Class D

Biodata

Class Standing

• Only Class A is stated to receive the school's advertised employment and higher-education guarantees; class rankings change when a lower class exceeds a higher class in points. 9
• Class points and private points are separate systems. Even when Class D's total was zero, individual points were still distributed under the stated rules. 29

History

Class D begins the school year with students who largely mistake their 100,000 starting private points for unrestricted monthly wealth. Its members rapidly become noisy in class, skip expected activities, spend freely, and fail to recognize that their conduct is being assessed. 2 3

At the first monthly settlement, Class D reaches zero points. Chabashira Sae explains that the class assignments reflect ability, while the students learn that the point gap determines class standing and their future prospects. 12 13

The loss of income exposes major internal weaknesses. Students struggle to afford necessities, blame one another, and fear expulsion; Hirata Yosuke's calls for mutual supervision meet resistance, particularly from Sudo Ken. 14

As midterms approach, Horikita Suzune and Kushida Kikyo organize tutoring for Sudo, Ike Kanji, and Yamauchi Haruki. Their academic foundation proves so weak that Horikita restarts from first-year middle-school material. 23 24 Sudo ultimately fails and is expelled, costing the class another 100 points. 29

The class remains at zero while students from higher-ranked classes openly mock its status. Horikita begins viewing her classmates' shared resentment as a potential source of unity, while Hoshino Kanade concludes that Class D needs enough strength to resist outside pressure despite his lack of interest in leading it to Class A. 31 32

After passing its finals, Class D is offered a private-island trip. The apparent reward proves to be a week-long survival examination requiring communal living, resource management, and cooperation. 42 48 50

Internal Factions

• Kushida Kikyo's social circle — A broad social group centered on Kushida; it includes students seeking social connections, Sakura Airi, neutral students, and seemingly the Problem Trio. 11
• Hirata Yosuke's “Harmony Camp” — A group led by Hirata that includes the Karuizawa group and moderate students such as Yukimura Teruhiko. 11
• Karuizawa Kei's girls' group — Includes Matsushita Chiaki, Shinohara Satsuki, and Sato Maya. 11
• Problem Trio — Sudo Ken, Ike Kanji, and Yamauchi Haruki; their poor behavior and academic weakness contribute heavily to the class's crisis. 11 22 27
• Loners — Koenji Rokusuke maintains limited social contact, while Horikita deliberately isolates herself from the class. 11

Key Members and Staff

• Chabashira Sae — Homeroom teacher for the students’ full three-year term; she is frustrated by Class D's failure to understand the system and seeks a way to make its capable students work together. 2 18
• Horikita Suzune — A high-performing but initially isolated student who takes responsibility for tutoring struggling classmates and pursuing Class A. 23 24 31
• Hirata Yosuke — A socially skilled student who organizes introductions, study sessions, and attempts at class-wide cooperation. 3 22
• Kushida Kikyo — A central social figure whose influence helps bring reluctant students into Horikita's study session. 11 24
• Hoshino Kanade — An academically exceptional yet detached student who initially intends to exploit information for private points rather than assist Class D. He later begins making preparations to protect the class from external threats. 2 32
• Ayanokoji Kiyona — Hoshino's closest classmate and partner; she and Hoshino reject Horikita's proposal to work toward Class A, preferring independence. 2 20
• Sudo Ken — A member of the Problem Trio expelled after failing the midterms; his departure leaves an empty seat and intensifies resentment within the class. 29

Major Arcs

First-Month Collapse

• Class D receives its initial private-point allocation and indulges in the school's permissive environment. 2 3
• The class ends its first month at zero class points, becoming the bottom-ranked class. 12 13
• Financial pressure, blame, and disputes over responsibility begin to fracture the class. 14

Midterm and Expulsion

• Hirata proposes a study group, while Horikita and Kushida recruit the academically struggling students. 22 24
• An exam-scope change causes panic, and Hoshino chooses not to share what he knows with the class. 27
• Sudo fails the midterms and is expelled, triggering another 100-point loss for Class D. 29

Zero-Point Stagnation

• The class endures public humiliation from higher-ranked classes while remaining at zero points. 31
• Horikita attempts to transform the class's suppressed anger into motivation, while Hoshino considers strengthening Class D solely enough to resist other classes. 31 32
• Matsushita Chiaki becomes Hoshino's information-gatherer within Class D in exchange for his protection of her façade and support. 38 39

Island Survival Examination

• Class D boards a luxury cruise believing it has earned a vacation after the finals. 42
• The class encounters open contempt from students of another class before reaching the island. 44
• The school reveals that the trip is a one-week survival test with penalties, resource costs, leader selection, and a final guessing game. 48 50
