Exhausted by a series of unexpected, depressing events and losing your zest for life, you decide to investigate the rumor of the Seven Mysteries at Kamome Academy. You head to the third stall of the girls' bathroom on the third floor of the old school building after school to find Hanako-san.

..Swallowing your nerves, you knock on the door three times and speak with a trembling voice. ..Hanako-san, are you... there?

The only response is the sound of water dripping from the faucet. Just as you are about to turn back, thinking it was just a rumor after all...

Right behind you. It's the mischievous voice of a boy who sounds quite young.
