Classification and Standing
- Initial placement: Toru Hasegawa describes the school’s initial sorting as based on “superficial ability,” with Class A rated highest and Class D lowest. He stresses that all classes nevertheless begin on equal footing 31.
- Behavioral issues: Hasegawa concludes that personal difficulties help explain several students’ placement: Ayanokoji’s emotional detachment, Horikita’s rejection of friendships, Kushida’s desire to befriend everyone, and Sakura’s concealment of her true self. This is his interpretation of their assignments 27.
- Reputation: Second-year students identify Sudo as a Class D student from his aggressive behavior and mock him as a “defective product” 6.
- Potential: Despite its reputation, Hasegawa considers Class D a possible major threat to Class A because of students such as Ayanokoji, Horikita, and Kushida 21.

| B | 650 48 |

History
Opening Week
Class D first appears in the entrance-ceremony lineup, where Hasegawa notices Ayanokoji’s unusual 0/100 progress-bar reading 3. Shortly afterward, Sudo’s confrontation with upperclassmen exposes the contempt attached to the Class D designation 6.
Classroom discipline deteriorates when students discover that teachers do not intervene. Kushida tells Hasegawa that the noise makes it difficult to listen to lessons, with class time becoming little different from free time 19. Hashimoto later independently observes that Class D is in disarray 28.
Class A’s Investigation
Arisu Sakayanagi prioritizes investigating Class D because Ayanokoji belongs to it. Hasegawa negotiates an agreement to gather intelligence for one week 11 12. He questions Sudo and his friends about their interests and joins the Class D boys’ group chat; both Ayanokoji and Horikita subsequently challenge him about his probing 14 15.
Kushida also establishes contact with Hasegawa and Hashimoto, hoping to use those friendships to meet more Class A students. Hashimoto views her openness as an opportunity to obtain information about Class D 19.
Discovery of the Monthly Assessment
Hasegawa warns Horikita that the school evaluates everyday behavior and that Class D’s conduct threatens its future. His intervention pushes her to seek Ayanokoji’s cooperation rather than act entirely alone 31 33.
At the start of the second week, Kushida announces that the current month is an assessment linked to the next month’s points. Ayanokoji explains the information’s Class A source, while Hirata urges everyone to improve over the remaining three weeks instead of arguing about past mistakes. Kushida supports him, and the class restrains its usual restlessness—even Sudo, who fears losing his private points 35.
The change surprises Chabashira, particularly Hasegawa’s willingness to inform Horikita and Ayanokoji’s decision to act. It does not immediately resolve internal resentment: Ike and Yamauchi continue experiencing subtle isolation from classmates 35 36.
First Assessment Result
In early May, Class D finishes last with 400 class points. Class A students speculate that it might have reached zero without advance warning, but this remains their conjecture rather than a confirmed outcome 48.
Notable Quote
“We need to perform well over the remaining three weeks and strive to recover the school's evaluation of us.”
