Massacre Gun

A mafia hitman named Kuroda betrays his superiors after he is coerced into killing the woman he loves. He teams up with his brothers, a temperamental man named Eiji and a trainee boxer named Saburo, who have also suffered grievances. Their quest for revenge against the organization evolves into a wide-scale conflict over territory that continues until only one group remains.
