Walking home from the store one night Koyomi Araragi finds a vampire on the verge of death, and against his better judgement he decides to sacrifice himself so that she can survive. He does not die however. Instead, she transforms him into a vampire and tasks him with recovering her lost limbs from the hunters who stole them.
A prequel to Bakemonogatari, this series of movies fully fleshes out the brief flashback you get there. Content composition is similar with the main difference being that a larger percentage is dedicated to action and horror.
