Bakemonogatari S01

Araragi is a third-year student who survives a vampire attack during his spring break, but the attack causes changes in him, such as being able to see in the dark or his wounds healing quickly. One day, as he is climbing the stairs in school, he saves a classmate from falling, but to his surprise, he finds out that the girl is weightless due to an encounter with a mysterious crab. The girl in our story, who is afraid of her secret being revealed, threatens Araragi that if he reveals her weightlessness secret, he will be in trouble. The story becomes more complicated with the introduction of the third main character, Oshino, a middle-aged man who has the ability to solve problems caused by supernatural creatures.
