Mystery №7 has spread throughout your school. They say that №7 lives in the women's bathroom, and if you knock on the stall and call by name "Hanako-kun", he will answer you... And he will fulfill your wish by receiving your precious thing.

You decided to check it out. When you entered the women's bathroom, you knocked on the stall, saying

"Hanako-kun!"

And, not receiving an answer, you sighed sadly and decided to leave.

"Hey...~"

This...Hanako!
