Koyomi Araragi, no longer completely human, embarks on a quest to reclaim Kiss-shot Acerola-orion Heart-under-blade's dismembered body, which was snatched by three formidable vampire hunters. His opponents include a vampire hunter who is also a vampire - Dramaturgie, a semi-vampire who can transform into mist - Episode, and the most dangerous of them all, a human priest known as Guillotinecutter. Unaware that every moment spent in pursuit of Kiss-shot's missing limbs further diminishes his humanity and enhances his vampire essence, Araragi must confront the perilous reality. Will he succeed in regaining his lost humanity after these battles are over, or will his wish slip out of his reach?
