Toilet-Bound Hanako-kun, Vol. 1

Every school has an urban legend about "Hanako-san of the toilet," a spirit said to grant any wish — for a price. Nene Yashiro, a student hoping for romantic luck, summons him and ends up dragged into his world instead: Hanako-kun, a ghost boy bound to the school's supernatural bureaucracy, needs a human ally to help him manage the wandering spirits and apparitions that haunt the building's seven mysteries.
