Background / History
Class 1-D began the school year with substantial private-point allowances and considerable freedom. Its students quickly displayed sharply different attitudes: Hirata Yousuke attempted to create a cooperative atmosphere, Kushida Kikyou sought to become a central social figure, while students such as Sudo Ken, Kouenji Rokusuke, Horikita Suzune, and Ayanokouji Kiyotaka openly distanced themselves from the group in different ways. 2
Tatsuya Sakuya deliberately controlled his entrance-exam scores to enter Class 1-D. Although he initially stated that he intended to remain uninvolved unless the class affected his life, he regarded the class's predictable decline as an opportunity to eventually establish authority. 1 18 31
During the first lessons, the class mistook Chabashira Sae's lack of immediate intervention for permissiveness. Students arrived late, slept, played games, used phones, chatted, and left class early, unaware that every infraction was being recorded against the class's point total. 6
Class 1-D briefly gained positive attention when Sakuya won the freshman 50-meter freestyle event with a school-record time of 21.91 seconds. His result made him a recognized swimming ace and increased his influence within the class. 11 14
On May 1, Chabashira revealed that the class had exhausted all 1,000 of its Class Points. The loss of monthly Private Points triggered financial panic, infighting, and an immediate academic crisis because students who fail a subject's required score in the upcoming midterms face expulsion. 31 32
Sakuya obtained the previous year's first-year midterm papers and solutions, then presented them to Class 1-D as a means of avoiding expulsions. He used the papers to support his candidacy for class secretary and won 30 of the class's 40 votes. He subsequently formed a Class Committee to coordinate academic preparation, although Kouenji and Ayanokouji initially declined positions. 36 37 40 41 42
Under the committee's direction, the class began mutual-aid study sessions. An initial session at Palette Café broke down after Horikita's confrontation with Sudo, Ike, and Yamauchi. Sakuya moved the sessions to the library and enlisted Kushida to help reconcile the three boys with the study effort. Horikita took charge of the study schedule, while Hirata, Kushida, Karuizawa, Ayanokouji, and stronger students helped their classmates. 45 47 49 51 54
When Sakuya learned from Ichinose that the midterm exam scope had changed, Class 1-D discovered that Chabashira had received the notice days earlier but had not passed it on. Horikita obtained the revised scope and reorganized the class's preparation. The class later completed the midterms; Sudo required a makeup-exam opportunity, but every student ultimately passed. 59 60 61 70
In June, the class learned it had recovered to 78 Class Points. Its organizers agreed to continue regular study sessions rather than depend on purchased exam papers. Sakuya also secured the committee's approval to appoint Ayanokouji despite his objections. 70 71
By July, Class 1-D faced another threat when three Class 1-C students accused Sudo of assault. Sudo maintained that they attacked first, but he could provide no witness or footage. The Student Council scheduled a formal hearing for the following day, leaving the class little time to find evidence; his expulsion would cost it 300 Class Points. 81 82
Class Character
- Undisciplined at the outset — The class accumulated widespread attendance and classroom-conduct violations during its first month. 6 31
- Internally fragmented — Socially cooperative students such as Hirata and Kushida coexist with isolated, confrontational, or self-interested students, preventing a unified class identity. 2
- Academically uneven — Several students struggle severely with advanced mathematics, while Sakuya and Horikita demonstrate substantially stronger academic ability. 20 21 27
- Capable of individual excellence — Sudo, Kouenji, Ayanokouji, and Sakuya all perform strongly in physical testing, though their abilities do not initially translate into class-wide coordination. 7 8 11
- In crisis after May 1 — The point loss exposes the class's financial dependence, weak trust, and lack of practical leadership. 31 32
- Increasingly organized — The Class Committee, regular study sessions, and Horikita's review materials help the class prepare collectively and avoid midterm expulsions. 41 47 54 61 70
- Still vulnerable to individual misconduct — Sudo's temper and the allegation against him place the class at risk of a major point penalty despite its academic recovery. 81 82

Relationships
- Chabashira Sae — Homeroom teacher. She monitors the class's conduct, reveals its point deductions, and warns that failing the academic standard in any subject results in expulsion.

- Class 1-A — The first-year leading class, holding 990 CP in May and 1,100 CP by July 1. Sakayanagi Arisu's assessment labels Class 1-D the “Gathering Place of Defective Products”; Sakuya later sells Sakayanagi past midterm papers. 19 32 36 80
- Class 1-B — A rival class led informally by Ichinose Honami's trust-based approach; it retains 800 CP in May and holds 891 CP by July 1. Ichinose's information about the revised midterm scope enables Class 1-D to change its study plan. 18 32 59 80
- Class 1-C — A rival class operating under Ryuen Kakeru's intimidation-based leadership; it retains 700 CP in May and holds 788 CP by July 1. Its students provoke Class 1-D during library study, and three later file an assault complaint against Sudo. 18 32 51 52 80 81

Major Arcs
First-Month Misconduct
Class 1-D spends its initial allowance freely and fails to recognize that the school evaluates attendance and behavior. Chabashira records the mounting violations without immediately disciplining the students. 3 6
Swimming Performance Test
Sakuya's school-record 50-meter freestyle victory gives Class 1-D an unexpected public success and establishes him as one of its most influential students. 11 14
Points Collapse and Midterm Crisis
The class learns that its Class Points have fallen to zero, leaving many students without funds for regular meals. Chabashira further reveals that the midterm passing line will be half the class average, placing several students at risk of expulsion. 31 32
Search for a Practical Solution
Hirata advocates unity and peer tutoring, but Sakuya dismisses moral persuasion as insufficient. He begins pursuing concrete resources, including past midterm papers, to address the class's academic danger. 32 34
Sakuya acquires the papers and solutions, presents them to the class, and wins election as class secretary. His committee organizes mutual-aid tutoring. After a difficult first session at Palette Café, the study group moves to the library and continues preparing together. 36 40 41 45 47 49 54
Midterms and Point Recovery
News of a changed exam scope forces Horikita and the other organizers to revise their study materials shortly before the midterms. Every student ultimately passes, including Sudo after a makeup-exam opportunity. The class gains 100 Class Points for the result, loses 22 to rule violations, and reaches 78 CP. Its members agree to continue studying regularly for future exams. 59 60 61 70 71
Sudo Assault Allegation
Three Class 1-C students accuse Sudo of assault. With his account of self-defense unsupported by a witness or camera footage, the Student Council schedules a hearing for the next day. Class 1-D searches for evidence, while Sakura agrees to provide Sakuya with a recording relevant to the incident. Sudo's potential expulsion carries a 300-Class-Point penalty. 81 82
