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.

The scene is Steam City, a London-ish city which represents an entire civilization run by coal and steam power. Because of steam, the city is sometimes covered in a mist. Villains take advantage of the steamy mist to hide and execute their evil plans. Only a few dare venture into what’s beyond the steamy mist. They are known as the Steam Detectives: Narutaki (and his convertible all-purpose pistol), his nurse-assistant Lingling, and his Megamaton robot Gohliki. (Source: ANN)
