Mana goes to Cat-girl saying, "lately, creepy things have been happening at school." After learning that one of the seven wonders of Mana's school, Hanako-san of the third floor girl's bathroom, is a friend of Cat-girl's, the two of them go to see Hanako, but they can't find her. And it's not just her. None of the yokai of the other seven wonders has been seen lately. Just then, the Sand-throwing Hag and Child's-cry Old Man arrive, having not been able to contact their old friend Ninomiya Kinjirou. They sense someone's presence and chase after it, all the way to the boy's bathroom on the second floor... What is happening at the school?!
