At Outpost 7 in the wasteland, maid Mia is disfigured by zombies while saving Rio, only to be kicked into a ditch of corpses by him. Dying, she binds to the "Hyper-Dimensional Beauty Salon System" and regains her stunning looks. She opens a pink beauty salon, determined to destroy her former lover's rule. The salon becomes a huge hit; Rio pursues her while secretly having his power undermined, and Mia grows closer to Lord Ethan. When Rio discovers the truth, he unleashes a zombie horde and uses an EMP to disable her system. Ethan is severely injured. Mia awakens, using scraps to create corrosive makeup-remover bombs and laser manicure weapons to counterattack. She kicks Rio off a high tower. Finally, she heals Ethan, shares a kiss with him at the salon, and becomes the queen of the wasteland.
