The super flexible beauty "Maeno Nana" is sacrificed in real iron restraints from medieval Europe, immobilizing her. She is restrained in an impossible position that completely ignores the structure of the human body, and the torture play begins with her exposed, shaved pussy. Her face is slapped and a nose hook is used, her body is whipped with rose whips and nipple clips, and her vagina is attacked one after another with various toys and huge cocks. The intense torture and restraint poses are among the most intense in the series, and both Kokoro and her pussy are sure to fall into darkness.
