[Mosaic removed] An anachronistic coming of age ritual that is still passed down in Y City, Yama○ Prefecture. It involved an adultery ritual in which the daughter of a family sacrificed her virginity to an elder relative of hers. Her daughter, who had gone to Tokyo and lost her virginity, has her hands and feet bound and is punished for breaking her clan's rules. She was made to drink an aphrodisiac, and she lost her sense of self, drooling, and was forced to straddle her father and keep shaking her hips.
