Sôten no Ken

A mysterious man known as "the King of Death" roams the streets of pre-war Shanghai in this action-packed prequel to Fist of the North Star. Shanghai in the 1930s is a dangerous place. Foreign governments and Chinese factions have carved the city into different quarters, each with its own laws and government, and all rife with corruption. As the major powers vie for political control, the streets are left to local gangs. Life is cheap, and death is always near. (myanimelist.net)
