• On the bus to school, Hoshinomiya Rinyu recognized Koenji, Ayanokoji Kiyotaka, Horikita Suzune, and Kushida Kikyo, then gave his seat to an elderly woman and introduced himself to Kushida.
• After arriving at school, Hoshinomiya spoke with Horikita and found that he had been assigned to Class 1-A.
• Hoshinomiya took the empty seat beside Sakayanagi Arisu, introduced himself, and observed the class’s opposing groups led by Sakayanagi and Katsuragi Kohei.
• Mashima Tomoya explained that students received 100,000 points each month and that points served as the school’s currency.

Chapter Summary: “To... To Me, Is It?”

Key Plot Points and Events

• In Class A, Katsuragi Kohei proposes that students introduce themselves in student-number order to improve cooperation and task assignments.
• Sakayanagi Arisu dismisses introductions as childish and meaningless, arguing that brief statements cannot reveal a person’s true value. Her challenge creates tension and silence in the classroom.
• Hoshinomiya Rinyu, who has been quietly observing the dispute, falls asleep during the confrontation. Morishita Ai wakes him by throwing a pellet of kneaded eraser at the back of his head.
• Still half-asleep, Rinyu assumes it is his turn and gives a simple self-introduction. His obliviousness causes the class to erupt in laughter.
• Rinyu remains unusually calm rather than embarrassed, saying he will wash his face. His reaction intrigues Sakayanagi.
• Outside, Rinyu washes his face, reflecting briefly on a dream about his grandfather, then buys a black coffee and a latte from a vending machine.
• Sakayanagi approaches him and invites him to walk to the auditorium together for the entrance ceremony. Rinyu gives her the extra coffee, which she accepts as a thoughtful “meeting gift.”
• As they leave, Sakayanagi begins asking whether Rinyu knows the school’s rules.

Character Developments

• Sakayanagi Arisu: Establishes herself as intellectually arrogant, perceptive, and dismissive of superficial social rituals. However, Rinyu’s strange composure and apparent lack of embarrassment genuinely amuse and interest her. She compares him to a mysterious person from her past and takes the initiative to spend time with him.
• Hoshinomiya Rinyu: Appears sleepy, detached, and unconventional, yet observant enough to follow the situation around him. His calm response to public embarrassment suggests emotional resilience or unusual indifference. He also shows casual thoughtfulness by offering Sakayanagi the extra coffee.

• Morishita Ai: Quietly participates in the classroom dynamic by waking Rinyu, contributing to the comedic disruption.

Significant Themes

• Superficial impressions versus true value: The argument over introductions raises the question of whether brief self-presentations can reveal a person’s real abilities or character.
• Individuality and nonconformity: Rinyu’s sleeping through the conflict and responding without shame make him stand out from the ambitious, status-conscious students.
• Curiosity and hidden identities: Sakayanagi senses that Rinyu resembles someone mysterious, implying that both his background and potential may be deeper than they initially appear.
• Social tension beneath politeness: Although the characters speak calmly, the classroom debate exposes competing approaches to authority, cooperation, and class leadership.

Character Interactions

• Sakayanagi and Katsuragi: Their disagreement pits Sakayanagi’s emphasis on individual worth against Katsuragi’s practical, collaborative mindset.
• Sakayanagi and Rinyu: Their interaction shifts from amusement to genuine curiosity. She teases him, observes his unusual behavior, invites him to the auditorium, and accepts his coffee.
• Rinyu and the class: His unexpected sleep and matter-of-fact self-introduction make him the object of collective laughter, but he refuses to be unsettled by their reaction.
• Morishita and Rinyu: Morishita indirectly initiates the humorous scene by waking him with an eraser pellet.

• Rinyu observes three notable students:
  • Ryuuen Kakeru of Class C, whose arrogance and confidence are immediately apparent.

  • Ayanokoji Kiyotaka of Class D, whose restrained movements and constant observation make him stand out to Rinyu despite attracting little attention from others.
• Arisu notices Rinyu’s interest in Ayanokoji and recognizes that he is perceptive and unusual himself. Their playful exchange becomes more familiar when Rinyu calls her “Alice,” surprising her.
• After the ceremony, Hashimoto Masayoshi invites Rinyu to Keyaki Mall. Rinyu buys necessities for his dormitory, including an expensive coffee machine, spending roughly two-fifths of his points. Hashimoto helps him use a shopping cart after seeing him struggle to carry everything by hand.
• Later, Rinyu approaches Ichinose with an offer to sell information about the school, personal points, and future developments for 500,000 points. Ichinose consults her classmates, and Class B agrees to buy it. Rinyu delays payment until the information proves accurate, trusting Ichinose’s honest reputation.
• Back in his room, Rinyu disables a tiny red tracking or recording device hidden near his collar, implying that he has been monitoring or concealing information from others.
• The following morning, Rinyu discovers that his new body possesses extraordinary stamina, endurance, and explosive power. His morning run leaves him virtually exhausted, suggesting that his physical abilities are close to the human limit.
• He encounters Arisu near the elevator after his run. She catches him staring at her legs and teasingly asks whether he likes what he sees.

Character Developments

• Rinyu avoids giving her a direct answer and reminds her that they must go to class. The two walk together, attracting attention from other students because of their closeness and unusual atmosphere.
• At lunchtime, Arisu brings Kamuro Masumi and Hashimoto Masayoshi to join them. This suggests Kamuro has begun cooperating with or aligning herself with Arisu.
• The group eats together. Arisu feeds Rinyu some pasta, and Rinyu reciprocates by offering her a bite of Mont Blanc cake, knowing it is one of her favorite desserts. Their exchange has a noticeably intimate, almost romantic undertone.
• On May 1, the school reveals the class-point results for the month:
  • Class A: 940 points
  • Class B: 880 points
  • Class C: 670 points
  • Class D: 70 points
• The students learn that class points determine their monthly personal allowances at a ratio of 1:100. They are also told that only Class A graduates are guaranteed access to higher education and employment, while 20 million points can provide an alternative route to Class A or prevent expulsion.
• The revelation shocks most students, especially those in Class D. Arisu immediately thinks of Ayanokoji when Class D is mentioned, then turns her attention to Rinyu, whose calm reaction makes him even more mysterious to her.

Character Developments

• Hoshinomiya Rinyu: Remains composed, perceptive, and difficult to read. He demonstrates domestic competence through coffee preparation and shows subtle consideration toward Arisu. His lack of surprise at the school’s harsh rules suggests he already understands more than he reveals.

• Power and attraction: Arisu’s admiration for strength begins transforming into romantic interest as she encounters someone who is both powerful and mysterious.
• Hidden rules and strategic observation: The chapter emphasizes the importance of reading patterns in the school’s point system. Arisu’s investigation and Rinyu’s guarded responses suggest that the visible rules are only part of the larger game.
• Social hierarchy and institutional cruelty: The school formally reveals its class-based structure, in which academic and professional futures depend on class rankings. The system rewards Class A while severely punishing Class D.

• Mashima warns the class that the upcoming midterm is far more serious: anyone who fails even one subject will be expelled, regardless of their performance in other subjects.

• The study sessions begin across the library, café, and dormitories. The library initially functions as an organized tutoring space.

• Hoshimiya suggests that Kushida, Ayanokoji, and Horikita approach Sakura directly to test whether she knows something. He leaves the matter in their hands.

Character Developments

Chapter Summary: “Turning Point”

1. Key Plot Points and Events

• Kushida and Ayanokoji fail to persuade Sakura Airi to testify on Sudo’s behalf. Sakura’s fear of public attention remains too strong to overcome through ordinary reasoning.
• With the hearing less than a day away, Class D faces a serious crisis: without a witness, Sudo will likely be judged guilty of one-sided violence, expelled, and cause Class D to lose a large number of class points.
• Sudo, Ike, and Yamauchi wait anxiously in Ayanokoji’s room. Although Sudo tries to appear carefree, his fear and frustration are obvious.
• Kushida leaves to make another attempt at persuading Sakura, while Horikita Suzune visits Ayanokoji. Ayanokoji explains that he will no longer try to convince Sakura; instead, he will present her with the situation and allow her to make her own decision.
• The hearing begins the next day. Class C’s students repeat their account of Sudo’s assault, while Sudo is unable to provide evidence disproving them.
• Horikita challenges weaknesses in Class C’s testimony, but her arguments are ineffective without physical evidence or an eyewitness.
