Class D

Biodata

Background / History

Class D is one of the school’s four first-year classes. Students are assigned to Classes A–D according to the gap between their strengths and flaws; rankings may later change through class points earned in monthly special exams. Private Points can be used as a resource in this competition. 7

From the outset, Class D is characterized as the school’s lowest-ranked and most disorderly class. Aragaki Shun finds it sufficiently unstable that allowing it to fall to zero class points could turn its students into assets for any class willing to buy their cooperation. 19 20

Despite its reputation, Class D contains several students with substantial potential. Koenji Rokusuke is considered one of the strongest students in the year, while Kushida Kikyo and Hirata Yosuke are regarded as capable contributors if their personal issues do not cause them to collapse. Chabashira Sae also identifies Ayanokoji Kiyotaka as a potentially exceptional but enigmatic student. 20 32

Notable Members

• Horikita Suzune — An initially isolated student determined to reject her Class D placement and eventually lead the class upward. 19 43
• Ayanokoji Kiyotaka — A mysterious student later pressured by Chabashira into helping Class D avoid expulsion and rise toward Class A. 102
• Koenji Rokusuke — A highly capable but detached student who initially prefers collecting Private Points independently rather than competing for Class D. 12 20
• Kushida Kikyo — A socially influential student whose ambition and instability make her a recurring candidate to manage the class. 17 136
• Hirata Yosuke — A student who helps maintain order and attempts to protect classmates, including Sudo during the midterm crisis. 19 58
• Karuizawa Kei — Later described as Class D’s leader; she works with Aragaki while attempting to preserve the class’s position. 135
• Wang Meiyu (Xiao Mei) — Transfers from Class D to Class A with Aragaki’s assistance. 111 122
• Sudo Ken — Fails the midterm and faces expulsion despite Hirata and Kushida’s intervention. 58
• Yamauchi Haruki — Transferred out to Class A by Aragaki using a Transfer Ticket. 20 21
• Ike Kanji — Transferred out to Class C by Aragaki using a Transfer Ticket. 20 21

Story Role / Major Arcs

Early-Year Decline and Aragaki’s Intervention

Aragaki audits Class D to investigate its past exams and internal dysfunction. During the visit, he intervenes when Chihiro Shiranami is harassed, observes the class’s divided reactions, and remains wary of Kushida’s attempt to befriend him. 17

He subsequently sells Class D information about the school’s hidden rules, class rankings, Behavioral Standards Exam, and transfer system in exchange for recurring Private Point payments. Most students accept; Koenji refuses. 19 20

To expose the disruptive potential of the Transfer Ticket system, Aragaki transfers Yamauchi to Class A and Ike to Class C. His stated objective is not simply to drain rival class points, but to demonstrate to the school how transfers can distort class competition. 20 21

Midterm Crisis

Class D’s poor performance culminates in Sudo failing the midterm and facing expulsion. Hirata and Kushida plead with Chabashira, but she refuses to intervene, disappointed by the class’s lack of improvement and unity. 58

Class A’s Recruitment and Resource Pressure

Aragaki uses Class D as a source of recruits and resources. He offers students access to Class A in exchange for temporary points, recruits Wang Meiyu, and leaves Class D with a reduced pool of temporary points that members may sell for personal profit. 110 111

Wang’s eventual transfer to Class A intensifies Class D’s internal tensions, particularly Kushida’s jealousy and resentment. 122

Subordination Under Class A

During the Uninhabited Island Exam, Class D joins an arrangement led by Aragaki, exchanging temporary points for supplies. The deal provides compensation but leaves Class D at the greatest disadvantage among the participating classes. 113

Aragaki later seeks to formalize Class A’s control over the lower-ranked classes. He considers Horikita, Kushida, and Hirata as possible Class D managers, then offers Kushida a path to transfer to Class A if she successfully manages Class D. 135 136

Selection Exam

By the Selection Exam, Kushida is recognized as Class D’s leader. Class D is paired against Class C, led by Manabe Shiho, while Aragaki declines to provide further assistance to either lower-ranked class. 261

Class Dynamics

• Class D begins with low discipline, poor cooperation, and a severe risk of losing all class points. 19 43
• Its strongest members are hindered less by raw ability than by detachment, interpersonal conflict, or lack of shared purpose. 20 32
• The class repeatedly becomes subject to Aragaki’s financial leverage, recruitment strategy, and broader effort to control Classes A, C, and D. 110 135 176
• Chabashira views Class D’s promotion as personal redemption and eventually secures Ayanokoji’s agreement to assist the class. 102
