First appearance in the "SM Prison Cell" series! A documentary-style work capturing the abnormal pleasure born at the edge of madness. In a brutal training ritual held in an underground dungeon, female prisoners surrender their captive minds and bodies. As humiliation, shame, pain, and pleasure intertwine, the women's hidden masochistic desires are exposed. This release fully documents the extreme discipline endured by the exquisite-bodied woman introduced as "Prisoner #001, Chinatsu." Through a ceremony filled with the ecstasy of suffering, her complete surrender and intoxication are vividly portrayed.
