Junpei Kōsaka is a 2nd-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-jizō-sama (guardian deity of cats). Soon, he finds he can now understand what cats are saying, including his family’s own ill-tempered cat, Nyamusasu. However, if he doesn't grant 100 wishes from cats, he'll turn into a cat himself. What do you Justdubians think of Nyan Koi!?
