Hitoshi Kobe is rather unintelligent, unathletic, and extremely unpopular. The only thing he is truly skilled at is developing artificial intelligence programs on his computer. His magnum opus is Unit 30, which very accurately simulates conversation with a real girl. One dark and stormy night, a freak lightning strike causes Unit Thirty to emerge from his computer screen as a living girl, sending Hitoshi's life on a crazy turn.
