Koyomi Araragi, a third-year high school student, survives a vampire attack thanks to the assistance of Meme Oshino, a peculiar man living in an abandoned building. Although he has been cured of vampirism and is human once more, he retains certain side effects, including superhuman healing powers and enhanced vision. Nevertheless, Araragi strives to lead the life of an ordinary student, aided by his friend and class president, Tsubasa Hanekawa. When his classmate Hitagi Senjougahara tumbles down the stairs and is caught by Araragi, he notices that she is unnaturally weightless. Despite Senjougahara's objections, Araragi insists on helping her and decides to seek the aid of Oshino, the same man who had previously assisted him with his own troubles. Through a series of stories involving demons and gods, Bakemonogatari follows Araragi as he endeavors to help those afflicted by supernatural ailments.
