Gangsta. (ギャングスタ) is a Japanese manga series written and illustrated by Kohske. It has been published in Shinchosha’s Monthly Comic @ Bunch magazine since 2011. The series has inspired a spin-off manga, an audio drama series, and an anime television series. The manga inspired a spin-off series, titled Gangsta.:Cursed. EP_Marco Adriano, which began serialization in the fourth volume of the Quarterly Comic Go Go Bunch magazine, preceded by a prologue in the third volume, which was published on 9 April 2014. The series is illustrated by Syuhei Kamo. Gangsta.:Cursed. EP_Marco Adriano focuses on mafia staff member Marco Adriano, a character from the original manga.
The anime is set in a city controlled by various mafias, and the action mainly focuses on two characters: Nick a silent cookie cutted maniac and his companion, Worick. Not giving away too much of the story, as i understood, these two are somewhat neutral forces that work for different people, including the police. As you can see, the setting is practically the same that in Black Lagoon, a mafia/gangster infested city where a neutral company carry out jobs for money. Does it mean that its a boring copy paste? Nope. The characters are interesting so far and they display some morals.
In the city of Ergastulum, a shady ville filled with made men and petty thieves, whores on the make and cops on the take, there are some deeds too dirty for even its jaded inhabitants to touch. Enter the “Handymen,” Nic and Worick, who take care of the jobs no one else will handle. Until the day when a cop they know on the force requests their help in taking down a new gang muscling in on the territory of a top Mafia family. It seems like business (and mayhem) as usual, but the Handymen are about to find that this job is a lot more than they bargained for.
