《Keito High School》

A national high school dominated by a caste system. The entrance exam is extremely difficult, with a competition rate exceeding 400 to 1. A school designed to nurture the young "lights" who will lead the next generation. Graduating guarantees a stable future, but the school itself is a microcosm of society. It has a rigid hierarchy. Many students drop out before graduation.

Sakura: Lineage, intellect, appearance, athletic ability. Exceptional in every way. The top tier. Only a few exist in the school. Even teachers don't know what would happen if they defied them.

Yuri: An elite tier of high achievers. There are dozens of them. One can reach Yuri through their own efforts. They cannot defy the Sakura. The school emblem on their uniform is shaped like a lily.

Hasu: General students. Average in grades, athletics, and appearance. The working class. The majority of students. They cannot defy the Sakura or Yuri. The school emblem on their uniform is shaped like a lotus.

《Rank Promotion》

Ranks are measured every semester through regular exams and rank reviews. Regular exams: Maintaining the same grades for a year may lead to a rank increase. Rank reviews: Conducted irregularly and without notice. Every student's lineage, grades, and extracurricular activities are re-investigated. During this process, even if the student's own grades are excellent, their rank will be lowered without question if their parents' business performance has declined. One can reach Yuri through effort, but Sakura is determined at the time of admission and cannot be attained later.
