Third year high school student Koyomi Araragi seems ordinary, but he was recently saved from being an involuntary vampire by a mysterious homeless man named Meme Oshino. He is still scared of morning sunlight even though it no longer has any effect on him.
Koyomi becomes involved with an aloof classmate, Hitagi Senjougahara, who infamously never talks to anyone, happens to fall down some spiral stairs and into Koyomi’s arms. Koyomi is surprised because, in defiance of physics, Hitagi appears to weigh almost nothing at all.
After Koyomi tries to find out some information about Hitagi from class president Hanekawa Tsubasa, Hitagi accosts Koyomi in an empty school hallway and threatens him with a box cutter and a stapler that she shoves into his mouth.
Hitagi explains that a supernatural crab took away her weight, orders Koyomi to keep quiet about her, and emphasizes the order by driving a staple into Koyomi’s cheek.
But Koyomi removes the staple and quickly confronts Hitagi again, letting her see that the staple wound healed immediately and telling her about his time as a vampire.
Koyomi then takes Hitagi to meet Oshino in the hopes that Oshino may be able to help Hitagi with her problem.
Koyomi Araragi is a third year high school student who is close to failing every class except math.
