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.

Nyanko Sensei hasn't been home in days, and Natsume is starting to get worried. He knows Sensei left in a party mood, but he has no idea where his friend and bodyguard was headed. And now there are rumors of evil spirits from the east heading to the local forest. Will Natsume have to face this threat all on his own?
