Momosuke Yamaoka, a writer of riddle books for children, wants to compile a book of 100 ghost stories. He is caught in a rain storm while on business in the mountains and meets the spiritualist Mataichi, who advises him to leave for his own safety. Momosuke proceeds anyway and seeks shelter at a rundown shop. He encounters a monk named Enkai and Ogin. Enkai was a former apprentice who suffers delusions of hearing the sound of red beans being washed. Mataichi later arrives at the inn. The shopkeeper Tokuemon shares the story of his beloved apprentice boy Yasuke who was murdered by his previous clerk Tatsugoro; the boy's soul now haunts the place as an Azukiarai. The story greatly affects Enkai. Later on Mataichi, Ogin, and Nagamimi (disguised as Tokuemon) stoke Enkai's emotions which sends into a breakdown. Enkai confesses that he murdered the apprentice boy several years earlier out of rage because Tokuemon wanted to make the boy his heir rather than himself. He dies soon after and his body found in the nearby river, where Mataichi commits Enkai's soul to the next world. When Momosuke finds Mataichi, Ogin, and Nagamimi, he learns that they are the Ongyou. Mataichi warns Momosuke to keep his distance from them, after which they vanish leaving Momosuke.
