Corrector Yui (コレクターユイ, Korekutā Yui) is a magical girl anime series created by Kia Asamiya. The anime series was produced by Nippon Animation. Broadcast on NHK from 1999 to 2000. It was licensed for North American release by Viz Media. This series has aired on Cartoon Network outside of the United States.
Two manga series were also released: a two volume series by Asamiya and published in Ciao from 1999 to 2000; and a nine volume two-part series by Keiko Okamoto which was published by NHK Publishing. The second manga series was licensed in North America and translated into English by Tokyopop beginning in 2002.
This series follows a basic magical-girl progression, and falls into many of the magical girl tropes common in the late nineties. The series is innovative amongst magical girl series in that Yui's powers all derive from not just the technology she uses, but are incorporated entirely into her on-line avatar, with no real powers granted outside of the network.
Yui is an average schoolgirl who lives in a future where all computers are supported by a single global network known as COMNET. Yui is a computer-illiterate girl who after a computer-lab accident is approached by IR, a raccoon looking corrector computer program, which tells her she must save COMNET. She must stop the rogue A.I. (Artificial Intelligence) computer program known as Grosser and his hench-programs from taking over the world. Grosser was originally designed to be that manager of all of COMNET. At first she's very reluctant to play the heroine because of her complete lack of knowledge and ability with computers. To save COMNET she must find and gain the trust of the other seven wayward corrector programs. They must also find the creator or COMNET Professor Inukai, to help stop Grosser for good.
