Junpei Kousaka is a second-year high school student who has a cat allergy, which has caused him to despise cats and everything linked to them. However, he is surrounded by cat lovers: his family, an alienated childhood buddy, and even his crush Kaede Mizuno. Junpei casually attempts to kick an empty can into the garbage on his way home from school one day, but fails horribly. Instead of ending up in the trash, the can ends up severing the head of a cat goddess statue. He is cursed with the capacity to comprehend cat talking on that fateful day. However, he must keep his curse hidden from everyone else, for anybody who discovers it will grow more prone to accidents and share the curse.
