Gangsta. unfolds in Ergastalum, a rotten city where mob syndicates, corrupt police, and unstable alliances decide who survives another night. In that pressure cooker, Nicholas Brown and Worick Arcangelo work as the Handymen, freelance fixers who accept the jobs nobody else wants and enforce a fragile kind of order with fists, guns, and hard-earned street sense. Their routine shifts when they protect Alex Benedetto, a woman caught in the crossfire of the city's violent factions, and she becomes part of the uneasy circle around them.
As the Handymen are pulled deeper into the conflict, Gangsta. widens its focus to the Twilights: superhuman people created by a special drug, feared for their strength, and hunted by an underground organization that treats them as disposable tools. The anime mixes crime drama, action, and urban noir while tracing the cost of survival in a city built on prejudice, exploitation, and shifting loyalties. At every turn, Ergastalum feels like a place where power is temporary, trust is dangerous, and even the smallest choice can tilt the balance between rival forces.
