Class Standing
| Period | Standing / Points | Notes |
|---|---|---|
| Initial evaluation period | All first-year classes initially used the same scoring standard. | The following month's standards would differ according to each class's performance during the first month. 13 |
| After the first month's assessment | Lowest class; 0 class points | Class A had nearly 1,000 points while Class D had none. The school's administration identified Class D as its lowest class and labeled its students “defective products.” 47 50 |
Background / History
Class D is the first-year class assigned to students whom the school considers problematic despite their individual talents. Its dormitory placements appear deliberate: Kageya Shinjitsu finds that the rooms around his own are occupied by Class D students. 5 The school's assessment does not rely solely on academics or physical ability; it also judges conduct, social contribution, and other personal factors. 5 48
From the beginning, the class is marked by poor discipline and fractured social dynamics. Its self-introductions are disrupted by Sudo Ken's hostile outburst, while students quickly form cliques rather than a unified group. 4 5 During lessons, several students use phones or handheld consoles, talk, and sleep instead of studying, behavior Kageya recognizes as costing the class points. 10
Kageya uncovers the school’s class-evaluation system before most of his classmates. Rather than share his findings, he decides that Class D is too unreliable to support and sells information to Classes C, B, and A. His agreements are intended to widen the point gap and ensure Class D remains at the bottom while he accumulates private points for an individual transfer to Class A. 13 14 15 16
The plan succeeds. Class D’s exam information is sold to other classes, its collective score falls to zero, and the students are forced to confront their designation as the school’s lowest class. 47 50 The revelation sparks blame, resentment, and arguments over whether the school or the students themselves are responsible. 47 50
Class Culture and Internal Dynamics
- Class D contains students with significant individual ability but serious issues with teamwork, discipline, conduct, or social behavior. 5 9 48
- The class lacks a stable consensus on collective responsibility; students repeatedly blame one another when their points reach zero. 47 50
- Hirata Yosuke and Kushida Kikyo attempt to preserve harmony and morale, but their efforts have limited effect amid the class’s infighting. 45 50
- Several members, including Ike Kanji, Yamauchi Haruki, and Sudo Ken, become focal points of poor conduct and conflict. 29 47
- Kageya and Koenji Rokusuke openly reject the expectation that they should sacrifice their own interests for the class. 45 47

Story Role / Major Arcs
Initial Placement
Class D is introduced as a disorganized group whose members are initially unaware of the school’s meritocratic class system. Kageya quickly suspects that the class has been placed at the bottom for reasons beyond intelligence or athletic ability. 5 6
Information Betrayal
Kageya investigates the school independently, learns how points and class rankings function, and trades that knowledge to the other first-year classes rather than assisting Class D. 7 13 16
Point Collapse
The class’s poor conduct and Kageya’s information deals leave it at zero points. The students discover both their low standing and the school’s “defective products” label, triggering widespread frustration and mutual blame. 47 50
Kageya's Departure Plan
Kageya’s accumulation of private points makes an individual transfer to Class A possible, further alienating him from Class D and demonstrating that the school’s system allows personal advancement without class cooperation. 47 48
