Corrector Yui

A schoolgirl gains self-confidence, new friends, and a cache of chic outfits when she becomes the computer-programming magical girl, Corrector Yui. She must stop the rogue A.I. Gurossa (Artificial Intelligence computer program) and his hench-programs from taking control of the global computer network. In this future, all human activity is supported by computers, so it's possible to control the world using the network. (Source: MU)
