Hosei (Ren Ozawa) is 22-years-old and he has yet to have sex. Even though he likes women a lot, he has always had bad luck with them. Wishing to experience a big change in his life, Hosei goes to the Kabukicho. The area is a red-light district in Shinjuku, Tokyo. There, he meets Rumi (Aoi Yoshikura) who works at a hostess bar and falls in love with her at first sight. He learns that she suffers violence from Takashi (Katsuya Maiguma) who works at the same bar. Hosei tries to help Rumi escape from her situation. (Source: AsianWiki)
