Satome Kazuya, a student at the prestigious Osza no Mizu Industries University, was never good with girls. The cute girl who lives next door continually teases him, and he pays no mind. Instead, he`s absorbed in his work, creating an Octopus robot that uses advanced artificial intelligence. One day, his boisterous rival gives him a mysterious CD-ROM that contains a virus intended to destroy his computer and ruin his work. The CD takes him instead to a website where he accidentally orders May - a 4-inch robot girl designed to help out around the house.
