• The girls immediately raise concerns about hygiene, particularly the school-provided makeshift cardboard toilet. Shinohara strongly objects to using it, while Ike dismisses her concerns and argues that points are more important.
• Chabashira interrupts the brewing conflict and emphasizes that the class must first choose a leader, whose role is crucial to the exam.
• A timed task appears, requiring the students to occupy the island’s 20 strongholds and check in at them repeatedly within the time limit.
• Suzuki Tsubame volunteers to become the leader. His Key Card is already registered to him, and no one objects.
• Suzuki races through the forest, occupying all 20 strongholds in approximately 65 minutes. The locations include a clearing, a steep slope, a cave, and areas near streams. He notices that one stronghold may correspond to the location used by Class D in the original story.
• After completing the circuit, Suzuki cleans himself up at a stream before returning to the class campsite.
• Upon his return, he finds the class divided over Shinohara’s refusal to use the makeshift toilet. Her friends have gradually abandoned their support after Karuizawa Kei refused to help her, leaving Shinohara isolated.

Chapter Summary: “Uninhabited Island (2)”

Key Plot Points and Events

• The class spends nearly an hour arguing over whether to use Exam Points to purchase an additional toilet. Ike objects, believing the school-provided cardboard-like toilet should be sufficient and that points should be conserved.
• Suzuki Tsubame resolves the argument by pointing out that the class lacks adequate shelter, food, bathing facilities, and other necessities. He also reminds everyone that a student withdrawing from the exam would cost thirty Exam Points, making the toilet relatively inexpensive by comparison.
• He emphasizes the importance of privacy and hygiene during the seven-day exam, especially since the tents cannot serve as bathrooms or bathing areas.
• Kushida supports Suzuki’s reasoning, though she initially hesitates because she worries about losing popularity with the boys. Ike immediately agrees once Kushida speaks, prioritizing her comfort over his own desire to save points.
• Karuizawa and the other girls also support the purchase. The class ultimately spends points on two additional tents, two toilets, and several iron pots, while relying on the school’s unlimited plastic bags for water storage.
• Afterward, the class divides responsibilities: the boys build the tents and toilets, while the girls collect firewood. Suzuki and the sick Horikita remain seated and supervise.
• Horikita has a slight fever, and Suzuki checks on her. She later asks about his difficult journey to check the class bases and whether he thought about other girls such as Sakayanagi or Sakura.
• Suzuki reassures Horikita that his feelings for her have remained constant. He compares her favorably to everyone else and embraces her openly, revealing their mutual romantic closeness in front of the class.

Character Development

• Suzuki Tsubame: Demonstrates practical leadership and sound judgment by prioritizing necessities over excessive point conservation. He also shows deep emotional commitment to Horikita, openly affirming that his feelings for her have never changed.
• Horikita Suzune: Though physically unwell, Horikita remains attentive to Suzuki and reveals jealousy or insecurity by asking whether he thought about other girls. Her willingness to accept his embrace publicly suggests increasing trust and comfort in their relationship.
• Ike: Initially stubborn and emotionally attached to conserving points, Ike changes his position after realizing the toilet is necessary and after Kushida supports the purchase. His willingness to give in for Kushida exposes both his devotion and the emotional pain caused by her rejection.
• Kushida: Acts cautiously to preserve her image, but ultimately supports Suzuki’s practical argument. Her influence over Ike remains strong.
• Karuizawa: Continues to rely on Suzuki’s support and confidently backs the purchase, while her lack of progress on the task remains notable.
• The Class: Becomes more cooperative after the dispute and organizes itself into practical work groups.

Significant Themes

• Practicality versus idealism: The class wants to conserve Exam Points, but survival requires spending resources on basic necessities.
• Leadership and persuasion: Suzuki resolves conflict through calm reasoning rather than force, demonstrating effective leadership.
• Hygiene, privacy, and dignity: The toilet symbolizes the importance of maintaining personal boundaries and normal standards of living even in harsh conditions.

• Kushida’s support changes Ike’s mind, highlighting his strong feelings for her.
• Karuizawa and the girls reinforce the decision, helping achieve unanimous approval.

• The boys’ stunned reaction to the couple’s public display provides a humorous conclusion to the chapter.

Chapter Summary: Uninhabited Island (3)

• Dinner planning: As the tent construction nears completion, Hirata asks Suzuki Tsubame how the class should handle dinner. Suzuki proposes letting all thirty-nine students decide whether to buy prepared meals, raw ingredients, or only seasonings and forage for food. The class ultimately chooses to purchase basic ingredients—rice, eggs, oil, and seasonings—for forty points, judging this the most practical and economical option for seven days.
• Horikita’s worsening illness: Horikita wakes when Hirata approaches, revealing that she is a light sleeper and still suffering from a cold. Suzuki notices that her condition appears worse than before. He helps her sit up, brings her warm water, and personally holds the cup to her lips. Although Horikita initially seems embarrassed and believes she can manage by herself, she accepts his care and quietly enjoys the feeling of being looked after. Their interaction shows growing trust and intimacy.
• Ayanokoji’s reconnaissance: Ayanokoji returns after scouting the other classes. He reports that:
  • Class C is holding an extravagant beach party and expects to spend about one hundred points.
  • Class B has chosen the same economical strategy as Class D, buying basic ingredients.
  • Class A is staying in a guarded cave, preventing him from learning more.
    Suzuki compares these developments with the original course of events and notes that Sakayanagi remains the major unpredictable variable. He also suspects that Chabashira assigned Ayanokoji to assist because she does not fully trust him to manage the class alone.
• Foraging and class activities: Suzuki gives Ike bags of wild vegetables and raspberries he gathered while checking the island’s locations. Ike identifies them as longevity vegetables, shepherd’s purse, bracken, and raspberries, becoming enthusiastic about their usefulness. Suzuki instructs Ike to find students who can identify and sort the plants. He does not expect the class to become self-sufficient; the activity is mainly meant to occupy everyone during their seven-day stay.
• Character developments and interactions: Suzuki acts increasingly as the class’s practical leader, balancing economy, morale, and individual needs. Hirata continues to support cooperative decision-making. Ayanokoji contributes discreetly through reconnaissance, while Suzuki rewards him jokingly with a “Kun Egg,” creating a small moment of humor. Ike’s enthusiasm reveals his usefulness in outdoor and food-related matters. Suzuki’s attentive care for Horikita further deepens their relationship.
• Themes: The chapter emphasizes cooperation, resource management, leadership, and the contrast between classes’ spending strategies. It also highlights dependence and trust, especially through Suzuki and Horikita’s interaction, while showing how the students use work and foraging to maintain morale on the isolated island.
• Ending: By nightfall, Class D’s occupied checkpoint shows roughly fifteen minutes remaining on its timer, indicating that the class secured the location around 12:30 p.m. and has maintained control for nearly eight hours.

Chapter Summary

• As Suzuki Tsubame prepares to leave the cave at night, Hirata offers to accompany him. Suzuki refuses, saying Hirata should stay with the group and that their school-issued watches provide tracking and emergency-rescue functions. He also doesn’t want to be slowed down or have to protect Hirata.
• Kushida and the other girls offer Suzuki some of their leftover rice balls for the journey. He initially refuses because none of them have eaten any, and he doesn’t want to accept food as charity.
• To show their sincerity, Kushida, Sakura, Haruka, and Matsushita each take a small bite from a rice ball before offering the bag again. Haruka teases Suzuki for resisting, and he eventually accepts the food.
• Suzuki notices Horikita standing apart and goes to speak with her. She gives him something and tells him to be careful, then starts to return to camp. He stops her, reminding her that she is still a patient.
• Horikita takes a small bite from one of the rice balls in his bag and leaves without explanation. Suzuki is left puzzled, wondering how she could have known what the others were doing from so far away.

Character Developments and Interactions

• Suzuki remains independent and practical, declining Hirata’s help but accepting the girls’ food once they make clear it is offered in friendship rather than pity.
• Hirata shows concern for Suzuki, while respecting his decision to stay behind.
• Kushida and the other girls act together to encourage Suzuki and express their care through the shared food.
• Horikita shows concern in her restrained way, warning Suzuki to be careful and unexpectedly joining the girls’ gesture. Her actions leave Suzuki wondering what she was thinking.

Significant Themes

• Mutual care and solidarity: The rice balls become a small but meaningful sign of the group’s support.
• Independence and trust: Suzuki prefers to handle the dangerous trip alone, but gradually accepts others’ concern.
• Unspoken understanding: Horikita’s quiet actions suggest a connection or awareness that Suzuki cannot quite explain.

Chapter Summary: Uninhabited Island (5)

Key Plot Points and Events

• Suzuki Tsubame rushes through the jungle at night to occupy the next checkpoint, despite wondering how another person managed to reach the area so quickly.
• He successfully claims the first checkpoint for Class D and waits cautiously for the next update.
• Suzuki detects an exceptionally stealthy presence approaching. Using his heightened awareness and the Presence Regulator, he discovers Hoshinomiya Chie, an accompanying teacher, hiding near the checkpoint.
• Hoshinomiya claims she is merely taking a walk and checking whether the students are taking the exam seriously. Suzuki notices that she has no visible watch or other way to conceal one, suggesting that she may be violating the rules by leaving her assigned checkpoint.
• Rather than argue, Suzuki warns her indirectly that their interests may conflict and leaves to continue the exam. His calm, perceptive attitude makes Hoshinomiya wary of him.
• Suzuki proceeds through four additional checkpoints without incident. The island is unusually quiet until he reaches the sixth checkpoint.
• There, he finds Ichinose Honami and Shiranami Chihiro waiting together. Chihiro tries to persuade Ichinose to lend her a jacket despite the summer heat, apparently using coldness as an excuse.
• Suzuki observes them from hiding before revealing himself. Chihiro instinctively retreats behind Ichinose, while Ichinose remains polite and composed.
• Suzuki teases Shiranami about their former acquaintance, highlighting her lingering fear and awkwardness around him.
• Ichinose worries that Suzuki may be alone and therefore exposing himself as a class leader, which would invalidate his class’s accumulated points. Suzuki responds confidently by presenting his identification card for her inspection.

Character Developments

• Suzuki Tsubame: Demonstrates speed, vigilance, stealth detection, and strong situational awareness. He remains calm when confronting Hoshinomiya and shows a pragmatic attitude toward alliances, prioritizing his class’s interests. His teasing manner also reveals confidence in his control of the situation.
• Hoshinomiya Chie: Her playful, carefree persona briefly gives way to caution and suspicion after Suzuki notices her suspicious behavior. She recognizes that he is more perceptive and threatening than expected.
• Ichinose Honami: Continues to display her characteristic kindness and reluctance to reject others harshly. Even while handling Chihiro, she remains considerate. She is also alert to the exam’s strategic dangers and immediately worries about Suzuki’s possible exposure.
• Shiranami Chihiro: Acts dependent and timid around Ichinose, seeking comfort and protection. Her nervous reaction to Suzuki suggests that she remains intimidated by their previous encounter and avoids direct interaction with him.

Significant Themes

• Trust versus self-interest: Suzuki emphasizes that temporary cooperation is subordinate to personal and class interests, reflecting the competitive nature of the exam.
• Observation and deception: Characters conceal their intentions, identities, and movements. Suzuki’s ability to read behavior gives him an advantage over both Hoshinomiya and the students.
• Power beneath appearances: Hoshinomiya’s lazy, playful exterior hides vigilance, while Ichinose’s gentle demeanor coexists with strategic awareness. Suzuki likewise masks his sharpness behind calm, casual speech.
• Fear and lingering consequences: Shiranami’s avoidance of Suzuki shows how past experiences continue to affect present behavior.
• Rules and exploitation: Hoshinomiya’s unexplained presence outside her checkpoint raises questions about how the exam’s rules can be bent or used for strategic purposes.

Character Interactions

• Suzuki and Hoshinomiya engage in a tense, indirect confrontation. He exposes the suspicious nature of her actions without openly accusing her, and she becomes more guarded.
• Suzuki, Ichinose, and Shiranami meet at the sixth checkpoint. Ichinose acts as a mediator and protector for the nervous Shiranami.
• Suzuki deliberately provokes Shiranami by referring to their past relationship, while she responds with visible discomfort.
• Ichinose’s concern over Suzuki’s possible class-leader exposure contrasts with Suzuki’s relaxed confidence as he offers his ID card openly.

Chapter Summary: “Occupation”

Key Plot Points and Events

• Ichinose and Shiranami encounter Suzuki Tsubame, who openly reveals that he is Class D’s leader by showing his identity card.
• Ichinose immediately suspects that Suzuki has some hidden advantage, since revealing his identity should normally put him at serious risk. Rather than challenge him and expose their own leader’s identity, she allows him to occupy the outpost.
• Suzuki successfully checks in and extends Class D’s occupation time to nearly eight hours before moving on to capture more outposts.
• Near Class A’s camp, Katsuragi and Yahiko set up a careful ambush at an important cave outpost. Katsuragi refuses to block the cave entrance because doing so might violate the school’s rules concerning the use of other classes’ outposts.
• Katsuragi reasons that Suzuki must eventually appear to refresh the outpost timers, allowing Class A to identify and track him. He emphasizes that the contest depends more on patience and planning than direct confrontation.
• Despite watching the entrance continuously, Katsuragi and Yahiko fail to see Suzuki arrive. When they finally check the outpost, they discover that Class D has already occupied it.
• The unexplained occupation leaves both men stunned. Katsuragi realizes that Suzuki has somehow bypassed their surveillance, while Suzuki continues capturing the remaining outposts.

Character Developments

• Ichinose: Demonstrates her intelligence and strategic caution. Although naturally kind, she does not blindly trust Suzuki. She chooses to surrender the outpost in order to avoid exposing her own leader and to test whether Suzuki’s identity card is genuine.
• Suzuki Tsubame: Becomes increasingly mysterious and confident. He openly exploits Ichinose’s kindness while showing no fear of revealing his identity. His ability to occupy the cave outpost unseen establishes that he possesses an unusual method or advantage.
• Shiranami: Reacts emotionally and impulsively, unable to understand why Ichinose would surrender such an important outpost. Her response contrasts with Ichinose’s calm strategic thinking.
• Katsuragi: Is portrayed as disciplined, rational, and highly strategic. He carefully considers the rules and refuses to act recklessly, but his confidence in his surveillance plan is shaken when Suzuki defeats it.
• Yahiko: Relies heavily on Katsuragi’s judgment. He initially favors a more direct approach but follows Katsuragi’s instructions and is left bewildered by the unexplained failure.

Significant Themes

• Strategy versus force: Characters avoid direct conflict because revealing a leader’s identity can be more damaging than losing an individual outpost.
• Patience and planning: Katsuragi stresses that success depends on anticipating opponents and waiting for the right opportunity.
• Deception and hidden abilities: Suzuki’s open disclosure of his identity and his unseen occupation of the cave outpost suggest that appearances are misleading and that he has a concealed advantage.
• Trust and manipulation: Ichinose’s kindness allows Suzuki to gain the outpost, while Suzuki subtly uses her concern about bullying and isolation to influence her decision.
• Limits of rational planning: Katsuragi’s careful plan fails despite being logically sound, showing that strategy cannot succeed without accounting for unknown methods.

Character Interactions

• Ichinose and Suzuki engage in a polite but tense exchange in which Suzuki pressures her through emotional manipulation, while Ichinose responds by making a calculated strategic concession.
• Shiranami challenges Ichinose’s decision, but Ichinose quietly restrains and reassures her.
• Katsuragi instructs Yahiko to remain hidden and patient, teaching him the importance of rules, timing, and observation.
• The chapter ends with Katsuragi and Yahiko united in confusion after Suzuki outmaneuvers them, intensifying the mystery surrounding Class D’s leader.

Chapter Summary: “Betrayal”

Key Plot Points and Events

• He wakes before dawn to complete more check-ins, showing that he is maintaining an intense and ambitious strategy despite his growing exhaustion.
• Kamuro secretly infiltrates Class D’s camp and confronts Suzuki, confirming that she has discovered he is the class leader.
• Suzuki immediately realizes that Sakayanagi sent Kamuro to investigate him, demonstrating his awareness of Class A’s methods.
• Kamuro reveals that Sakayanagi has identified Yahiko as Class A’s leader. Suzuki accepts the information without surprise and predicts that Class A will “lose everything this time.”
• Upon returning to camp, Suzuki learns that Koenji never came back after the previous night’s roll call. He assumes Koenji has withdrawn from the exam and tells the others not to worry about it.

Character Developments

• Suzuki Tsubame: Becomes increasingly established as Class D’s hidden leader. He is highly observant, emotionally composed, and confident in his own plans. His early-morning exhaustion also reveals the physical and mental cost of his strategy. He views Sakayanagi as someone who treats the school as a personal game rather than genuinely supporting her class.
• Kamuro: Shows initiative by secretly investigating Class D, but her pride is easily wounded by Suzuki’s dismissive attitude. Although she acts as Sakayanagi’s messenger, she considers herself a victim of Sakayanagi’s betrayal rather than a willing conspirator.
• Sakayanagi: Remains an unseen but influential strategist. Her quick response to Suzuki’s activity demonstrates her intelligence and vigilance, while her willingness to reveal Class A’s leader suggests she is prioritizing personal goals over class loyalty.
• Hirata: Feels responsible for failing to monitor Koenji, reflecting his dependable and conscientious nature.
• Koenji: His disappearance suggests that he has withdrawn from the exam, reinforcing his independence and apparent lack of commitment to Class D’s collective effort.

Significant Themes

• Betrayal and divided loyalties: The chapter centers on Sakayanagi’s betrayal of her class and Kamuro’s complicated position as both accomplice and victim.
• Hidden identities and strategic deception: Suzuki’s secret role as Class D’s leader contrasts with Kamuro’s covert surveillance and Sakayanagi’s indirect manipulation.
• Individual ambition versus class interests: Suzuki’s aggressive strategy, Sakayanagi’s personal motives, and Koenji’s possible withdrawal all highlight the conflict between personal goals and group success.
• Composure and psychological control: Suzuki’s unemotional responses frustrate Kamuro and reveal that maintaining control over information and reactions is itself a form of power.
• Exhaustion and sacrifice: Suzuki’s pre-dawn work shows that success in the exam requires relentless effort, even when the rewards are uncertain.

Character Interactions

• Suzuki and Kamuro: Their exchange is a tense but understated battle of intelligence. Kamuro tries to expose Suzuki and deliver Sakayanagi’s information, while Suzuki immediately recognizes her motives and treats the encounter casually. His teasing about her grades further irritates her.
• Suzuki and Sakayanagi: Though Sakayanagi never appears directly, their strategic rivalry dominates the chapter. She attempts to monitor and influence him through Kamuro, while Suzuki dismisses her methods and predicts Class A’s defeat.
• Suzuki, Hirata, Horikita, and Ayanokoji: The three classmates confront Suzuki upon his return, and Hirata informs him of Koenji’s absence. Their interaction emphasizes Suzuki’s leadership role and the uncertainty created by Koenji’s disappearance.

Chapter Summary: “Camp”

Key Plot Points and Events

• During roll call, Chabashira announces that Koenji has returned to the cruise ship because of physical discomfort and applied to withdraw from the exam, costing Class D thirty Exam Points.
• Class D reacts angrily, especially Sudo, who condemns Koenji’s selfishness. Suzuki Tsubame deliberately provokes the class by making sarcastic remarks about Koenji’s “beauty sleep” and the cruise ship’s air conditioning, successfully intensifying the group’s resentment.
• After roll call, Horikita asks Ayanokoji and Suzuki Tsubame to help investigate the other classes’ camps. She believes Ayanokoji may have missed important information during his previous scouting.
• The group first observes Class C, which appears to be treating the exam like a vacation. Their camp is filled with umbrellas, lounge chairs, grills, jet skis, snacks, and other expensive supplies.
• Suzuki notices that Ryuen has a walkie-talkie nearby, suggesting that Class C’s relaxed behavior may be deceptive and that they are preparing to make a move later.
• They then visit Class B’s camp, which is orderly, peaceful, and well-managed. The students cooperate efficiently and seem happy despite the difficult conditions.
• Suzuki internally reflects that Class B’s apparent unity is fragile because it depends heavily on Ichinose’s leadership. He believes that weakening Ichinose could cause the entire class to collapse.
• Horikita decides they should enter Class B’s camp to observe everyone’s reactions and identify anyone acting suspiciously.
• Kanzaki confronts them, demanding to know why they are there. The exchange becomes awkward because neither Ayanokoji nor Suzuki immediately takes the lead in speaking.
• Ichinose approaches and warmly greets Suzuki, easing the tension. Suzuki honestly explains that Horikita brought him there to see whose reactions seemed unusual.

Character Developments

• Koenji further establishes his reputation as an individualist who prioritizes himself over Class D’s success. His withdrawal creates a significant disadvantage and fuels hostility toward him.
• Sudo shows his strong sense of class loyalty and frustration with people who endanger the group. His emotional reaction reflects the growing pressure of the exam.
• Suzuki Tsubame demonstrates his skill at manipulating group emotions through sarcasm and provocation. He also displays sharp observational ability, correctly suspecting that Class C’s carefree atmosphere hides a strategy.
• Horikita remains proactive and suspicious. Rather than accepting appearances, she insists on personally investigating the other classes and testing their reactions.
• Ayanokoji serves as the practical guide and observer, accompanying Horikita while remaining emotionally detached and allowing her to direct the investigation.
• Ichinose reinforces her role as Class B’s emotional center and leader. Her calm, friendly approach immediately reduces the tension caused by the intruders.
• Kanzaki appears more defensive and vigilant than the rest of Class B, suggesting either heightened suspicion or possible unease within the class.

Significant Themes

• Individualism versus collective responsibility: Koenji’s withdrawal shows how one person’s choices can harm an entire group in a competitive exam.
• Manipulation and social influence: Suzuki’s deliberately provocative comments reveal how easily group anger can be directed, especially under stressful conditions.
• Appearances versus reality: Class C’s luxurious celebration may conceal an active plan, while Class B’s perfect harmony may mask an underlying weakness.
• Leadership and dependence: Class B’s stability appears strongly tied to Ichinose, raising questions about whether its unity can survive without her influence.
• Surveillance and strategy: The students constantly gather information by observing camps, equipment, behavior, and suspicious reactions rather than trusting surface impressions.

Important Character Interactions

• Sudo and the rest of Class D unite in condemning Koenji, while Suzuki intentionally heightens their anger.
• Horikita, Ayanokoji, and Suzuki work together as an investigation team, though Horikita’s impulsive decisions contrast with the others’ more restrained attitudes.

• Kanzaki and the Class D group clash when he challenges their presence in Class B’s camp.
• Ichinose and Suzuki share a warmer interaction, with Ichinose recognizing him and responding to his blunt explanation with her characteristic friendliness.

Summary

Key plot points and events

Suzuki Tsubame bluntly reveals that Horikita instructed them to observe which Class B member reacted most unusually. His careless remark creates an awkward confrontation at Class B’s camp. Ichinose attempts to smooth things over, while Kanzaki and the other students demand that the visitors leave. Suzuki, Horikita, and Ayanokoji withdraw without escalating the situation. Once away from the camp, Suzuki criticizes Class B as dependent “parasites,” arguing that its members rely entirely on Ichinose while avoiding responsibility and conflict.

Character developments

• Suzuki Tsubame demonstrates sharp observational skills and quickly identifies the weakness in Class B’s structure. He remains calm and detached during the confrontation, though his harsh private judgment reveals his lack of sympathy for Class B. His suggestions for spreading rumors also show a willingness to use underhanded tactics, albeit with an absurd sense of humor.
• Horikita recognizes the strategic value of exploiting Class B’s internal weaknesses and becomes open to provoking conflict between its members. She is embarrassed and frustrated by Suzuki’s ridiculous examples, but her willingness to consider manipulation reflects her growing pragmatism.
• Ayanokoji remains quiet and observant, following Suzuki and Horikita’s lead without revealing his own thoughts.
• Ichinose continues to act as a gentle mediator, trying to protect both her classmates and the visiting students. Her kindness also makes her vulnerable to being exploited by her classmates.
• Kanzaki displays stronger instincts and greater awareness than the rest of Class B, immediately sensing that Suzuki is dangerous and urging Ichinose to remove the visitors.

Significant themes

• Dependence versus responsibility: Class B presents itself as united, but Suzuki argues that its unity is built on everyone relying on Ichinose rather than sharing leadership or burdens.
• The burden of leadership: Ichinose functions as a shield for her classmates, absorbing pressure while they remain passive. The chapter foreshadows that Class B may collapse if she can no longer maintain stability.
• Strategy and manipulation: Horikita begins considering psychological warfare and rumor-spreading as legitimate tools against a rival class. The discussion also highlights the importance of believable information when manipulating people.
• Appearances versus reality: Class B appears harmonious and cooperative, but Suzuki sees fear, passivity, and hidden contradictions beneath the surface.

Character interactions

Suzuki’s careless disclosure puts Ichinose in an uncomfortable position and prompts Kanzaki and the others to drive Class D away. Afterward, Horikita questions Suzuki about his observations, leading to an analysis of Class B’s weaknesses. Horikita then suggests accelerating internal conflict, while Suzuki proposes deliberately false rumors. His exaggerated examples frustrate Horikita, who concludes that his ideas are too nonsensical to be useful and abandons the immediate plan.

Chapter Summary: “Playing the Victim”

• Horikita reports that Class A is tightly guarding its camp and preventing other classes from observing it. She suspects Class C may have completed a secret exchange with Class A.
• Suzuki theorizes that Class C’s apparent pursuit of Exam Points is a distraction. He predicts that Class C will withdraw from the island and return to the cruise ship that afternoon.
• Suzuki confronts Ibuki, teasing her about her injuries and provoking her anger. She accuses him of lying because he technically deleted only one portion of the maid-outfit video he had promised to erase.

Chapter Summary

• Ibuki is confronted about Ryuen’s operation. Suzuki Tsubame reveals that Ibuki had a camera in her backpack and had buried the walkie-talkie before the operation began. Ibuki is alarmed, suspecting that Kaneda may have leaked the plan. Tsubame asks whether she will continue down her current path or change course, but her response is left unresolved.
• The island strategy shifts. By the fifth day, Tsubame’s forceful takeover of strongholds has discouraged the other classes from competing for them. Instead, they conserve points by gathering supplies on the island.
• Shiraishi Asuka’s perspective is introduced. She reflects that she entered the school as an Observer, carrying out Teacher Shirogane’s expectations and carefully acting in her conversations. When she injures her ankle, however, she briefly wishes she could set aside that role and simply be an ordinary student.
• Tsubame helps the injured Asuka. He notices her ankle and offers assistance. Though her instincts tell her to keep her distance, she accepts. He unexpectedly carries her in a princess hold toward the Class A camp. Embarrassed by the closeness, Asuka protests, but she gradually relaxes and finds comfort in his warmth. Near camp, she asks him to put her down, worried about gossip and how the sight might affect her mission.

Character Developments and Interactions

• Ibuki is shaken by Tsubame’s knowledge and begins questioning whether her loyalty to the operation still makes sense.
• Suzuki Tsubame continues to take control of situations—first by confronting Ibuki directly, then by decisively helping Asuka. His calm, considerate manner contrasts with his commanding approach to strategy.
• Shiraishi Asuka experiences a rare lapse in her disciplined Observer persona. Tsubame’s kindness brings out her uncertainty, embarrassment, and desire for ordinary human connection.
