Natsume's Book of Friends

Natsume discovers that the heirloom "Book of Friends" that his grandmother, Reiko, gave him possesses the names of the spirits she defeated and bound to her will.

Natsume is visited by the village's local god who is currently fading because of the lack of devotees.

Natsume is implored to help spirits who are currently being exorcised. He finds a kindred spirit in Tanuma, a boy who also senses spirits although not as powerful as Natsume.

Natsume's secret is found out by Sasada, the class president, during the "Trial of Courage." She asks for his help to find the spirit that lives in the abandoned school. Natsume denies the fact that he can see anything, but she won't take no for an answer. Meanwhile, the spirit, Shigure, captures the rest of their school mates, in fury of the school being torn down...

Natsume comes across an old ticket in Reiko's belongings and decides to go to the abandoned train station to see why she kept it. There, he meets a slow witted spirit named Santo, who was waiting for Reiko the entire time to go Kiriganuma, to see and make up with his friend, Mikuri, but the trip isn't as easy as it first seems...

Natsume goes to a dam and finds a town that had been submerged in water. Just then, Natsume gets possessed by a yokai and falls unconscious.
