Background

Class D is the school’s lowest class tier, initially populated by students the institution considers “defective products” because of shortcomings in academics, conduct, social ability, or other areas of evaluation. The designation does not necessarily mean that every student lacks talent: the school’s assessments heavily value social ability and comprehensive performance rather than academic results alone 3 23.

All classes begin with 1,000 Class Points, which are converted into Private Points at a 1:100 rate each month. Tardiness, absences, and misconduct reduce a class’s total, while special exams and events can restore or increase it. If a lower class surpasses the class above it, their rankings automatically switch 11.

The original Class 1-D immediately demonstrated the problems associated with the designation. Its students ignored classroom discipline, accumulated deductions, and fell to zero Class Points in the first monthly tally 12 17. Despite this collapse, Horikita Manabu assessed the class as the weakest overall but also the one most capable of an upset, since it contained students with extreme individual strengths that could become decisive if properly united 32.

Historically, students had been told that no Class D had ever risen to Class A and graduated from it, a reputation that discouraged several members from committing to the class’s advancement 89 143.

Structure and Leadership

Class D initially lacked a single recognized leader.

Figure	Position within Class D	Notes
Hirata Yosuke	Core figure	His leadership and upright conduct helped maintain class cohesion, but his reluctance to impose discipline limited his authority 23 24.
Kushida Kikyou	Core figure	Her social influence allowed information and opinions to spread quickly through the class; she prioritized maintaining harmony and popularity 23 24.
Horikita Suzune	Island-exam leader	Chosen as the class leader during the Uninhabited Island Special Exam after guiding the group to a base and demonstrating preparation and initiative 133 140.
Shimizu Akira	Independent strategist	Repeatedly declined the class representative role despite being viewed as a potential leader. He instead acted through information deals, planning, and selective intervention 23 143.
Kouenji Rokusuke	Unpredictable individualist	His independent actions repeatedly disrupted group plans, including prematurely reporting a VIP during the cruise-ship exam 140 176.

Shimizu initially judged Hirata and Kushida to be influential “core figures” rather than true leaders. In his view, Class D’s inability to enforce discipline or make unpopular decisions was a major reason it remained disorganized 24.

Major Arcs

First-Month Collapse and Recovery

Class D’s first month ended with zero Class Points after widespread rule-breaking and poor discipline 17. Shimizu’s discovery of the school’s hidden systems and the class’s use of rented surveillance information helped it avoid a repeat collapse; by May, its total had risen to 530 points 50 133.

Cooperation Against Class C

When Sudo Ken faced possible expulsion over a fight, Class D worked with Class B to secure testimony from students harassed by Class C. The alliance cleared the path for a counterattack against Class C’s misconduct and demonstrated that Class D could coordinate with another class when its interests aligned 121.

Uninhabited Island Special Exam

During the Uninhabited Island Special Exam, Horikita served as Class D’s official leader while the class established a riverbank base and organized supplies, meals, communications, and daily check-ins 133 140.

On the final day, Shimizu became Class D’s leader and revealed that he had secretly recorded all four classes changing their leaders. The recording gave Class D confirmed information on the leaders of Classes A, B, and C, allowing it to control the final outcome 156 158. Shimizu declined to identify Class B’s leader because of the classes’ cooperation, and Class D ultimately finished first with 255 Exam-Specific Points 159.

Promotion from Class D

The original Class 1-D cohort’s results across the previous special exams raised it out of the lowest tier. By the Sports Festival, it had become Class C with 860 Class Points, while Ryuen Kakeru’s former Class C had fallen into the Class D position 200.

Notable Members

• Shimizu Akira — A physically exceptional student and information broker whose intelligence gathering, surveillance arrangements, and special-exam plans repeatedly benefited the class 133 156.
• Horikita Suzune — A determined strategist focused on leading the class toward Class A; she became the leader for the Uninhabited Island Special Exam 30 140.
• Hirata Yosuke — A well-regarded class unifier whose sense of responsibility made him one of the class’s central figures 23 154.
• Kushida Kikyou — A highly influential social figure who disseminated information, coordinated with other classes, and shaped internal opinion 23 121.
• Ayanokouji Kiyotaka — A capable but initially low-profile student whom several classmates considered a possible leader alongside Shimizu 143.
• Kouenji Rokusuke — A self-directed student whose ability is offset by his refusal to consistently cooperate with class plans 32 176.
• Sudo Ken — An athletic but impulsive student whose fight incident endangered the class before its members organized a defense 97 101.
• Yamauchi Haruki — A disruptive student whose lies and later betrayal of Class D damaged internal trust 17 185.

Relationships

• Chabashira Sae — Homeroom teacher. She viewed Class D as a difficult but potentially promising group and used information deals to test and influence its internal leadership 23 24.
• Class B — Ally during the Sudo Ken incident and the Uninhabited Island Special Exam; Class B’s support and voice recorder were central to Class D’s final island strategy 121 159.
• Class C — Primary early rival. Its harassment of Class B and involvement in Sudo’s case led to escalating hostility with Class D 95 121.
• Class A — Higher-ranked competitor. Sakayanagi Arisu provided Class D with advance information concerning a special exam, though the two classes remained rivals 70.
• Ryuen Kakeru’s Class D — After the original Class 1-D was promoted, Ryuen’s former Class C inherited the Class D designation and became subject to reduced facilities under Nagumo Miyabi’s policy 200 232.

Later Class D Designation

After the original Class 1-D became Class C, the Class D rank was occupied by Ryuen Kakeru’s class 200. Nagumo Miyabi used this new Class D as the first target of his ability-based reforms, reducing its dormitory conditions and classroom equipment to establish a harsher hierarchy between the four class ranks 232.

The policy was evaluated and applied monthly, allowing a class to avoid Class D treatment if it restored its ranking before the next monthly assessment 233. Under Ryuen’s leadership, this later Class D relied heavily on physical contests, intimidation, and aggressive strategies against rival classes 368.
