Neko, Hajimemashita: Nyantomo Kininaru Nyao

Nao Kazushiro is a normal high school student—until he gets in a traffic accident and winds up in the body of a cat! At first, it's all fun and games as he gets used to his new form, but then the novelty wears off and the hunger sets in. Luckily, he's picked up by Chika, a girl his age, who gives him food and a home off the streets. She's paw-fully sweet and pretty, but meanwhile he's still in a furry feline body! Will Nao (now Nyao) ever get his human form back, or will fur end up flying instead of sparks?
