Both series are set in an almost identical place, with a city overrun by a variety of criminal organizations who struggle for the control of it. However, the path taken by each series is different. Gungrave starts off by exploring the past of the character Brandon Heat and later on his ressurection and revenge against the syndicate known as Millenion while Black Lagoon develops around a small group, consisting of Revy, Rock, Dutch and Benny, with the name of Lagoon Company and how they carry their jobs given by other major syndicates. Despite this both involve guns, fights, characters that will surely get 'stuck' in
