The oath of the masochist is a ceremony of the long-horned beetle. The man who participated in a topknot-cutting ceremony of the Slave which I found in a site of the BDSM of the Internet. Therefore, as for the Slave, hair is cut by men. Beat the brain of a woman considered to be a bald head, and tie up a body, and hit it with a whip, and blame you by a candle. Engrave the fate of the masochist into Kokoro in this ceremony.
