Class A

Biodata

Class System and Privileges

• Placement: The school initially sorts students by assessed ability, with Class A designated the highest and Class D the lowest 31.
• Changing ranks: Class designations depend on class points. A lower-ranked class that overtakes a higher-ranked class replaces it; entering Class A does not guarantee remaining there 48.
• Graduation benefits: The school’s promised near-100% higher-education advancement and employment prospects apply only to students who graduate from Class A 48.
• Monthly allowance: Class points determine the private points students receive on the first of each month. Class A’s 980 class points produce an allowance of 98,000 private points per student in May 48.
• Individual transfers: Students can purchase a class transfer for 20 million private points 48.

History

Enrollment and Leadership Contest

Class 1-A begins with Arisu Sakayanagi and Kohei Katsuragi competing for leadership. Katsuragi presents his previous school performance as evidence of his suitability, while Sakayanagi argues that their new school operates differently. Satoshi Satonaka interrupts the confrontation and proposes postponing the decision until the students know one another better 2.

Mashima distributes student IDs holding 100,000 private points and reiterates the school’s compulsory dormitory residence and restrictions on outside contact. The apparently generous allowance becomes an early source of suspicion for Toru Hasegawa 2.

Discovery of the Hidden Assessment

During the first morning study session, Katsuragi questions the school’s unusual arrangements and urges his classmates to limit their spending. Sakayanagi goes further, replaying Mashima’s recorded statement that anything within the school can be purchased with points. Her questions prompt him to acknowledge an ongoing school trial and quote a price of one million points for its rules 9.

Rather than pay, Sakayanagi explains her deductions: the initial allowance does not guarantee identical future payments, and the undisclosed assessment must concern ordinary student conduct. Her explanation wins the class’s support and decisively establishes her leadership 9 10.

Students immediately abandon plans to nap during morning study and begin previewing their textbooks. Sakayanagi then gathers information about her classmates, regarding them as potential tools for confronting Kiyotaka Ayanokoji rather than as friends. Hasegawa later publicly introduces her as Class A’s leader at the club orientation 10 14.

Information Leak and Internal Division

Sakayanagi directs Hasegawa to investigate other classes, particularly Class D because of Ayanokoji. Hasegawa negotiates a one-week commitment, with Masumi Kamuro intended to handle subsequent work 11 12.

Hasegawa later discloses the hidden assessment to Class D and voluntarily informs Masayoshi Hashimoto of his actions. Hashimoto recognizes that helping a rival could create a future threat, but chooses to trust him 34.

Sakayanagi publicly labels Hasegawa a traitor. Hashimoto intervenes, emphasizing that Hasegawa disclosed the leak himself and urging classmates to judge rationally. His defense reduces, but does not eliminate, hostility toward Hasegawa. Mashima privately observes that the class is excellent but contains too many competing agendas 35.

Shift Toward Active Improvement

Hasegawa subsequently proposes proactive study and physical exercise. Sakayanagi acknowledges her own oversight, apologizes, and promises to share her daily notes while encouraging other academically strong students to contribute. The abrupt transition from accusations to cooperation leaves many classmates bewildered 37.

During the end-of-month quiz, Hasegawa asks whether a test excluded from report cards can still affect other evaluations. Mashima confirms that it can, making the otherwise quiet classroom visibly tense 45.

Members and Staff

• Arisu Sakayanagi — Leader whose early deduction of the assessment rules secures the class’s cooperation. Her personal objective is to use its strength to challenge Ayanokoji 9 10.
• Toru Hasegawa — Student Council member who challenges Sakayanagi’s authority, assists Class D, and promotes study and exercise within his own class 23 35 37.
• Kohei Katsuragi — Initial leadership contender; identifies suspicious school arrangements and advocates conserving private points 2 9.
• Masayoshi Hashimoto — Strongly committed to Class A winning its grade. Although initially aligned with Sakayanagi, he develops an independent alliance with Hasegawa 19 20 35.
• Masumi Kamuro — Hasegawa’s neighboring classmate, assigned tasks by Sakayanagi. She later seeks mathematics tutoring from Hasegawa 2 21 37 38.
• Satoshi Satonaka — Mediates the opening confrontation between Sakayanagi and Katsuragi 2.
• Tomoya Mashima — Homeroom teacher who supervises Monday morning study sessions and explains the class-point system when the first assessment ends 9 48.

Assessment Results

First Monthly Assessment

• May allowance: Each Class A student receives 98,000 private points, only 2,000 fewer than the initial distribution 48.
• Teacher’s evaluation: Mashima calls them the most outstanding Class A group he has taught 48.
• Academic results: No students fail the latest quiz; its passing threshold is 36 points, calculated from half the class average with rounding 48.
• Next assessment: Midterm examinations are three weeks away when Mashima announces the results 48.

Relations with Other Classes

• Class D — Rival and intelligence target. Sakayanagi’s interest in Ayanokoji makes it a priority for investigation. Hasegawa, however, suspects its unusual students could eventually pose the greatest threat to Class A 11 21.
• Kikyo Kushida — Social bridge. She befriends Hasegawa and Hashimoto hoping to connect with the rest of Class A. Hashimoto sees the same relationship as an opportunity to gather information 19.
• Cross-class friendships — Competing loyalties. Members of Classes A and D socialize together despite their institutional rivalry. Hasegawa explicitly warns that friendship will not remove the competition between them 46 47.
