The Gun Like Lightning

Original title: 拳銃無頼帖　電光石火の男

A young yakuza just released from prison for a crime he didn't commit, a police inspector determined to clean up the corruption in his own hometown, and a deranged assassin who lives to kill collide in a port town overrun by rival gangs, with two women, both stuck in relationships they are trying to escape from, stuck in-between.
