Koyomi Araragi has become a vampire and her servant after assisting in the revival of the famous vampire Kiss-shot Acerola-orion Heart-under-blade. Kiss-shot is certain she can transform him back into a human, but only after recovering full strength. Araragi has tracked down the three vampire hunters who defeated Kiss-shot and recovered her limbs, allowing her to regain full strength. However, now that Araragi has almost completed what he has been battling for the entire time, he must question whether this is truly what he desires. There's no knowing what she'll do if he resurrects this strong immortal vampire, and there's no stopping her.
