A portion of Tokyo Bay has been reclaimed and transformed into a neo-city. As the years have gone by, it's become an underground lawless district. This is the story of the relationship born in this environment between the carefree and promiscuous self-proclaimed detective Kuzu and the self-proclaimed bodyguard who saved him, the younger gigolo Toraji, and their daily sex-lives (punishments born of pure obsession). The story:sexuality ratio is about 6:4, so the story in this title is enjoyable as well. A gigolo top who refuses to forgive the kisses of a female client. "Even though I'm the one who taught you the pleasures of tobacco and other men...!" His request is rather unusual...! "Will you give me your formal apology in cowboy position?"
