By day, Kanade and her new step-mother Misato play happy family, half a year after Misato married into the house. By night they are sworn enemies: a magical girl against the villain sent to break her. When Misato finally corners her with the one weapon that undoes her, their battle of wills collapses into a forbidden, heated tangle that neither mother nor daughter can call off. Original title: 母子性戦 (Boshi Seisen).
