Toilet-bound Hanako-kun

Kamome Academy's seven school mysteries are real, and Hanako-san — the rumour about a ghost in the third stall of the third-floor girls' bathroom — is the most famous of them. First-year Nene Yashiro summons her with the standard chant, asking for a wish, and finds out two things at once: Hanako-san is real, and Hanako-san is a teenage boy in suspenders. The series follows Nene as Hanako's unofficial assistant, navigating the rest of the school's apparitions, and the slowly-revealed reason a boy is haunting a girls' bathroom in the first place.
