Four beautiful investigators go undercover to investigate an evil organization that amasses huge wealth through gambling, drugs, and prostitution! Trained elite investigators (Yuna Shiina, Kokoa Aisu, Hikaru Konno, Ruka Kanae) make the most of their female weapons and catch men while toying with their instincts. Conversely, even if they are caught and tortured, they will turn to evil in order to carry out their mission.
