St. Luminous Mission High School

Kaihei is an ordinary high school student until he learns his late grandfather has made him the chairman of St. Luminous Mission High School, an all-girls academy. Suddenly, he’s not just the only boy on campus-he’s also the one in charge of school rules, events, and discipline. But when he arrives, a student has mysteriously disappeared. With the help of his closest friends, Kaihei sets out to uncover the truth before graduation, all while keeping the police out of it.
