Natsume's Book of Friends

Natsume has the ability to see yokai, mysterious beings that are invisible to most people. One day, he accidentally breaks the seal around a lucky cat statue, releasing a yokai named Madara who tells him about his grandmother Reiko's 'Book of Friends.'

A yokai who lives in Yatsuhara comes to Natsume to ask him to capture a human. At the same time, a classmate who recently moved to Yatsuhara named Tanuma starts asking about Natsume. Discovering that another person can see yokai rattles Natsume.

Natsume and his classmates decide to go ghost hunting at the old school building, but Natsume's classmates start disappearing. Natsume is really worried about his classmates, but in the meantime, the class president, Sasada, has a favor to ask of Natsume.

Natsume finds a train ticket among Reiko's belongings. He goes to the station that's written on the ticket, where he meets a hairy yokai named Santo, who is waiting for Reiko. When Natsume gives Santo his name back, he learns more about Reiko's feelings.

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. The yokai tells Natsume it wants to meet a certain person one last time before the town gets submerged again.
