* Based on a series of light novels written by Nishio Ishin and illustrated by Vofan. Araragi Koyomi is a third year high school student who is almost human again after having briefly become a vampire. One day, a classmate named Senjougahara Hitagi, who infamously never talks to anyone, falls down the stairs into Koyomi's arms. He discovers that Hitagi weighs next to nothing, in defiance of physics and common sense alike. Despite being threatened by her, Koyomi offers her help, and introduces her to Oshino Meme, a middle-aged homeless man who helped him stop being a vampire. Note: Episodes 13-15 (Tsubasa Cat parts 3-5) were not part of the initial TV broadcast and premiered on the anime's official website.
