Karin, a *** detective, and Nana, an assistant, have protected the peace of Shimbashi based in a Chinese-style oil beauty salon. In the city, a mysterious incident occurs in which women disappear one after another, but Karin is not so absorbed in having *** with the New York Police Department Kasumi. Nana aims to solve the case with a newcomer China Girl Hachi and pseudo-*** detectives who are a reserve army of *** detectives. As the investigation continues, the shadow of a male office worker who is envious of his female boss, as well as the super-male and female criminal association ADAM, begins to flicker.
