Azuki Bean Washer.A writer of riddle books for children, Momosuke Yamaoka's ambition is to compile a book of 100 ghost stories. While traveling on business he is caught in a rain storm and seeks shelter at a local inn on the advice of a spiritualist named Mataichi. At the inn, Momosuke encounters Ogin and a monk named Enkai. Enkai was a former apprentice who apparently suffers delusions in which he hears the sound of azuki beans being washed. Mataichi arrives at the inn during the evening. The innkeeper Tokuemon shares the story of an apprentice boy of his who was murdered by Tokuemon's clerk Tatsugoro. He tells how the spirit of a boy named Yasuke haunts the inn as an Azukiarai. The tale provokes a strong reaction from Enkai, and together Mataichi, Ogin, and Nagamimi (who was Tokuemon in disguise) stoke Enkai's emotions provoking a breakdown. Enkai confesses to murdering the apprentice boy several years earlier in a fit of rage because Tokuemon intended to make the boy his heir rather than himself. He dies soon after and his body ending up in the nearby river as Mataichi commits Enkai's soul to the next world. When Momosuke encounters Mataichi, Ogin, and Nagamimi, he learns that they are the Ongyou. Before the Ongyou disappears, Mataichi warns Momosuke to keep his distance from them.
