Background / History

Original Class A

At the beginning of the school year, Class A was regarded as the elite class. Katsuragi Kohei organized its students into a disciplined formation, while Sakayanagi Arisu maintained a separate, influential presence within the class. Their coexistence created a dual-leadership structure rather than a unified chain of command. 4 13

Class A began with 1,000 Class Points and lost only 20 during its first month, retaining 980 points—slightly ahead of Class B’s 960. Its strong discipline made it the natural buyer when Class B sold intelligence on the school’s hidden rules for one million personal points. 14 33

The Uninhabited Island Exam exposed major internal weaknesses. Class A struggled to secure bases, became divided over Katsuragi’s leadership, and ultimately finished tied for last with Class C at zero special-exam points. Its failed leader identification and contract-related debt to Class C intensified criticism of Katsuragi. 108 110 122

Class B’s Promotion

During the subsequent voting exam, Class B tied Class A’s average score and received a 75-point increase. Hoshinomiya Chie declared that Class B had become the “true Class A in name and in fact.” Later accounts identify Kitagawa Kai’s former Class B cohort as First-Year Class A. 135 160

Under Kitagawa’s leadership, the promoted Class A built a major points advantage. By November, it held 1,753 Class Points, compared with Class B’s 1,035, Class C’s 170, and Class D’s −100. 232

Class Culture

The promoted Class A is characterized by high cohesion, disciplined preparation, and unusually strong trust in Kitagawa’s judgment. Students routinely look to him during special exams, threats, and strategic decisions. 160 237

• Students follow organized academic sessions led by Ichinose and Kanzaki. 71
• Kitagawa personally developed the class’s physical-training program and taught practical self-defense. 71
• During Sports Festival preparations, the class adopted a standing precaution: activate recording equipment whenever an incident occurs. 160
• The class maintains large communal funds, allowing extensive spending on food, sports supplies, and celebrations. 179
• Its students recognize Kitagawa, Shibata, and Kanzaki as its foremost physical competitors. 160

Major Arcs

Hidden-Rules Transaction

Class B identified that everyday classroom discipline could affect Class Points, then sold that intelligence to the original Class A for one million personal points under a confidentiality contract. Katsuragi approved the deal, with Mashima Tomoya serving as witness. 12 14

Uninhabited Island Exam

The original Class A was repeatedly outpaced in base occupation by Kitagawa’s Class B. Katsuragi’s faction managed only limited progress, while Sakayanagi’s faction used the setbacks to challenge his authority. 107 108

Class A finished the exam tied for last at zero points. Its students blamed Katsuragi after learning that all three rival classes had correctly identified Class A’s leader. 122

Promotion to Class A

Class B tied Class A in the voting exam and was awarded a 75-point increase. The result elevated Kitagawa’s cohort into the Class A position. 135

Sports Festival

As First-Year Class A, Kitagawa’s class dominated the preliminary events. Kitagawa won every event he entered, while the rest of the class benefited from its extensive prior training. 182

The class partnered with Class D on the Red Team and applied a participant-placement strategy based on avoiding matchups between its strongest competitors. 161

In the Pole-Toppling Competition, Kitagawa led an elite six-person attack group—Hirata Yosuke, Ayanokoji Kiyotaka, Koenji Rokusuke, Kanzaki, and Shibata—which rapidly toppled the White Team’s pole. 183 184

Class A also won the Four-Way Tug-of-War, with Kitagawa deliberately moderating his strength so his classmates could contribute rather than deciding the contest alone. 194

The class finished the Sports Festival with 2,410 points, recorded as the best first-year score in the event’s history. 200

Paper Shuffle Preparation

When the next written-test Special Exam was announced, Class A’s students immediately expected Kitagawa to formulate a response, reflecting the class’s habitual reliance on his leadership. 237

Kitagawa later organized joint study sessions with Class D, assigning class roles to Horikita Suzune, Kushida Kikyo, Hirata Yosuke, and academically capable students to prevent struggling students from being expelled. 269

Interclass Relationships

• Class B — The original Class A purchased Class B’s hidden-rule intelligence for one million personal points; Class B later rose to become the new Class A. 14 135
• Class C — The original Class A entered an island-exam contract with Ryuen Kakeru’s class and was left indebted after its zero-point result. 110 122
• Class D — The promoted Class A cooperated with Class D during the Sports Festival as part of the Red Team, then supported Class D through joint study sessions. 161 269
• Student Council — Kitagawa used the council to expand communication between first-year classes, recruiting representatives from each class. 225
