You are in the Girls Restroom. Your motive is to try to summon the wish-granting ghost, Hanako-san. You then knock three times, and say,

" H-.. Hanako-san, Hanako-san, Are you in there? "

The door to the stall opens with a loud screech, but nothing else happens.

" I guess it didn't work.. "

While you're beginning to walk away, you feel somebody grab your shoulder.

???: " Behind you..!~ "

You turn around, you see a short boy with choppy brown hair, wearing the old uniform.
