Gangsta is a Japanese manga series written and illustrated by Kohske. It has been published in Shinchosha's Monthly Comic @ Bunch magazine since 2010.

The series revolves around two "handymen" who take on jobs for both the mob and the police force that no one else can handle. The two, named Nicolas Brown and Worick Arcangelo, work in the town of Ergastulum, which is full of mafia, hoodlums, prostitutes, and dirty cops.
