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, its all fun and games as he gets used to his new feline form, but then the novelty wears off and hunger sets in. Luckily, hes picked up by Chika, a cute girl his age who gives him food and a home off the streets. Will Nao (now Nyao) develop feelings for her? Or will he wake up in his human body once and for all?
