Kakouen and Kan-u are both seen, wearing S and M costumes, while Koukin, in the background, is tied up and stripped naked. Kan-u and Kakouen then begin punishing Koukin in various ways until he passes out from the pain resulting in a tie in their competition. Ryomou then bust through the door, as Kakouen makes her escape unseen by anyone. Ryomou then collects Koukin and vows revenge on Kan-u as she leaves the scene, with Koukin on her back.
