Mirei Nitta is chosen as the sacrificial offering for her 21st appearance, exposing her pure and innocent form. Her body is locked into iron restraints, completely stripped of freedom. Her face and nipples are tormented as an anal hook is driven in, followed by a brutal whipping while intense anal fucking commences simultaneously. As her body gradually reaches its limit, her anus is forcibly stretched using expansion pumps and various toys. Suspended in midair, she is subjected to extreme conditions as three or more men penetrate her anally. Further tormented with hot wax dripping onto her skin, she undergoes relentless enema torture, with mysterious fluids repeatedly injected into her rectum, driving her body to the absolute brink. Finally, facing her own reflection, she experiences a self-destructive, explosive climax, releasing everything.
