Background
Chairman Narimori Sakayanagi personally placed Amasawa Yuto in Class A after rejecting an evaluation that described him as exceptionally capable but severely deficient in understanding emotions. Sakayanagi concluded that Yuto would turn whichever class he joined into Class A regardless, making direct placement preferable. 6
The class began the year with a strong academic environment and comparatively cooperative classroom conduct. Its students formed two main political blocs: Kohei Katsuragi’s larger faction and Arisu Sakayanagi’s smaller inner circle, while several students remained neutral or independent. 22
Leadership and Organization
| Figure / Group | Position in Class A | Notes |
|---|---|---|
| Amasawa Yuto | Class leader | Took a public leadership role after Katsuragi’s withdrawal, declaring that the other classes would compete for second place. He is also the first-year Student Council Vice President. 47 70 |
| Arisu Sakayanagi | Former faction leader; Amasawa’s principal partner | Defeated Katsuragi in the leadership struggle and helped unify the class behind its new leadership. 69 70 |
| Kohei Katsuragi | Former leadership contender | Withdrew after acknowledging that he could not compete with both Sakayanagi and Amasawa. He remained a trusted asset, managing Class A’s island-exam purchases. 69 72 |
| Masumi Kamuro | Sakayanagi faction member; island-exam leader | Served as Class A’s actual leader during the Uninhabited Island Survival Special Exam. 61 88 |
| Kito Hayato | Physical-force specialist | Part of Sakayanagi’s core group and one of Amasawa’s key field partners during the island exam. 61 72 |
| Hashimoto Masayoshi | Intelligence specialist | Managed intelligence for Sakayanagi’s faction and supported Amasawa’s strategies. 61 72 |
| Ran Morishita | Independent-to-supportive member | Initially sought an alternative to both Katsuragi and Sakayanagi; later supported Amasawa’s leadership and participated in reconnaissance. 35 70 76 |
| Satoshi Satonaka | Moderate faction member | Assisted Class D’s study session out of personal goodwill rather than factional loyalty. 51 |
Academic Profile
- Class A maintained the highest average academic level among the four first-year classes. 19
- Amasawa achieved a perfect score on the late-April quiz, placing first in Class A and drawing both admiration and resentment from classmates. 30
- The class’s passing score for that quiz was 41; no Class A student failed. 30
- Its academic strength enabled several members—including Sakayanagi, Hashimoto, Kamuro, Morishita, and Satonaka—to tutor Class D ahead of its history examination. 51
Major Arcs
First-Month Competition
Class A’s narrow 20-point lead over Class B intensified internal concerns about leadership. Katsuragi argued that the class needed to preserve its position for all three years, while Sakayanagi and Amasawa pursued their own approaches to the school’s point system. 29 32
Amasawa’s actions also benefited Class B by helping secure a 500,000-point discount, leading Kanzaki Ryuji to suspect that he was trying to expose Class A’s existing leaders as inadequate. 25
Leadership Struggle
Sakayanagi’s faction gained ground through clearer organization: Kamuro handled assistance, Kito provided force, and Hashimoto gathered intelligence. Katsuragi, by contrast, largely relied on himself and Totsuka Yahiko. 61
Katsuragi eventually withdrew from the leadership contest, accepting Sakayanagi’s superiority and the futility of opposing both her and Amasawa. Soon afterward, Amasawa formally committed himself to leading Class A, rallying the class behind a united two-person leadership structure. 69 70
Uninhabited Island Survival Special Exam
Amasawa organized Class A around a cave base, delegated supply management to Katsuragi, and used Kamuro and Kito as trusted field partners. 72
The class’s central deception made Kamuro its real leader while Amasawa purchased a fake leader card bearing his own name. The plan led Ryuen Kakeru to believe that he had exposed Class A’s leader, causing Class C and Class D to submit an incorrect guess. 88
Class A finished first with 412 points. Its score included 150 points for correctly identifying the leaders of Classes B, C, and D, plus 122 points from occupied bases. 87
Dragon Group Examination
Amasawa, Kamuro, and Katsuragi represented Class A in the “Dragon” group, alongside leading students from the other three classes. Amasawa unexpectedly declined to participate in the examination’s contest for its rewards, instead leaving with Shiina Hiyori of Class C. 96
Relationships
- Arisu Sakayanagi — Leadership partner and former faction ally; their shared influence became the foundation of Class A’s unity after Katsuragi withdrew. 69 70
- Kohei Katsuragi — Former internal rival; remained useful to the class after stepping down, particularly in resource planning during the island exam. 69 72
- Class B — Amasawa’s assistance with a point discount contributed to Class B’s unusually strong first-month total, creating suspicion about Class A’s intentions. 25 29
- Class C — Principal competitive rival during the island exam; Class A’s false-card strategy caused Ryuen’s class to misidentify its leader. 82 87 88
- Class D — Class A provided academic support before the history exam and later shared Class C’s leader information to offset Class D’s likely penalty during the island exam. 51 87
