Background / History

Class D is the designation assigned to the school’s lowest-ranked students. Class letters reflect a class’s level of excellence rather than random placement, while Class Points determine ranking; any class that surpasses the current Class A assumes its position and receives Class A’s preferential treatment. 3 14

The initial first-year Class D collapsed during its first month. Chabashira Sae cited 98 incidents of tardiness or absence and 391 cases of classroom disruption or phone use, resulting in an evaluation of zero. She further explained that improved conduct would not restore points in the following month, leaving the class dependent on free school facilities and food options. 14

Despite its poor collective discipline, the class contained considerable individual talent. Its core problem was an inability to coordinate those strengths into a unified strategy. 86

First-Year Conflicts

Shiraishi Makoto identified Class D as a target early on and coerced Kushida Kikyo into arranging a purchase of archived exam questions from upperclassmen, which he planned to document as evidence. 22 24

During the Sudo Ken assault case, Class D initially lacked physical evidence against Class C. Horikita Suzune challenged inconsistencies in Class C’s account, arguing that the three students had intentionally provoked Sudo and allowed themselves to be injured to frame him. A later voice recording forced the Student Council to reconvene the hearing. 51 52

Uninhabited Island Exam

Class D established its camp beside a river and conserved Exam Points by purchasing only minimal necessities, including four eight-person tents. The class also sheltered Ibuki Mio after her removal from Class C. 59

Its camp became divided after Karuizawa Kei’s underwear went missing. The boys and girls began living separately, while the girls spent points on amenities such as fans and floor mats despite the boys’ preference for austerity. 63 64

Although Class D’s leader was identified and the class lost temporary points from bases, it retained 95 points—second place behind Class A, while Classes B and C scored zero. 68

Recovery and Promotion

Class D publicly relied on Hirata Yosuke, Horikita Suzune, and Kushida Kikyo as its leaders during the Privileged Person Exam. Its fragmented decision-making made it vulnerable to Shiraishi’s attempts to sell Class A’s VIP information and pressure the class into a costly deal. 76 79 82

The class later cooperated with Class A during the Sports Festival by exchanging information on each side’s weaker competitors. This arrangement was deliberately limited: neither class shared its strongest athletes’ placements. 113

After Sotomura Hideo was exposed as an informant and expelled for secretly filming inside the girls’ restroom, Class D fell to 60 Class Points. 115 125 146 It later recovered to 136 points and was promoted to Class C, shedding the designation it had carried since enrollment. 196

Later Class D and the Zero-Point Strategy

A later Class D faced severe internal instability under Ryuen Kakeru’s returning influence. Some students sought his expulsion because of his prior violent leadership, while Ryuen rebuilt support among followers such as Ishizaki Daichi and Ibuki Mio. 206

Ryuen’s Zero-Point Strategy offered the class an alternative to direct advancement: Class D would support other classes in exams in exchange for a negotiated share of Class Point compensation. Deals with Class A offered an 80% return, while cooperation with Classes B or C could demand 90% or more. 202 213

Shiina Hiyori later served as Class D’s command tower in a special exam against Class C. Class C won all seven events and stripped Class D of its remaining points. 216 228

Composition and Characteristics

• The initial Class D included students with major but poorly integrated strengths, including Horikita Suzune, Koenji Rokusuke, and Ayanokoji Kiyotaka. 86
• Sudo Ken, Kushida Kikyo, and Sakura Airi were described as potentially top-tier students in their respective specialties. 86
• The class’s academic ability was highly uneven: it included excellent students as well as some of the school’s lowest-ranked students. 146
• Athletic ability was one of the class’s notable strengths, though it did not compensate for weaknesses in broader class competition. 201
• Class D repeatedly struggled with internal distrust, factionalism, and insufficient leadership cohesion. 73 83 206

Leadership

• Hirata Yosuke — Public leader whose cooperative approach emphasized hearing the class’s opinions; he believed Class D’s defining quality was its potential. 76 79 86
• Horikita Suzune — Public leader with strong ambition to advance the class; capable in analysis but initially lacked prestige and struggled to unite classmates. 76 83
• Kushida Kikyo — Public leader with an extensive social network; secretly acted under pressure from Shiraishi and exploited Class D’s internal divisions. 22 76 82
• Ayanokoji Kiyotaka — The class’s suspected hidden strategist. His interventions were credited with preserving Class D’s island-exam result, and Class C later harassed the class in an attempt to expose him. 73 154
• Ryuen Kakeru — Later sought to restore his control over Class D and establish the Zero-Point Strategy after the class lost faith in ordinary advancement. 206 213
• Shiina Hiyori — Later served as Class D’s command tower during its match against Class C. 216

Relationships

• Chabashira Sae — Homeroom teacher of the initial Class D; bluntly informed the class that it was composed of the school’s lowest-ranked students. 14
• Class A — Alternated between assistance, exploitation, and strategic cooperation. Class A donated more than 200,000 Private Points before the island exam and later allied with Class D for the Sports Festival. 59 113 181
• Shiraishi Makoto — Treated Class D as both a strategic threat and an exploitable target; he attacked its exam preparations, offered costly VIP information, and assisted in exposing its Sports Festival informant. 22 79 115
• Class C — A principal rival. The classes clashed over Sudo’s assault case, Class C later targeted Class D to expose its hidden strategist, and ultimately defeated Class D 7–0 in a special exam. 51 154 228
• Ibuki Mio — A Class C student temporarily taken in by Class D during the Uninhabited Island Exam after conflict with Ryuen’s group. 59
