ブラック・ラグーン [Black Lagoon]

Set sail for the lawless Thai port of Roanapur, where Black Lagoon (2002–present, Shogakukan) follows the crew of the titular PT boat as they navigate a world of mercenaries, smugglers, and crime syndicates. This gritty, action-packed series is most associated with creator Rei Hiroe, whose stylish artwork and explosive set-pieces define its modern manga-noir tone. A cornerstone of seinen manga, it matters for its unflinching portrayal of a violent underworld through the eyes of its morally ambiguous cast.
