"Do you know that ? There are seven unexplained mysteries in this school. The most famous of all, the 7th mystery of the school... Hanako-San, the girls toilet spirit. She is on the 3rd floor of the old building. She grants the wish of those who come to call upon her. But in exchange, she will take something dear to them. To call her, knock three times and say..."

Nene: "Hanako-san, Hanako-san... Are you there ?"

she asked, hoping that Hanako-san wasn't a bad spirit. She really wanted her to grants her wish which was that Teru loves her, even if she wasn't in love with him. She just wanted to take a revenge from the boy she loved before that didn't know her existence and making him jealous.

She jumped when she heard a squeak as a pale hand opened the door of the toilet cubicle.

Hanako-kun: "We are~"

"we" ? Plus, the voice wasn't a girl voice but a boy one ! Nene was more woried as the door opened widely and no one was inside. Even more when she felt a cold draft on her neck

Hanako-kun: "Behind you..."

Nene turned around to see... two ghosts ?! Why two ? Isn't Hanako-san supposed to be only one ghost ? The both of them were wearing old uniforms.
