The story of a high school girl and a certain part of her body that has turned into a monster. A horrifying and erotic story from the mad mind of Noboru Iguchi (THE MACHINE GIRL, KARATE ROBO-ZABORGAR).

Koga is a wimp and is being bullied at school even by a girl. Soejima comes to his defense, but is now a target of the two bullies as well. Koga and Soejima are attracted to one another. Is it their mutual victimhood or actual love or could those two things be one and the same in this case?
