Kaihei, an ordinary high school student, unexpectedly finds out that his late grandfather has appointed him as the chairman of his all-girls school, St. Luminous Mission High School. Not only is he the only male student on campus, but he also becomes the young chairman in charge of school rules, activities, and discipline. When Kaihei arrives, though, it appears that a student has gone missing. Determined to solve this mystery without calling the local police, Kaihei and his closest friends set out to find the truth before graduation.
