Takashi Natsume has always been aware of the supernatural world, but after he inherits a magical book from his grandmother, the supernatural world is aware of him!

Takashi Natsume can see the spirits and demons that hide from the rest of humanity. He has always been set apart from other people because of his gift, drifting from relative to relative, never fitting in. Now he's a troubled high school student who has come to live in the small town where his grandmother grew up. And there he discovers that he has inherited more than just the Sight from the mysterious Reiko.

A local exorcist has passed away, leaving behind a study packed with a lifetime of important yokai research. But his family are normal and don’t know where he’s hidden his workroom. Now all the exorcists in the area are on the hunt for the mysterious library. But Natsume can’t decide what is more dangerous—letting the other exorcists find the collection, or discovering it himself!
