Hideo, a brilliant yet socially inept and reclusive shut-in, has not left his parents' basement apartment in 13 years. To combat his loneliness while still avoiding all human contact, he has spent years constructing a female humanoid robot to be his de facto girlfriend. The completion of Hideo's steely sweetheart is an exciting event... that is, until she awakens and behaves completely differently from the way he programmed her.

Not keen on the idea of serving forever as the plaything of a perverse basement-dweller, Hideo's would-be mechanical mistress takes charge of the bizarre situation she's been wired into. When she forces Hideo to face his worst fear - the outside world - things start to get ugly, and fast. Soon enough, Hideo finds himself embroiled in the devious plans of an organization of sinister yet eerily familiar people, whose ultimate goal has implications not just for his own island nation, but the rest of the world of tomorrow as well. It's a darkly humorous adventure in which one man sees his wildest dreams come gloriously true and crumble spectacularly at the same time... the only upside is that they may have just been childish fantasies all along.
