Background / History
Advanced Nurturing divides each grade into Classes A through D in descending order of school evaluation. Class A alone receives the advertised employment and higher-education privileges, while Class D is explicitly presented as the grade's lowest-rated and most hopeless group. 3 326
During the first-month Behavioral Norms Exam, Class D purchased information on the hidden evaluation system from Chabashira. The class nevertheless spread the information freely, lacked a central leader, and allowed louder students—especially Yamauchi Haruki—to shape its reactions. 26 27 The class finished the exam with zero points, after which its members turned on Yamauchi and the classroom descended into shoving and fighting until Hirata Yosuke intervened. 35
The zero-point result and threat of academic expulsion temporarily improved discipline. Hirata spent his remaining points to move beside Yamauchi and help him study, while many students began taking lessons seriously. 54 However, the class's internal division persisted: when students confronted Chabashira over her own former Class D's failure in the Unanimous Special Exam, the teacher fainted under the pressure. 56
Class Dynamics
- Weak collective cohesion — Class D repeatedly struggles to act as a unified group, with small cliques, conflicting priorities, and volatile public opinion. 21 27 56
- Crisis-driven discipline — Students become more attentive after losing their allowance and learning that academic failure can lead to expulsion, but this restraint is fragile. 35 54 56
- Dependence on informal leaders — Hirata repeatedly calms disputes and supports struggling classmates, though he cannot compel cooperation from figures such as Koenji Rokusuke or earn every student's trust. 35 54 56
- Susceptibility to manipulation — Asakusa uses the class's financial desperation and fear of the school's evaluation system to push the Zero Point Plan and other disruptive games. 326 329 330
- Hostility toward the higher classes — Class D's later strategy treats Classes A, B, and C as opponents to be dragged down rather than competitors to surpass conventionally. 332 333 335
Major Arcs
Behavioral Norms Exam
Class D learns that misconduct is being quietly tracked and deducted from its class evaluation. Although the class obtains the exam details for 200,000 points, it fails to maintain discipline and ends the month at zero points. 26 35 38
Midterm Crisis
The school announces that failing even one subject can result in expulsion. Yamauchi becomes the class's scapegoat after the zero-point result, while Hirata attempts to preserve order and keep students from abandoning one another. 35 49 54 In the eventual results, Sudo Ken narrowly passes, Yamauchi passes English, and Ike Kanji fails every subject. 76
Borrowing Negotiations
Facing a need for 1.2 million Private Points, the class contacts Asakusa through Kushida. He agrees to provide the money within five minutes, leaving Class D stunned by the speed of the arrangement. 78
VIP Exam
Kushida Kikyo is assigned as Class D's VIP in the Dragon Group, alongside Hirata Yosuke and Horikita Suzune. 219 A three-class alliance later forces Class D to surrender; Class B and Class D agree to pay Class A 3.5 million Private Points to avoid further deductions, while Kushida's VIP identity remains unreported. 231
Question-Set Special Exam
Class D is paired against Class A in a subject-based special exam. Sakura Airi transfers out of Class D, leaving it with an odd number of students and forcing one median student to compete alone with their score counted twice. The class finishes with 692 total points but remains at zero Class Points. 258
Mixed Training Camp
During the eight-day mixed-grade camp, Class D's students are divided into groups with students from other classes and years. Horikita joins Ichinose Honami's group, while Karuizawa Kei and Kushida lead separate Class D girls' groups despite the risk of expulsion. 263 266 Yamauchi's group finishes last; he is expelled and chooses Hirata as the additional person to be expelled from his group. 268
Class Vote
Koenji Rokusuke is forcibly expelled from Class 1-D after placing last in the Class Vote. Asakusa selects Kushida as the class's Protection Point holder during the same period. 276
All-Member Zero-Point Special Exam
Asakusa presents Class D with the Zero Point Plan, demanding 90,000 Private Points from each student and proposing harassment-based games such as Musical Chairs and Whisper Game. The class accepts despite its fear and hesitation. 326 329
Class D subsequently occupies more than half of Class A's classroom seats, triggering a confrontation between the two classes. The opening stage of the All-Member Zero-Point Special Exam is Musical Chairs, with Class D attacking and Class A defending their seats. 332 333 335 The game ultimately ends with all four classes “liberated”; no physical harm occurs, and the event is characterized as a psychological experiment. 337
Relationships
- Chabashira Sae — Homeroom teacher and former Class D student. Her history, including the failure of her own class in the Unanimous Special Exam, becomes a source of anger and distrust among her students. 26 51 56
- Horikita Suzune — A strategically minded Class D student who becomes increasingly frustrated with classmates she considers defective and unreliable. 35 263
- Hirata Yosuke — The class's primary stabilizing presence; he breaks up conflicts, tutors Yamauchi, and repeatedly attempts to preserve unity. 35 54 56
- Yamauchi Haruki — A disruptive classmate whose actions contribute to the class's poor reputation and zero-point result. He is later expelled during the Mixed Training Camp and vindictively targets Hirata. 27 35 268
- Kushida Kikyo — A socially influential member who serves as Class D's Dragon Group VIP, later leads a girls' camp group, and is selected as the class's Protection Point holder. 219 266 276
- Koenji Rokusuke — An exceptionally capable but uncooperative student who refuses Asakusa's games and is ultimately expelled through the Class Vote. 137 330 276
- Asakusa Toru — An outside manipulator and later Class D participant who offers loans, exploits the class's desperation, and directs its zero-point and classroom-occupation strategies. 38 326 329 332
