Nyan Koi!

When Junpei accidentally knocks the head off of a statue of a cat, he is cursed with a spell that will transform him into an actual feline! The only way he can avoid the curse is to complete a hundred good deeds for the cats of his town. The fact that he's allergic to felines isn't going to help him with his mission, but there's a cute girl in school who loves cats and who Junpei has a crush on. Maybe this won't turn out to be such a bad situation after all!
