ONGP-027 Undercover investigator Yuna Shinami, Shina Aisu, Hikaru Konno, Ruka Kamei

Four beautiful investigators go undercover into an evil organization that amasses huge wealth through gambling, drugs, and prostitution! Trained elite investigators (Yuna Shiina, Kokoa Aisu, Hikaru Konno, and 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.
