Travel across a dangerous world filled with frenzied monster girls suffering from a virus which makes them attack men and become sex crazed. Humans live in fear, conflict happens often and monster girls invade towns and villages to attack the men. Any man that fails to protect himself and is 'finished' by a monster girl contracts the virus and becomes her slave until she either uses him up or kills him/eats him. Monster girls are ostracised from society, even those who are not infected. Forced to live in secret and with a human civilization hungry for revenge, war brews on the horizon.
