On her first date with the cutest boy in school, Ichigo is zapped by a mysterious ray that scrambles her DNA with that of the endangered Iriomote wildcat. The next day, Ichigo discovers that she has developed the agility (and occasionally the ears and tail) of a cat, as well as the power to transform into a pink-haired superheroine, Mew Ichigo. She and four other girls, each endowed with the genes of a different "Red Data" animal, have been selected for the top-secret Mew Project, which aims to protect the Earth from an alien menace known as Deep Blue.
Kimihiro Watanuki is a high school student plagued by ayakashi spirits, both of which are invisible to everyone else but him. The series begins when Watanuki stumbles, seemingly by chance, into a shop that grants wishes. The shop is owned by Yūko Ichihara, a mysterious witch of many names and esoteric renown. For a price, she offers to grant Watanuki's wish to be rid of the spirits. The price, according to Yūko, must be of equal value; so, as payment, he must become Yūko's temporary, part-time cook and housekeeper.
