students maintain consistent testimonies, Class D has little chance of proving his innocence.
• The chapter then reveals that Sakura Airi’s identity as the popular online idol “Shizuku” has been exposed. A Third-Year student recognizes her in the cafeteria, and the news quickly spreads throughout the school.
• Sakura’s classmates are shocked to learn that the quiet, withdrawn girl is a famous idol. Ike and Yamauchi are especially surprised, while Yamauchi awkwardly attempts to cover up his earlier false claim that Sakura had confessed to him.
• Shinohara, Matsushita, Kushida, and others help Sakura handle the sudden attention. Thanks to her recent friendships, Sakura is more socially capable than before and does not flee or completely shut down.
• After several days, the attention surrounding Sakura fades. She becomes more accepted within Class D and gradually forms friendships, helped by her photography skills and increased confidence.
• Class D’s attention returns to Sudo’s dispute hearing. On Tuesday afternoon, Class D goes to the Student Council office, where the three Class C students, their teacher Sakagami, Ryuen, and several Student Council representatives are already waiting.

Character Developments

• Sudo Ken: Shows how difficult it is for him to control his temper, but Hirata’s intervention helps him avoid another serious violation. His vulnerability to provocation leaves him in a dangerous position.
• Kouenji Rokusuke: Remains arrogant, self-centered, and unconcerned with the class’s problems. He refuses to admit fault and prioritizes his personal plans over Class D’s crisis.
• Hirata Yosuke: Continues acting as a mediator and protector of the class, trying to prevent Sudo from worsening his situation.
• Ayanokoji Kiyotaka: Contributes a practical investigative idea by drawing attention to the school’s surveillance system, though even he cannot find evidence that will overturn the case.
• Horikita Suzune: Quickly understands the structural weakness in Class D’s position: without proof contradicting the Class C students, Sudo’s genuine involvement makes him highly unlikely to win.
• Sakura Airi: Experiences a major personal challenge when her secret identity is exposed. Although embarrassed and overwhelmed, she handles the attention better than she would have earlier, showing gradual social and emotional growth.
• Shinohara Satsuki and Sakura’s other friends: Demonstrate genuine support by protecting Sakura from excessive attention and helping her adapt to her newfound visibility.
• Yamauchi Haruki: Reveals his dishonesty again by trying to deny and rewrite his earlier claim about Sakura’s supposed confession.

Significant Themes

• Reputation and public perception: Sudo’s reputation as a violent student and Sakura’s reputation as a famous idol both influence how others judge them, regardless of their full circumstances.
• Evidence versus truth: Even if Sudo’s actions were manipulated by Ryuen, the absence of surveillance footage and the consistency of Class C’s statements leave Class D unable to prove what really happened.
• Manipulation and power: Ryuen’s apparent efforts to worsen the Class C students’ injuries demonstrate how easily rules and institutions can be exploited.
• Personal growth through relationships: Sakura’s improved ability to cope with attention reflects the positive effect of her new friendships.
• Class unity and selfishness: Hirata and Sakura’s friends work to support others, while Kouenji and many Class D students prioritize themselves or give up when the situation becomes difficult.

Character Interactions

• Hirata physically restrains and verbally calms Sudo before he can attack Kouenji.
• Hirata confronts Kouenji about provoking Sudo, but Kouenji dismisses the criticism.
• Ayanokoji and Horikita cooperate indirectly in examining the incident and recognizing the lack of useful evidence.
• Shinohara, Matsushita, Kushida, and other girls shield Sakura from the attention caused by her exposed identity.
• Ike and Yamauchi discuss Sakura’s fame, with Yamauchi trying to conceal his previous lie.
• Class D arrives at the dispute hearing and faces Ryuen, the injured Class C students, their teacher, and the Student Council, setting up the formal confrontation.

Summary: “Class D’s Plan”

Key Plot Points and Events

• The Student Council convenes a formal cross-examination between Classes 1-C and 1-D over the violent confrontation involving Class C students Ishizaki Daichi, Komiya Yogo, and Kondo Suzune, and Class D student Sudo Ken.
• Class C presents medical reports documenting their injuries, while Class D has no physical evidence and must rely on testimony and logical inconsistencies.
• Sudo claims Komiya and Kondo summoned him to the Special Building, while the Class C students insist that Sudo called them and attacked them without provocation.
• The meeting initially begins poorly for Class D. Sudo loses his temper, contradicting the prepared strategy, and the students’ accounts remain directly opposed.
• Horikita Suzune, who is unusually nervous because her brother, Student Council President Horikita Manabu, is presiding, struggles to participate. Ayanokoji quietly helps her regain her composure.
• Suzune questions Class C about why Ishizaki, who was not part of the basketball team, was present. Class C claims he was brought along as protection because of his reputation for violence.
• Suzune then introduces Class D’s central argument: Ishizaki was known as a capable fighter, yet none of the three Class C students fought back against Sudo. This behavior is suspicious and suggests they intentionally provoked Sudo, allowed themselves to be injured, and attempted to frame him.

Character Developments

• Sudo Ken: His impulsive and hot-tempered nature undermines Class D’s prepared strategy. Although he insists he was provoked, his inability to remain calm makes him appear less credible.
• Horikita Suzune: Initially paralyzed by her brother’s presence, she gradually recovers and delivers Class D’s first effective counterargument. Her questioning reveals growing confidence and strategic ability.
• Ayanokoji Kiyotaka: Remains in the background but discreetly supports Suzune by helping her regain focus when she begins to falter.
• Ryuen Kakeru: Remains confident and amused, closely observing the proceedings rather than showing concern about Class C’s position.
• Horikita Manabu: Presides over the meeting with detached authority. His presence increases Suzune’s anxiety, but he also gives her permission to proceed when she finally speaks.
• Tachibana Akane: Moderates the dispute impartially, controlling interruptions and demanding that both classes provide clear explanations.
• Shiraishi Makoto: Observes Ryuen and the proceedings with interest, recognizing that events may be unfolding differently from the original course of events.

Significant Themes

• Truth versus evidence: The meeting demonstrates that the truth cannot be established by competing claims alone; credibility depends on evidence, consistency, and logical behavior.
• Manipulation and framing: Class D suggests that Class C deliberately engineered the confrontation to make Sudo appear guilty.
• Emotional control: Sudo’s anger weakens his testimony, while Suzune’s ability to overcome her anxiety becomes crucial to Class D’s defense.
• Strategic reasoning: Rather than directly disproving Class C’s evidence, Suzune identifies an abnormality in their behavior and uses it to challenge the official narrative.
• Authority and pressure: Manabu’s presence highlights Suzune’s insecurities while also testing her ability to act independently.

Character Interactions

• Tachibana repeatedly intervenes when Sudo and Komiya interrupt or become aggressive, maintaining order.
• Sudo and the Class C students openly contradict one another, with their argument escalating until Tachibana forces them to calm down.
• Suzune directly challenges Komiya, Kondo, and Ishizaki’s account, forcing them to explain Ishizaki’s presence.
• Suzune’s questions expose Class C’s reliance on Ryuen, as the three students instinctively look toward him before answering.
• Ayanokoji quietly assists Suzune, while Manabu’s approval allows her to present Class D’s main theory.
• The chapter ends with Class D shifting the focus from Sudo’s aggression to the suspicious possibility that Class C intentionally staged the incident.

Chapter Summary: “The Appeal of Numbers”

Key Plot Points and Events

• Class D argues that Class C deliberately provoked and framed Sudo Ken, while Class C claims that Sudo attacked their three students without provocation.
• Horikita Suzune aggressively exposes weaknesses in Class C’s story. She points out that the incident occurred near the school gate, where the injured students could easily have sought help, and questions why they supposedly stood by while Sudo defeated them one by one.
• Ryuen Kakeru takes over Class C’s defense. Rather than insisting that his classmates were completely innocent, he proposes a compromise: Class C’s students should receive one-week suspensions, while Sudo should be suspended for two weeks because of the severity of the injuries.
• The homeroom teachers accept this compromise. Horikita objects, insisting that Sudo is innocent and that Class C set him up, but the argument devolves into mutual accusations.
• Student Council President Horikita Manabu ends the hearing. He states that one side has clearly told a serious lie and gives both classes until the following afternoon to produce decisive evidence. If neither side succeeds, the proposed suspensions will be enacted; conclusive proof could lead to expulsion.
• After the first hearing, Student Council members observe that Class D has made progress by exposing contradictions in Class C’s explanation, though their evidence remains insufficient.
• The next day, Class D submits a voice recorder as new evidence. The recording captures Ishizaki discussing how he would have beaten Sudo if not for their plan, while Ryuen orders the injured students to remain in their rooms until the review hearing.
• The recording directly contradicts Class C’s claim that its students were merely innocent victims. Ishizaki panics, Ryuen is visibly shocked, and the evidence appears to confirm that the incident was staged.
• Shiraishi recognizes the recorder and realizes that Ayanokoji was responsible for obtaining it, concluding that he had underestimated Ayanokoji’s abilities.

Character Developments

• Horikita Suzune becomes more forceful and effective in questioning Class C. Although she initially fails to overcome the evidence problem, she successfully identifies inconsistencies and refuses to accept the compromise punishment.
• Ryuen Kakeru demonstrates his tactical flexibility. Recognizing that Class C’s story is vulnerable, he abandons absolute denial and attempts to negotiate a punishment that shifts greater blame onto Sudo.
• Sudo Ken remains emotional and confrontational, vehemently denying the accusations and reacting angrily to Class C’s claims.
• Horikita Manabu acts as a decisive and impartial authority. He recognizes that one side is lying but refuses to determine the truth without stronger proof, giving both classes one final opportunity.
• Shiraishi Makoto is established as an exceptionally observant Student Council member. He notices Class C’s weaknesses and later identifies Ayanokoji’s involvement in securing the recording.
• Ayanokoji does not appear directly, but his planning and abilities become crucial to Class D’s case.

Significant Themes

• Truth versus evidence: The hearing shows that being morally correct is not enough; claims must be supported by convincing proof.
• Manipulation and strategy: Both classes attempt to control the narrative, while Ryuen uses compromise as a way to minimize Class C’s losses.
• Institutional justice: The Student Council must weigh conflicting accounts and physical evidence, emphasizing procedure over emotion.
• Hidden intelligence and teamwork: Class D’s success depends on gathering information indirectly, revealing that unseen strategists can influence events more than visible leaders.
• The value of numbers and recording technology: The voice recorder transforms suspicion into concrete evidence, demonstrating how objective data can overturn a carefully constructed lie.

Character Interactions

• Horikita Suzune repeatedly challenges Komiya and the other Class C students, forcing them into increasingly weak explanations.
• Ryuen counters Horikita’s accusations and negotiates with the teachers to secure a favorable compromise.
• Horikita Manabu suppresses the students’ emotional arguments and imposes a final deadline.
• Shiraishi and Manabu discuss the progress of the case, with Shiraishi’s observations influencing the president’s understanding of Class C’s deception.
• In the second hearing, the recording exposes a private conversation between Ryuen and Ishizaki, turning Class C’s own words against them and leaving both visibly shaken.

Chapter Summary: “Ayanokoji’s Misunderstanding”

Key Plot Points and Events

• Ishizaki Daichi accidentally exposes Class C’s premeditated plan against Sudo Ken by mentioning “the plan.”
• Horikita Suzune presents a secret recording of Class C students discussing the scheme. The evidence leaves Class C unable to defend itself during the hearing.
• The school rules that Ishizaki, Komiya Yogo, and Kondo Suzune deliberately provoked and framed Sudo. They are suspended for three weeks, and Class C loses 200 Class Points, falling from 585 to 385.
• The Sudo Incident is officially resolved in Class D’s favor.
• Afterward, Shiraishi Makoto meets Ayanokoji Kiyotaka on the rooftop and learns that Ayanokoji secretly planted a voice recorder on the Class C students, later retrieving it to obtain the incriminating evidence.
• Ayanokoji explains that he became involved because he believed Shiraishi wanted Horikita Suzune to be challenged and forced to grow. Shiraishi clarifies that while he did want Horikita tested, Ayanokoji had greatly exaggerated the extent of his intentions.
• The two reaffirm their agreement: Ayanokoji will not directly attack Shiraishi’s Class A, but he may assist Class D and arrange for Horikita to face Shiraishi in future exams.
• Shiraishi warns Ayanokoji that someone influential from outside the school has demanded the expulsion of a student. This unusual intervention may be connected to Ayanokoji’s hidden past.
• Later, Shiraishi meets Ichinose in the library. She comments on Class D’s victory, while Shiraishi calmly studies and remarks that Ayanokoji is considered a “seriously defective product,” despite his extraordinary abilities.

Character Developments

• Ayanokoji Kiyotaka: Demonstrates his intelligence, stealth, and willingness to intervene directly when necessary. He also reveals that he has been observing the relationship between Shiraishi and Horikita Manabu and has interpreted their harsh treatment of Horikita Suzune as an attempt to develop her.
• Shiraishi Makoto: Gains a clearer understanding of Ayanokoji’s methods and motives. He admits that his original goal was mainly to build a relationship with Horikita Manabu, not necessarily to push Horikita Suzune as severely as Ayanokoji assumed. He also begins acting as Ayanokoji’s informant regarding outside threats.
• Horikita Suzune: Successfully uses the recording to overturn the case, showing greater competence under pressure. However, Shiraishi still views her as poorly suited to leadership because of her rigid personality and lack of underhanded tactics.
• Ryuen Kakeru: Is forced into a defensive position when the recording exposes Class C’s scheme. His caution saves him from harsher punishment, since he avoided saying anything incriminating on the recording.
• Ichinose Honami: Remains impressed by Class D’s unexpected victory and recognizes the significance of the case.
• Ishizaki and the other Class C students: Receive formal punishment for their role in framing Sudo.

Significant Themes

• Misunderstanding and interpretation: Ayanokoji misreads Shiraishi’s intentions, believing he is fully committed to harshly training Horikita Suzune, while Shiraishi’s motives were more limited and strategic.
• Hidden ability and indirect influence: Ayanokoji prefers to remain unnoticed, yet his covert actions decisively shape the outcome. His power lies in manipulating events without claiming credit.
• Growth through conflict: Horikita Suzune’s development is treated as something that must be forced through challenges, rivalry, and exposure to stronger opponents.
• Deals and boundaries: Ayanokoji and Shiraishi maintain a careful agreement not to attack each other’s classes directly, while leaving room for indirect competition.
• Secrets and outside control: The threat of an external figure demanding a student’s expulsion hints at Ayanokoji’s mysterious background and suggests that forces beyond the school may soon affect the conflict.

Character Interactions

• Horikita Suzune and Class C: Horikita uses Ayanokoji’s evidence to defeat Ryuen’s class during the disciplinary hearing.
• Ryuen and Horikita: Ryuen is visibly suspicious of how Horikita acquired the recording, especially because the conversation occurred privately in an elevator.
• Shiraishi and Ayanokoji: Their rooftop discussion reveals Ayanokoji’s reasoning, clarifies their agreement, and establishes that Horikita may eventually be used as a challenger against Shiraishi’s Class A.
• Shiraishi and Hoshinomiya Chie: Though Hoshinomiya does not appear directly, her investigation and warning provide Shiraishi with information about the external expulsion demand.
• Shiraishi and Ichinose: Their library conversation contrasts Ichinose’s admiration for Ayanokoji with Shiraishi’s detached assessment of him as an exceptionally capable but supposedly “defective” student.

Chapter Summary: “Class C Seems Ready to Forfeit”

Key Plot Points and Events

• Hoshinomiya explains the island exam’s detailed rules and penalties. Withdrawing costs 30 points, polluting costs 20, missing roll call costs 5 per person, and violence or theft against another class results in immediate disqualification.
• Each class must establish a permanent base and select a leader. The leader receives a check-in card and must attend roll call at 8 a.m. and 8 p.m.
• Students can earn temporary points by checking in at facilities around the island, but each facility can only be used once every eight hours. Unauthorized use results in a 50-point penalty.
• The most dangerous rule concerns identifying class leaders: correctly guessing another class’s leader earns 50 points, while having one’s own leader discovered—or making a wrong guess—costs 50 points. If all three opposing classes identify a class’s leader, that class loses 150 points.
• Shiraishi instructs Kanzaki and Ichinose to lead Class A to a suitable clearing while he handles a private matter.
• Shiraishi approaches Ryuen and negotiates for Class C to purchase supplies with Exam Points. Ryuen claims Class C is considering giving up on the exam, arguing that enduring the hardship may not be worth the points they can preserve.

• After Shiraishi leaves, Ryuen reveals that his apparent resignation was a deception. His cheerful demeanor disappears, and he begins preparing a separate plan for Class C.

Character Developments

• Hoshinomiya Chie: Acts casually and playfully but becomes serious when explaining the leader system, emphasizing how strategically important the exam will be.
• Shiraishi Makoto: Demonstrates practical leadership and strategic thinking. He recognizes that survival equipment will be more valuable than entertainment and takes advantage of Ryuen’s apparent willingness to give up.

• Ryuen Kakeru: Pretends that Class C is ready to forfeit in order to manipulate Shiraishi into revealing his priorities and obtaining a favorable arrangement. His final reaction shows that he remains calculating and dangerous.

Significant Themes

• Survival versus competition: The exam requires classes not only to endure harsh living conditions but also to compete for points and strategic advantages.
• Information and deception: The identity of each class leader is potentially worth 50 points, making secrecy and misdirection central to success.
• Resource management: Practical supplies may determine a class’s ability to survive, while unnecessary luxury items tempt students to waste points.

Class D’s Situation — Chapter Summary

Key Plot Points and Events

• Kanzaki Ryuji discovers Class D’s riverside campsite while fetching water. Class D treats him cordially because Class A has helped them financially and has not antagonized them.
• He learns that Class D has taken in Ibuki Mio from Class C, who claims she was expelled after an argument and assault by a classmate.
• Kanzaki reports back to Shiraishi Makoto, also noting that Class D has only four eight-person tents and has spent very few Exam Points. This suggests they have not found any supply locations and are prioritizing point preservation over comfort.
• Shiraishi reveals that Ryuen Kakeru claimed Class C intended to abandon the exam. The group reasons that Class C may be avoiding spending points because doing so would leave them with little chance of earning additional points.
• Shiraishi questions why Kaneda Satoru, who was expected to go to Class A, has not appeared. He suspects Class C may have shifted its strategy toward Class B after failing to cooperate with Katsuragi.

• Ibuki Mio: Her arrival in Class D confirms that conflict within Class C has caused students to be driven away, though her true circumstances remain uncertain.
• Ryuen Kakeru: Though absent, he influences the chapter through his misleading claim that Class C will give up and through the unexplained movements of his classmates.
• Class A: Becomes more pragmatic, conserving food and points while adjusting the check-in schedule to reduce unnecessary danger and exhaustion.

Significant Themes

• Resource management and sacrifice: Every point, item of food, and comfort matters. Class A willingly tolerates bland meals and reduced routines to maximize its final score.
• Information and deception: The classes conceal their true strategies, while Shiraishi and Kanzaki analyze campsites, movements, and spending habits to infer opponents’ plans.
• Risk versus reward: The revised check-in system reflects the need to balance earning points with the physical dangers of nighttime travel.
• Rules as strategic tools: Shiraishi exploits the exam’s withdrawal rules, recognizing that losing 30 points by leaving is preferable to losing 50 or more if another class correctly identifies him.

• At dawn, Ayanokoji secretly searches Ibuki Mio’s backpack, suspecting that the Class C student is carrying something unusual. He finds a digital camera, an item forbidden unless purchased through the school’s Exam Point exchange system. He returns it without being detected, choosing not to confront Ibuki yet.
• Class D begins its second day on the island. After waking, the students maintain their planned routine: cooking breakfast, collecting water, exploring the island, fishing, and making tools from natural materials.
• Shiraishi, Ichinose, and Kanzaki complete their check-in route much faster than the previous day because Shiraishi has optimized the path.
• Afterward, they visit Class C’s base near the beach and discover that Class C has spent most of its points on leisure facilities and entertainment rather than survival supplies.
• Class C students relax with beach chairs, parasols, jet skis, inflatable boats, volleyball, and other luxuries. Their behavior suggests that Ryuen’s class has effectively abandoned the competitive aspect of the exam.
