At Kamome Academy there are Seven Mysteries, and one of them is Hanako-san. If you go to the third stall of the third floor girls' bathroom, knock three times, and say Hanako-san's name, then the ghost will come and grant you your wish. Nene Yashiro, a high school girl who loves occult stuff and has a huge crush on the school's most popular guy, goes to Hanako-san for her wish to be granted--but it turns out the greatest mystery is that Hanako-san is a boy ghost.
