Kentaro is a lonely loser and geek (Otaku). When he's fired from his job, he also loses his dignity. At his lowest moment he goes out on the town to drink away his misery when he wanders into an abandoned building in the heart of the pleasure district. There he finds a pretty girl doll with skin so soft and warm to touch. Her skin is so lifelike that he can see the veins under the skin... but it is a doll without a heartbeat. In his muddled consciousness, the man sees the doll turn into a cyborg girl and save him from thugs. The doll becomes his guardian angel with a demonic twist as she fulfills his fantasies by becoming a cyborg girl, a swan-lake ballerina, and his girlfriend. This hallucinatory and erotic romance fulfills the man's final erotic desires. Who is she really? And where will their romance lead them...?
