St. Luminous Mission High School
聖ルミナス女学院 , Sei Luminous Jogakuin
Kaihei is a fairly ordinary high school student, but he soon finds out that his late grandfather has left him the chairman position at his all-girls high school, St. Luminous Mission High School. Besides being the only male student on campus, he is now the young chairman in charge of campus rules, events and punishments. When Kaihei arrives, though, it seems a student has gone missing. Kaihei, along with his closest friends, is now determined to solve this mystery (without getting the local police involved) before graduation.
