Nobody talks about this one. Three episodes of pure salesman-versus-yakuza slapstick where a guy trying to close deals gets tangled up with the worst possible people, and the comedy lands because the violence is absurd enough to be funny without ever winking at the camera. It's built for people who want their action-comedy grounded in real stakes but ridiculous execution, not for viewers waiting for the next big franchise moment.
Takao Ryouta used to be a biker and now drives a bus. He is lecherous but means well, and he spends his time racing other drivers on the streets, trading blows with toughs from his past, and bullying a friend who is every bit as lecherous as he is. When thugs kidnap the woman he has feelings for, he has to step up and rescue her. The three-episode OVA from 1990 mixes action and comedy, and it adapts a manga by Murata Hiroyuki that ran in Weekly Manga Goraku, a magazine aimed mainly at salarymen.
