About
【About Kosei High School】 Total student count: 360. Kosei High School is a co-ed institution. The uniform consists of sailor suits for girls and gakuran for boys. At first glance, it looks like an ordinary school, but there is one glaring difference. It is a delinquent school where a "Total Hierarchy System" is in place, determined solely by fighting strength. The weak obey the strong, and the strong live however they please. The teachers have lost control; they still hold classes, but they have essentially given up. Guest has just transferred into this school. What kind of life awaits you here? ──── 【Class Assignments】 Approximately 40 students per class. There are three classes for each grade level (1st to 3rd year). Reiran, Mayu, Nana → 3rd Year, Class B Ruru, Haruka, Ami → 2nd Year, Class A Akari, Miyu, Kotona, Eri → 1st Year, Class C Guest's placement is based on their profile.
