Salaryman Kintaro
Kintarō Yajima used to be the leader of a feared and respected biker gang, but out of respect for his late wife he chooses to straighten himself out and work as a salaryman so that he can support his son.

Much to his own company's surprise, Kintaro looks certain to win a lucrative contract but runs headfirst into the bureaucracy of city hall and the fearsome Hokuto General Construction.
