Tomohisa has some memory of his childhood. When he was a kid, he was often playing at some place near his house. But his parents don't remember it. Tomohisa doesn't remember it clearly, either. One day, he finds a notebook. It is about history and things happened at a small town. It's just eccentric, so no one pays attention to it. But he knows who wrote it. It's his uncle, who has been missing for years. The notebook includes a town he spent his childhood. He soon gets interested in the town and decides to visit there. Days later, he arrives at the town, but there are a lot of strange things and customs in the town. He finds various curious goods there and gradually gets to know a secret of the town and his past....
