Jinpei who has solved the seven wonders of the school one after another, the last one is Hanako-san of the toilet. Immediately, when he was checking the location, the scream of Matarou who went to the toilet alone echoed! When Jinpei and the others rushed to the women's toilet, Matarou was sucked in by a tornado that came out of the toilet bowl. Jinpei and his colleagues, who thought it was Hanako-san's work, followed the road leading to the old school building where Hanako-san was there. Then a big gate appeared and they heard a voice saying, "Welcome to Morasita La Damelia."
