Chapter Summary

Key Plot Points and Events

• Tatsuya Sakuya returns to the freshman dormitory with supplies purchased from the underground supermarket and receives his room assignment: Room 217.
• In the elevator, he encounters his socially anxious classmate Airi Sakura. Rather than forcing conversation or staring at her, Tatsuya deliberately gives her personal space and allows her to relax.
• After settling into his room, Tatsuya reflects on the competitive nature of Advanced Nurturing High School. He decides that promises and class loyalty are unreliable and that concrete evidence is the most powerful protection.
• He spends 28,500 points on a Sony PCM-A10 high-quality audio recorder, viewing it as the school’s “strongest weapon” because recorded evidence could help him gain leverage and earn more points.
• At Keyaki Mall, Tatsuya finds Airi being pressured by an aggressive electronics clerk into buying an expensive DSLR she does not need.

  • Yamauchi falls asleep.
  • Kouenji openly leaves class to visit a hair salon without permission.
• Chabashira does not stop or punish any of them, causing the class to assume that university courses allow students almost complete freedom.
• After the ninety-minute lecture, Chabashira reflects that the class is just as undisciplined—and possibly worse—than previous Class 1-D groups. She recognizes that their behavior should cause Class Point deductions, which will reduce their future Private Points.
• Once she leaves, the students celebrate surviving the lesson and plan to spend the break at Keyaki Mall.

Character Developments

• Ayanokouji Kiyotaka remains quiet and observant, watching the class’s behavior rather than participating.
• Horikita Suzune continues to display her intense commitment to academics and her disdain for laziness and disorder. She is suspicious of the school’s excessive benefits and senses that hidden risks must exist.
• Tatsuya Sakuya acts polite and composed, attempting to build a normal relationship with Horikita. He also analyzes the teacher’s leniency logically rather than reacting emotionally.

Significant Themes

• Class discipline and collective consequences: Individual misconduct threatens the entire class because Private Points depend on Class Points.
• Appearance versus reality: Chabashira’s passive behavior makes the lesson seem consequence-free, but her internal observations suggest that the school is quietly recording and penalizing the students.

• Airi Sakura messages Tatsuya Sakuya, explaining that Haruka’s absence stems from boys making crude comments about her body during class. Sakura asks him to help.
• Tatsuya meets Haruka privately. Instead of dismissing her distress, he affirms that the boys’ behavior was wrong and that she is entitled to report it.

Chapter Summary

• Setting and initial events: Before Class 1-D’s swimming test, the boys gather excitedly while the girls prepare in swimsuits. Hasebe Haruka, uncomfortable with the attention, sits in a shaded corner of the bleachers wearing a fully zipped school jacket. Airi Sakura joins her and quietly offers support. Sakura later waves to Tatsuya Sakuya, establishing a friendly connection between them.
• Harassment of Hasebe: Ike Kanji and Yamauchi Haruki notice Hasebe and begin making crude comments about her body. Their remarks escalate into a vulgar betting game involving her breast size. The surrounding boys encourage them, taking advantage of the noisy pool environment and the absence of close supervision. Hasebe overhears enough to become upset and prepares to leave, but Sakura stops her and pleads with her to stay.
• Horikita confronts the boys: Horikita Suzune also hears the boys’ comments. Although she is normally uninterested in defending classmates or intervening in personal matters, her disgust at the sexual harassment—and her irritation at the damage it does to the class’s already poor atmosphere—drives her to confront Ike and Yamauchi. She threatens to report them to Chabashira.
• The confrontation escalates: Ike and Yamauchi dismiss Horikita’s threat, claiming they were only joking and mocking her for being meddlesome. Other boys laugh, leaving Horikita isolated despite being morally correct. Her usual intimidating attitude and the boys’ lack of shame make ordinary warnings ineffective.
• Sakuya’s intervention: Tatsuya Sakuya steps in and separates Ike and Yamauchi from the group. Rather than arguing about morality, he frightens them by reminding them that Horikita’s surname is significant: her brother is the Student Council president, Horikita Manabu. Once they realize the possible consequences of antagonizing the Student Council president, Ike and Yamauchi immediately retract their arrogance, apologize repeatedly, and beg Horikita not to report them.
• Horikita’s suspicion: Ayanokouji quietly observes the entire incident. After Sakuya begins to leave, Horikita stops him. She has deliberately concealed her relationship with the Student Council president since entering the school, so she is shocked that Sakuya knows about it. She demands to know what he has done, ending the chapter on a note of suspicion and confrontation.

Character Development and Interactions

• Hasebe: Her discomfort with sexual attention and reluctance to expose herself emotionally are emphasized. Her reaction shows how deeply the boys’ comments affect her, while Sakura’s intervention highlights their growing friendship.
• Sakura: Acts as Hasebe’s quiet protector, offering both companionship and emotional support.
• Horikita: Demonstrates a strong sense of standards and order, confronting harassment despite her normally detached personality. However, she is also angered that Sakuya revealed or exploited her connection to her brother.
• Sakuya: Shows himself to be perceptive, calm, and strategically intelligent. Instead of trying to shame Ike and Yamauchi, he identifies the pressure that will actually control them and uses Horikita’s family name to end the conflict immediately.
• Ike and Yamauchi: Their apparent boldness is exposed as cowardice. They act shamelessly when they believe there are no consequences, then become extremely submissive once they fear intervention from the Student Council president.
• Ayanokouji: Remains a detached observer, silently analyzing the situation rather than participating.

Significant Themes

• Power over morality: The boys ignore Horikita’s legitimate moral argument but immediately submit when faced with the possibility of institutional punishment. The chapter suggests that authority and fear are more effective than ethical appeals for certain people.
• Hidden identities and family influence: Horikita’s relationship with Manabu has been deliberately concealed, making Sakuya’s knowledge significant and potentially threatening.
• Sexual harassment and social pressure: The scene exposes the casual cruelty of group behavior, showing how harassment is encouraged when individuals believe they can avoid consequences.
• Appearance versus reality: Ike and Yamauchi pretend to be fearless and rebellious, but their behavior changes instantly when their social position is threatened. Horikita’s cold exterior also contrasts with her underlying sense of justice and concern for class discipline.

Chapter Summary

Character Developments

• Tatsuya Sakuya: Reveals extraordinary swimming ability and a competitive drive motivated partly by the opportunity to earn Private Points. His performance exposes that his apparent laziness and average test results may conceal exceptional physical capabilities.

• Chabashira Sae: Takes particular notice of Sakuya after witnessing his unexpected record-setting performance.

Significant Themes

• Competition and rewards: The swimming test demonstrates how the school’s point-based system motivates students and encourages them to reveal or exploit their abilities.

• He leaves his dorm and visits Keyaki Mall to buy ingredients for braised chicken legs, eggs, bok choy, and the alcoholic mixture.
• While shopping, he recognizes Kamuro Masumi from Class 1-A and secretly records her stealing a canned beer from the supermarket.
• Tatsuya follows Kamuro outside and confronts her about the theft. She initially denies it and assumes he is stalking her because he is romantically interested in her.
• When he shows her the recording and threatens to expose the incident, Kamuro becomes frightened and defensive, believing he intends to blackmail or sexually exploit her.
• Tatsuya clarifies that he only wants a favor: she must help carry his groceries back to the dorm, after which he promises to delete the video.
• Kamuro reluctantly agrees but remains highly suspicious and prepares to defend herself if he makes any inappropriate move.

Character Developments

• Tatsuya Sakuya: Shown as curious, impulsive, mischievous, and opportunistic. He confidently exploits his knowledge of Kamuro’s theft, but he is not actually seeking sexual or financial gain; his immediate goal is practical assistance carrying his purchases.
• Kamuro Masumi: Revealed to be bold and skilled at shoplifting, carefully using surveillance blind spots. However, she becomes nervous and emotionally overwhelmed when confronted with evidence. Her defensive attitude and readiness to fight show both her distrust and determination to protect herself.

Significant Themes

• Mischief and manipulation: Tatsuya turns Kamuro’s theft into leverage, creating an uneasy power imbalance.
• Appearance versus reality: Kamuro assumes Tatsuya is a stalker or blackmailer, while his intentions are comparatively harmless. Likewise, her cool, confident exterior hides anxiety when exposed.
• Surveillance and privacy: The mall’s security system and Tatsuya’s phone recording emphasize how easily private actions can be documented and used against someone.
• Comedic misunderstanding: Kamuro’s assumptions, influenced by adult-film scenarios, heighten the chapter’s humor and tension.

Chapter Summary: “A Chain Reaction Sparked by a Bowl of Shaxian Snacks”

Key Plot Points and Events

• Kamuro Masumi visits Tatsuya Sakuya’s dorm room to return his belongings and demand that he delete the incriminating video he recorded.
• Although she insists she is not hungry, her stomach growls. Sakuya cooks Shaxian-style food—braised chicken legs, eggs, and bok choy—and persuades her to eat.
• Sakuya deletes the video in front of Kamuro, easing the immediate threat against her.
• Kamuro becomes absorbed in the delicious meal, even taking the chicken leg and egg from Sakuya’s bowl.
• During their conversation, Kamuro admits that she steals not out of financial necessity but because breaking rules gives her excitement and releases dopamine. However, she strongly does not want to be expelled.
• Sakuya considers giving her “Flammable Oolong Tea” as a risky source of excitement, but Doubao’s warning identifies the drink as dangerously flammable, so it is not consumed.
• The two discuss the political divisions among their classes. Sakuya hopes to build alliances with Class 1-A because both Class 1-A and Class 1-C oppose Class 1-B.
• Sakuya proposes that Kamuro become his girlfriend as a safer way to seek excitement. Kamuro interprets this as a predatory advance, becomes defensive, and threatens to call the police.
• Sakuya insists that he is genuinely trying to help her avoid expulsion, though he admits that his proposal is only “half true, half false.”

Character Developments

• Kamuro Masumi: Initially guarded and focused on protecting herself, she gradually relaxes while eating Sakuya’s food. Her appetite and blunt behavior reveal a more casual, uninhibited side. She openly acknowledges her thrill-seeking tendency and recognizes that it could endanger her enrollment, but she has no clear alternative.
• Tatsuya Sakuya: Demonstrates domestic competence and uses food to build trust. He is observant of Kamuro’s habits and tries to find a substitute for her rule-breaking. His attempt to help is mixed with teasing, opportunism, and an unexpectedly direct romantic proposal, making his intentions difficult to read.
• Relationship: The pair move from a coercive situation involving blackmail to a more cooperative, though still suspicious, interaction. Sakuya gains Kamuro’s attention through food and conversation, while Kamuro remains wary of his motives.

Significant Themes

• Thrill-seeking versus consequences: Kamuro’s stealing provides excitement but threatens her future, creating a conflict between immediate stimulation and long-term security.

• Food as a means of connection: The shared meal breaks down Kamuro’s resistance and creates an unexpectedly intimate atmosphere.
• Alliance-building and school politics: Sakuya views interpersonal relationships strategically, seeking cooperation between classes against common rivals.

• Kamuro’s enthusiastic eating contrasts with her initially cold attitude and leads to playful exchanges over the food.
• Sakuya questions her motives for stealing, prompting her candid explanation.
• Their discussion of class factions shows Sakuya’s strategic thinking and Kamuro’s awareness of Class 1-A’s internal divisions.
• Sakuya’s girlfriend proposal shocks Kamuro, who accuses him of being a pervert and prepares to contact the police. He defends it as an unconventional solution to her dangerous habit, leaving their relationship unresolved and ambiguous.

• Karuizawa Kei observes his sudden rise in status and begins considering him as a potential source of protection.
• Remembering her history of severe bullying, Karuizawa recognizes that her cheerful gyaru persona and wide social circle are defensive measures designed to prevent her from ever becoming powerless again.
• Although Hirata Yousuke’s public relationship with her has protected her socially, she concludes that his peaceful, non-confrontational nature cannot offer the absolute protection she wants.

2. Character Developments

• Tatsuya Sakuya: His swimming victory changes him from an overlooked student into a respected and influential figure. Despite Karuizawa’s attractive appearance and bold proposal, he remains calm and analytical rather than becoming flustered. He accepts the arrangement partly because of the generous payment and appears willing to understand and accommodate Karuizawa’s hidden personality.
• Karuizawa Kei: Her confident, fashionable gyaru image is revealed to be a carefully constructed shield against the trauma of prolonged bullying. She becomes increasingly aware that social popularity alone is insufficient protection and seeks someone physically and psychologically stronger. Tatsuya’s athletic ability and new reputation convince her that he may be the reliable protector she needs.
• Hirata Yousuke: Though still portrayed as kind and influential, Hirata is shown to be limited by his desire to mediate rather than confront problems directly. Karuizawa no longer sees him as capable of providing complete security.

Chapter Summary: “If You Don’t Come, I’m Ditching the Order?”

Key Plot Points and Events

• Bored in his dorm room on Sunday, Tatsuya Sakuya messages his client and fake girlfriend, Karuizawa Kei, demanding that she meet him for a “date.” He jokingly threatens to “ditch the order” if she refuses.
• Tatsuya also contacts Kamuro Masumi to ask about a previous matter. When she ignores him, he sends a fake 10,000-point red packet containing only 100 points. Kamuro immediately claims it, exposing that she was online, then calls him a liar and a “hentai.”
• Tatsuya oversleeps after lunch and arrives thirty minutes late to meet Karuizawa at Keyaki Mall. She is furious, but he apologizes by promising to pay for everything.
• During the shopping date, Tatsuya selects a beige cardigan for Karuizawa and compliments her when she tries it on. His casual physical affection—touching and arranging her hair—makes her noticeably flustered.
• He buys the cardigan, skirt, and secretly purchases a heart-shaped hair accessory as an additional gift.
• On the walk back to the dorms, Karuizawa rates his performance on the date. She deducts points for his lateness and for reasons of her own, but awards him ten bonus points because she genuinely enjoyed the day.

Character Developments

• Tatsuya Sakuya: His boredom leads him to actively seek interaction, and he treats the rental relationship playfully and confidently. Although irresponsible enough to oversleep, he compensates through generosity, attentiveness, and natural romantic gestures. His hidden purchase of the heart pendant suggests growing personal affection beyond the formal arrangement.
• Karuizawa Kei: She begins the chapter skeptical and annoyed, worried that Tatsuya is unreliable. However, she gradually becomes more comfortable and emotionally affected by his attention. Her embarrassment, flustered reactions, and final admission that she had fun reveal that she is beginning to enjoy their relationship.

• The chapter ends with Sakuya accepting her provocation and asking, “Can you bury me?”

Character Developments

• Tatsuya Sakuya: Reveals himself to be an exceptionally talented chess player, capable of defeating both a skilled club member and a national-level defensive specialist with ease. Despite his overwhelming ability, he remains lazy, playful, and primarily motivated by small personal rewards such as milk tea money. His confidence becomes more provocative when faced with Sakayanagi.
• Sakayanagi Arisu: Establishes herself as an intelligent, competitive observer who immediately recognizes Sakuya as an interesting opponent. Rather than treating him as an ordinary student, she views him as a rare and entertaining “toy.”

• Horikita Manabu: His presence and commanding speech reinforce his authority and prestige as Student Council president.
• The Chess Club president: Begins confident in his renowned defensive strategy but is psychologically shaken when Sakuya dismantles it. His defeat highlights the enormous gap between his skill and Sakuya’s.

Significant Themes

• Sakuya and Sakayanagi: Their first major exchange immediately becomes confrontational. Sakayanagi frames him as an entertaining challenge, while Sakuya responds with a provocative question that signals he welcomes the coming rivalry.

Chapter Summary: “Chess Meets Its Match, King vs. King”

Key Plot Points and Events

• Tatsuya Sakuya challenges Sakayanagi Arisu in a public chess match, provoking the surrounding students with his confidence and sharp remarks.
• Kamuro Masumi attempts to defend Sakayanagi and insult Sakuya, but he turns the challenge back on her by questioning whether she is capable of facing him herself. Embarrassed by her lack of chess ability, Kamuro falls silent.
• Sakayanagi intervenes and redirects the confrontation toward the chessboard, declaring that she will defeat Sakuya through the game rather than through words.
• Sakayanagi, playing White, opens with 1. e4, while Sakuya responds with the Sicilian Defense.
• The match quickly becomes far more advanced than the spectators can follow. Both players calculate many moves ahead, using precise attacks, defenses, and exchanges.
• Around the fortieth move, Sakayanagi launches a powerful attack against Sakuya’s king. Sakuya’s defensive structure appears vulnerable but proves extremely resilient.
• Sakuya secretly positions a knight where it threatens to decide the game. Sakayanagi recognizes that moving the knight to F3 would likely force her king into checkmate within a few moves.
• Instead of taking the winning continuation, Sakuya chooses a safer move that captures one of Sakayanagi’s advanced pawns. The attack loses momentum, and the players exchange most of the remaining pieces.
• The game ends with only kings and scattered pawns left, resulting in a draw. Sakayanagi realizes that Sakuya could likely have won but deliberately avoided doing so.
• Afterward, Sakayanagi invites Sakuya to lunch with her and Kamuro so she can question him about his crucial decision. Sakuya agrees, provided someone else pays, and Sakayanagi accepts responsibility for the bill.

Character Developments

• Tatsuya Sakuya: Demonstrates exceptional chess ability, remaining calm under pressure and matching Sakayanagi’s calculations. His decision to force a draw suggests that he is deliberately concealing his full strength or avoiding an outright victory. He also continues to use humor, false modesty, and apparent laziness to disguise his intentions.
• Sakayanagi Arisu: Confirms her status as an elite strategist and highly skilled chess player. She is able to understand Sakuya’s decisive opportunity, but his refusal to take it unsettles and intrigues her. Her interest in him grows stronger because she recognizes that his actions were intentional.
• Kamuro Masumi: Initially acts arrogantly while hiding behind Sakayanagi, hoping to use Sakayanagi’s reputation against Sakuya. His challenge exposes her insecurity and inability to play chess. By the end, she reluctantly follows Sakayanagi’s lead and joins the lunch invitation.

Significant Themes

• Control and influence: Sakayanagi controls Kamuro effortlessly, while Sakuya controls the pace and outcome of the game without openly revealing his intentions.

Chapter Summary: The Freeloader Queen’s Lunch, the Four Classes Under Control

Key Plot Points and Events

• At lunchtime, Sakayanagi Arisu, Tatsuya Sakuya, and Kamuro Masumi eat together in the cafeteria.
• Because Sakayanagi has limited mobility, Sakuya and Kamuro purchase the meals. Sakuya shamelessly orders an expensive double-pork-cutlet rice bowl using Sakayanagi’s student card, while Sakayanagi chooses sashimi and Kamuro buys only a cheap sandwich.
• Sakuya pressures Kamuro into buying him a drink by subtly threatening to expose evidence of her earlier theft. Kamuro cannot find the beer he requested and instead buys three bottles of Coke.
• Seeking revenge, Kamuro shakes Sakuya’s bottle intensely so that it will spray when opened. Sakuya notices her suspicious behavior and avoids opening it himself, tricking her into admitting that the bottle was shaken.
• The lunch conversation shifts to Sakuya’s placement in Class 1-D. Sakayanagi questions why someone of his apparent intelligence and ability belongs to the class regarded as the school’s “defective product depot.”
• Sakayanagi then assesses the condition of all four first-year classes and invites Sakuya to help lead Class 1-D to Class 1-A.
• Sakuya rejects the proposal, claiming that managing Class 1-D would be too troublesome and that he prefers to remain uninvolved as long as his own life is unaffected.

Character Developments

• Tatsuya Sakuya: Displays shamelessness, clever manipulation, and strong observational skills. He enjoys exploiting Kamuro’s fear of exposure and easily recognizes her revenge scheme. Although he pretends to be indifferent and lazy, his analysis and conversational control reveal considerable intelligence. He also deliberately lies about why he was placed in Class 1-D.
• Sakayanagi Arisu: Remains composed, perceptive, and socially dominant. She uses the lunch conversation to evaluate Sakuya, demonstrate her knowledge of the school’s political situation, and test whether he might become a rival or ally.
• Kamuro Masumi: Becomes increasingly irritated by Sakuya’s shameless behavior but also shows resourcefulness and a playful desire for revenge. Her attempt to sabotage his drink fails, reinforcing Sakuya’s advantage over her in their interaction.
• Class leaders: Though not physically present, Katsuragi, Ichinose, and Ryuen are characterized through Sakayanagi’s descriptions of their leadership styles.

Significant Themes

• Manipulation and hidden motives: Both Sakuya and Kamuro attempt to manipulate each other, but Sakuya’s awareness gives him the upper hand.
• Power beneath appearances: Sakuya presents himself as lazy and uninterested, while Sakayanagi recognizes that he may possess the ability to influence Class 1-D significantly.
• Leadership and social control: The four classes represent contrasting systems of control—strict management, trust and charisma, violence and intimidation, and disorder.
• Freedom versus responsibility: Sakuya refuses leadership because he values an easy, undisturbed life, even though he may have the ability to change his class’s position.
• Information as power: Sakayanagi’s detailed understanding of every class demonstrates her strategic reach, while Sakuya’s evasive answers show how carefully he conceals his own capabilities.

Important Character Interactions

• Sakuya and Kamuro engage in a hostile but increasingly playful exchange based on threats, errands, and attempted revenge.
• Sakuya and Sakayanagi converse as intellectual equals: she probes his motives, while he hides behind humor and deliberately implausible explanations.
• Sakayanagi uses her discussion of the four classes to assert her authority and indirectly challenge Sakuya to reveal whether he is capable of leadership.
• Sakuya’s refusal leaves open the possibility that his apparent neutrality is temporary rather than genuine.

Chapter Summary

Key Plot Points and Events

• After lunch, Tatsuya Sakuya, Sakayanagi Arisu, and Kamuro Masumi part ways on the Keyaki Mall skybridge.
• Sakayanagi calls their lunch and earlier encounter a “warm-up match” and provocatively proposes a personal wager: if Tatsuya loses their next contest, he must become her “exclusive toy.” Tatsuya jokes that, if he wins, she should do his homework for three years. Sakayanagi laughs and leaves, signaling her interest in him as a future opponent.
• Back in Class 1-D, Tatsuya finds the classroom in its usual chaotic state: students are playing, sleeping, gossiping, littering, and behaving carelessly.
• Horikita Suzune questions Tatsuya about his lunch with Class 1-A. He explains that Sakayanagi treated him and shares her assessment of the four classes:
  • Class 1-A is disciplined and rule-abiding.
  • Class 1-B is united through Ichinose Honami’s leadership and mutual trust.
  • Class 1-C is controlled by Ryuen Kakeru through violence but remains functional.
  • Class 1-D is viewed as a “Gathering Place of Defective Products.”
• Tatsuya bluntly reinforces Sakayanagi’s judgment by pointing out Class 1-D’s constant lateness, truancy, sleeping, phone use, and general lack of discipline.
• Horikita becomes furious because, despite the insult, she cannot deny that the criticism is accurate. She attacks Tatsuya with a chop to the neck and then escalates by pulling out a compass, earning the joking image of the “Compass Demon.”

Character Developments

• Tatsuya Sakuya: Demonstrates confidence, emotional composure, and a willingness to provoke others with uncomfortable truths. His connection with Sakayanagi becomes more significant, suggesting a competitive relationship with personal stakes. He also shows that he understands the broader class hierarchy and is willing to share information with Horikita.
• Sakayanagi Arisu: Reveals a playful but dangerous interest in Tatsuya. Her “exclusive toy” wager reflects both her provocative personality and her desire to establish control or intimacy through competition.
• Kamuro Masumi: Reacts with visible discomfort to Sakayanagi’s outrageous proposal, highlighting how extreme Sakayanagi’s behavior appears even to her ally.
• Horikita Suzune: Her pride and ambition are wounded by Sakayanagi’s evaluation of Class 1-D. Although she wants to rise to Class 1-A and prove herself, she is forced to confront the possibility that her classmates’ behavior supports the school’s low opinion of them. Her anger toward Tatsuya exposes her sensitivity beneath her normally controlled exterior.
• Class 1-D: Is characterized as undisciplined, immature, and lacking the cohesion or standards of the other classes.

Significant Themes

• Truth versus emotional comfort: Tatsuya’s statement that “lies don’t hurt; the truth is the sharp blade” captures the chapter’s central idea. Horikita is not enraged merely because Sakayanagi insults the class; she is shaken because the criticism is difficult to refute.
• Class identity and social judgment: The four classes are defined by their dominant qualities—discipline, trust, violence, and incompetence. The chapter emphasizes how reputation and collective behavior shape a class’s prospects.
• Pride and ambition: Horikita’s desire to reach Class 1-A clashes with the reality of being placed in Class 1-D. Her reaction shows how deeply she links her self-worth to excellence and her rivalry with her brother.
• Competition and control: Sakayanagi’s proposed wager transforms a casual meeting into a psychological contest, while Tatsuya’s exchanges with both Sakayanagi and Horikita show him navigating power through teasing, information, and provocation.
• Comedy amid tension: The absurdity of Sakayanagi’s wager and Horikita’s exaggerated “Compass Demon” response lighten an otherwise serious confrontation.

Character Interactions

• Tatsuya and Sakayanagi: Their conversation is flirtatious, mocking, and competitive. Sakayanagi openly challenges him, while Tatsuya maintains a relaxed attitude and counters her proposal with humor.
• Tatsuya and Horikita: Horikita interrogates him about Class 1-A, but the exchange becomes a harsh critique of Class 1-D. Tatsuya deliberately provokes her by repeating Sakayanagi’s assessment and forcing her to face the class’s shortcomings.
• Horikita and Class 1-D: Though she considers herself superior to her classmates, Horikita is emotionally affected by their poor behavior because it undermines her goal of advancing to Class 1-A.
• Class 1-D students: Their carefree interactions—Sudo’s failed paper-ball shot, Ike and Yamauchi’s teasing, and the general classroom disorder—provide the evidence behind Sakayanagi’s condemnation.

Chapter Summary

Key Plot Points and Events

• During an Advanced Mathematics lesson, the teacher explains indefinite integrals, emphasizing the importance of including the differential (dx) and the constant (C).
• To test the class, he writes two problems on the board: (\int \cos x,dx) and (\int(2x+\cos x),dx).
• He wakes Yamauchi Haruki, who is sleeping, and asks him to answer. Still groggy, Yamauchi mistakes the integral symbol for a “crowbar,” causing Class 1-D to burst into laughter.
• The teacher then calls on Tatsuya Sakuya. Tatsuya correctly answers both problems—(\sin x+C) and (x^2+\sin x+C)—restoring the teacher’s faith that the class contains capable students.
• During the break, Horikita Suzune comments on Tatsuya’s correct answers and jokes that she expected him to say something absurd like Yamauchi.
• Kushida Kikyou joins them and discusses friendship and a psychological survey the students have just received.
• Tatsuya and Horikita are summoned to the faculty office by their homeroom teacher, Chabashira Sae.
• Chabashira explains that the school requires an annual psychological assessment. She gives them QR codes and instructs them to complete a fifty-question test in ten minutes.
• The questions appear to evaluate morality, loyalty to the class, personal priorities, and social adaptability rather than ordinary mental health. Tatsuya realizes the assessment is actually part of Advanced Nurturing University’s broader evaluation of students’ values and behavior.

Character Developments

• Tatsuya Sakuya: Demonstrates strong mathematical ability and attentiveness despite appearing somewhat detached. His answers reveal competence, while his response to Kushida suggests he has a complicated or balanced attitude toward forming friendships.
• Horikita Suzune: Remains cold and observant, teasing Tatsuya while also acknowledging his abilities. Her immediate, efficient response to the psychological test reflects her disciplined personality.
• Yamauchi Haruki: Is portrayed as inattentive and comically foolish, falling asleep in class and confusing the integral symbol with a crowbar.
• Kushida Kikyou: Displays her usual sociable nature by joining the conversation and asking Tatsuya about friendship. Her interest in the psychological survey hints at her curiosity about others’ personalities.
• Chabashira Sae: Appears professional and composed, but her explanation of the assessment reveals that the school closely monitors students’ psychological and social traits.

Significant Themes

• Academic competence versus laziness: Tatsuya’s correct answers contrast sharply with Yamauchi’s sleeping and foolish response, highlighting the differing abilities within Class 1-D.
• Appearance and hidden capability: Although Tatsuya seems quiet and possibly distracted, he is capable and observant. The chapter suggests that students may not be what they initially appear to be.
• Social relationships and friendship: The conversation between Tatsuya, Horikita, and Kushida explores whether people genuinely want friendship and how personal relationships may be complicated by conflicting feelings.
• Institutional surveillance and evaluation: The psychological assessment shows that the school evaluates more than grades. It studies students’ morals, loyalty, adaptability, and decision-making, reinforcing the competitive and controlled nature of the academy.
