Sex Detective is back! Shoichi Yokoyama, who made a brilliant debut with his previous work “Sex Detective Hatenashi”, creates a spin-off starring Nana, the cute sidekick of Hatenashi.
Karin, a sex 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 sex with the New York Police Department Kasumi. Nana aims to solve the case with a newcomer China Girl Hachi and pseudo-sex detectives who are a reserve army of sex 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.
