An angel who has come to Earth in the form of a black cat on a mission to spread happiness throughout the world. Unfortunately he is unable to communicate with humans (who hear his speech as cat noises), and even more unfortunately for him Kiko adopts him. Even more problematically, he falls hopelessly in love with a vain female cat named Rosa, who eventually reciprocates his affection long enough to bear a litter of five kittens, who she leaves to his (and, without her knowledge, Kiko's) care.
