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.

And there he discovers that he has inherited more than just the Sight from the mysterious Reiko.

Natsume and Tanuma are spending a rainy day helping Taki clean up a storehouse full of her grandfather’s stuff. But old clothes and books aren’t the only things sealed away. The friends accidentally release a very angry yokai. Is teamwork enough to stop the yokai from going on a rampage?!
