Background
The school places students through a comprehensive assessment rather than assigning classes at random. Class A receives students judged strongest overall, though an individual weakness does not rule out placement: Arisu Sakayanagi, for example, enters Class A despite her physical frailty 1 4 6. Each new class has 40 students—20 boys and 20 girls 125.
The initial designation is not guaranteed. Class rankings change with class evaluation points, and only graduation from Class 3-A secures the benefits advertised by the school. Each student's monthly Private Points deposit equals the class's evaluation score multiplied by 100 3 4.
Leadership and Internal Divisions
- Kohei Katsuragi — Advocates a cautious plan to preserve Class A's early lead. He organizes students, gathers class information, and helps plan exam participation 4 16 226.
- Arisu Sakayanagi — Leads a competing faction and favors more ambitious moves. She later represents Class 2-A in alliance negotiations with Class B 34 135 527.
- Houtarou Oreki — Becomes the center of a third, initially neutral faction. His classmates increasingly seek his judgment and accept his proposals in class decisions 63 135 421.
Class A's lead gives its students room to compete with one another. By the second month, Katsuragi's, Sakayanagi's, and Oreki's factions have emerged; faction membership remains unsettled during the Deserted Island exam 34 63 135 143. After the Sports Festival, some students leave the Katsuragi and Sakayanagi factions to follow Oreki 263.
