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.

Natsume's human friend Taki can only see yokai if they walk through one of her spell circles. Although many yokai see her spells as aggressive traps, putting her at risk of their retaliation, the latest yokai to pass through her circle may have something other than revenge in his heart. But is that any better...?
