An anachronistic coming-of-age ritual that is still handed down in Y city, Yama ○ prefecture. The content was an adultery ritual in which the clan's daughter dedicated her virginity to her relatives' elders. The daughter, who had lost her virginity after moving to Tokyo, was tied up in her limbs and was tainted for breaking the rules of the clan. After being drunk with an aphrodisiac, she lost her self and was forced to hang down and keep shaking her hips over her father.
