Kazuto is an ordinary fellow trying to run his grandfather's bathhouse when he's accidentally killed by the warrior Princess Valkyrie. Sacrificing half of her own soul to bring Kazuto back to life, Valkyrie is transformed into an 8-year-old girl. In this installment of the offbeat anime, the pair prepares for their pending nuptials, but, of course, there are plenty of forces on hand to throw a wrench in the wedding plans.
