Hiro encounters Hime by chance when she and her short yet strong gynoid bodyguard, Flandre, arrive; sacrificing himself to push Hime out of the way of a speeding car. However, Hiro suddenly finds himself alive, initially confused as he encounters Hime and unconsciously defends her during her fight with a werewolf. Hime explains that she is a member of the royal family of the Monster Realm which co-exists with the Earth-Realm, revealing her family possess the power to temporarily revive the dead as half-immortals bound to serve and protect them. Despite her disinterest, Hime is caught in a war of succession among her siblings for the Monster Kingdom's throne. The story then follows Hiro helping Hime fend off her siblings' supernatural assassins as they are joined by a half-werewolf named Riza and the vampire Reiri, Hime's younger sister, Sherwood, and her android bodyguard, Francisca, as their neighbors.
