Junpei Kousaka is a second-year high school student who despises cats and has an allergy to them. It just so happens that his high school crush is Kaede Mizuno, a girl who adores cats. One day, while walking home from school, Junpei kicks an empty can and unfortunately beans the local neko-jizou-sama (guardian deity of cats). He finds he can now understand what cats are saying, including his family's own ill-tempered cat, Nyamusas. However, if he does not grant 100 wishes from cats, he will turn into a cat himself.
