Kizumonogatari Part 2: Nekketsu
He needs to get the vampire back to its full form in order to be able to be a normal person again. Kiss-shot Acerola-orion Heart-under-blade did this to Koyomi Araragi. Koyomi has to fight the three vampire hunters – Dramaturgy, Episode, and Guillotinecutter – to get what he wants in order to reach his goal.
