Koyomi Araragi was turned into a vampire by the legendary vampire, Kiss-shot Acerola-orion Heart-under-blade, and he needs to revive the weakened vampire back to her complete form to return to being human again. The only way for Koyomi to achieve his goal is to fight the three vampire hunters – Dramaturgy, Episode and Guillotinecutter.

“I think it’s about time I talked about Kiss-Shot-Acerola-Orion Heart-Under-Blade. I believe it’s something I have to do. I met her in the spring break between my second and third years of high school. That meeting had such impact and was also quite devastating.”

One fateful evening, second year high school student Koyomi Araragi has a shocking meeting with Kiss-shot Acerola-orion Heart-under-blade, the “King of Apparitions.” She was blindingly beautiful, yet chillingly terrifying. She was a painfully merciless, legendary vampire, with missing limbs. Kiss-shot asks Koyomi to give her his blood in order to save her life, and when he does, the very next moment he awakes, Koyomi finds himself re-born as her vampire kin.
