Background / History
Advanced Nurturing High School divides each year into Classes A through D. Although the school publicly advertises perfect employment and advancement outcomes, the benefits are reserved for Class A; Classes B, C, and D are excluded from that treatment. The hidden-rule briefing identifies Class D as the class of students judged least excellent by the school’s overall evaluation system. 1 10
Class D initially failed to recognize that classroom behavior affected Class Points. Its students lost points through tardiness, absences, phone use, slacking, and incomplete work before learning the system’s rules. 10 12
Qiuyue Qi anonymously sold the class information on the hidden rules for 800,000 Private Points. Hirata Yosuke organized the discussion, while Horikita Suzune and the other students ensured the purchase went through despite objections from Ike Kanji, Yamauchi Haruki, and Sudou Ken. 9 10
Organization
| Figure | Role within Class D |
|---|---|
| Chabashira Sae | Homeroom teacher. She oversees Class D for all three school years and repeatedly pressures the class to confront its shortcomings. 2 12 |
| Hirata Yosuke | Initial public organizer. He proposed class introductions, rallied the class after the hidden-rule revelation, and formed a study group for students threatened with expulsion. 2 10 12 |
| Horikita Suzune | A prominent decision-maker who helped secure the hidden-rule information, sought methods to improve Class Points, and initially accepted the island-exam leader role. 10 21 41 |
| Ayanokoji Kiyotaka | A concealed strategist whose actions influenced Class D’s island-exam plan, including the leadership change following Horikita’s withdrawal. 63 69 70 73 |
| Qiuyue Qi | A Class D student and the anonymous information broker known as “X.” His schemes benefited the class at times, though he openly prioritized his own objective of collecting Private Points. 9 67 75 |
| Yukimura Teruhiko | The final leader recorded for Class D during the Uninhabited Island Special Exam. 66 73 |
Major Arcs
Hidden Rules and First-Month Collapse
After purchasing Qiuyue’s information, Class D learned that improper classroom conduct directly reduced Class Points. Hirata urged the class to change its behavior, but the warning came too late to prevent a first-month total of only 310 points. 10 12
The class then faced an academic crisis when Chabashira announced that failing a midterm or final examination resulted in expulsion. Nine students had failed the preceding quiz, prompting Hirata to establish a voluntary study group. 12
Sudou Incident
Sudou’s fight with a Class C student delayed Class D’s point distribution and threatened further deductions. Much of the class doubted Sudou’s claim that he had been provoked, while Hirata insisted that the class should help him find a witness. 22
Uninhabited Island Special Exam
Class D selected Horikita as its initial leader after no student volunteered for the dangerous position. Ayanokoji had suggested Qiuyue as a candidate, but Yamauchi objected, and Hirata ultimately persuaded Horikita to accept. 41
During the exam, Class D cooperated with Class B while trying to identify rival leaders. Qiuyue independently gathered intelligence and manipulated several other classes, while Ayanokoji developed Class D’s concealed countermeasures. 43 64 68
Horikita withdrew because of illness, enabling a leadership change that concealed the final leader from most of Class D. Yukimura later stepped forward as the recorded leader, while Ayanokoji’s answer slip confirmed Yukimura’s identity. 63 65 66 73
Class D finished second with 247 points. Its success relied on correctly identifying the leaders of Classes A and C while avoiding a successful guess against its own final leader. 65
Relationships
- Chabashira Sae — Homeroom teacher. She wants Class D to reach Class A, partly because her own former Class D reached Class B but failed to advance further. 75
- Class B — Partnered with Class D before the Uninhabited Island Special Exam; students from both classes later cooperated to identify Class A’s leader. 27 64
- Class A — Primary higher-ranked rival. Class D’s correct identification of Class A’s island-exam leader contributed to Class D’s second-place finish. 65
- Class C — Rival class involved in Sudou’s disciplinary case and multiple island-exam conflicts, including Ibuki Mio’s presence in Class D’s camp. 22 43
- Qiuyue Qi — A class member whose sale of hidden rules protected Class D from further first-month losses, but whose secret dealings and self-interest made him difficult for classmates to understand. 9 12 67
