Chikan densha: Asa kara ikasete

Kentaro, who works at a toilet company, has a crush on Junko, who rides the same train as him every morning. One morning, when he tries to confess his love to her, he is threatened by a molester and has his money stolen. The woman is Junko's older sister, Ryuko. The two are the daughters of Koji, who calls himself the number one boss in the Kanto region, and his brother, Bunta, is a strange transvestite who thinks of himself as a gigolo. Koji, who fell in love with Kentaro's personality, approves of their relationship, but by that time the gang had no more young members and was being forced to disband. Then Nobuo, the acting boss, was released from prison, and Koji lost his important name.
