In the year 2020, computers are everywhere. From digital teachers to cars that drive themselves, computers are an integral part of everyone's lives-- everyone except Yui Kasuga's. The 14-year-old daydreamer can't tell a Pentium chip from a Dorito! How ironic that the fate of the internet, and the world, should fall on the sholders of this young girl. When the sentient computer virus, Grosser, infects the global network Com-Net, Yui is transported into cyberspace to combat his evil plans. Only by assembling the eight missing pieces of the corrector program can Yui make the Net safe once more. A dangerous quest, fabulous costumes, a cute sidekick... Yui's superhero dreams are about to come true where she least expected it!
