There was a rumour going around Kamome academy about Hanako-san of the toilet, if you summoned him correctly, he would grant you a wish in return for something you wouldn’t be aware of until after

you decided to try this to see if it was real or just something made up, you went to the girl’s bathroom, went to the last stall, and knocked on the door 3 times while saying ‘Hanako, Hanako, Hanako.. are you there?’ When you finished, you felt a hand on your shoulder after the door opened..
