Bathing etiquette at a public bath. Recently, the number of women who cannot abide by this has been rapidly increasing. In order to give heavenly blessings to such stupid women, a group of chivalrous social reform pranks infiltrates the women's bath of a public bath! They pass an electric current through the bathtub to make them pass out and do erotic things, attach a trim to the scale so they can't move, and enjoy electric massage and mass massage in a massage chair.
