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.

Under Igo's supervision, Kintaro is thrown in at the deep end at a contract bid and finds bureaucracy is an enemy that maybe even he can't beat.
