At the bottom of the neon sea of Greater Tokyo, an organization stirred in the deep darkness. It targeted beautiful women who, due to unavoidable circumstances, had abandoned their names and discarded their humanity, volunteering to become livestock slaves. This was a group of professional trainers who stimulated and honed their innate masochistic qualities to the extreme. One woman, Ryoko Katagiri, resolved herself and threw her body into the harsh scene. Nose torture, sadistic abuse, hard nine-tailed whip, forced enema and excretion, and confinement in a bitch cage. Yet, her body and mind gradually grew accustomed to the abhorrent pain of being a livestock slave.
