Souichiro Hino's mother may be a world famous psychic, but she sure has trouble keeping track of everyday details. For example, that 'wonderful' new school she sent him to was embroiled in a string of grisly murders. All of the victims were male students like Souichiro. Nor did she mention that fellow psychic and childhood friend, Itsuki Aoyama, attended the school and was expecting him to do something about all of that. And then there was Itsuki's Love Club, also known as the Ghostbusters. Somehow, his friend had gotten it into his head that a random group of kids – and one friendly spirit of a dead honor student – could take on and defeat The Seven Mysteries of Seika Academy, which actually numbered ten or more. Souichiro didn't have time to object. There was a killer Sakura tree in the garden and a portal to hell in the Emergency Stairwell. If all of this wasn't bad enough, there was that 'connection' between him and Itsuki. They hadn't seen each other for years, yet everyone treated them like a couple! Souko Hino sure had a lot of explaining to do!
