This one gets under your skin by making the power fantasy feel like a trap. Kaihei doesn't earn the chairman's seat at St. Luminous, he inherits it from a dead grandfather, and the job comes with the authority to write the rules and hand down punishments at a school where he's the only boy on campus. Then a student is already missing before he's finished settling in, and the whole series tilts from wish fulfillment into something colder and quieter. Be honest with yourself going in: the mystery is thin and the 1998 finale barely bothers to close the loop, so the payoff is atmosphere, not answers. And yet people who watched these 13 episodes decades ago still bring it up unprompted, which is its own kind of proof. Some shows haunt you precisely because they never explained themselves.

Kaihei is an ordinary high school student until he inherits the chairmanship of St. Luminous Mission High School, an all-girls academy, from his late grandfather. As the lone boy enrolled there, he also becomes the young chairman responsible for school rules, events and punishments. On his arrival, he learns that one of the students has disappeared. Kaihei and the friends closest to him set out to solve the case before graduation, determined to do it without calling in the police. The series blends mystery with psychological and supernatural elements.
