Black Lagoon: Shaitane Badi

A former Japanese businessman, Rock becomes involved with the "Lagoon Company," a group that transports goods and occasionally engages in piracy. Alongside Dutch, Revy, and Benny, he operates from the nearly war-torn city of Roanapur, a hub for international criminal organizations. The city is loosely governed by powerful figures like Balalaika and Chang. The story takes place shortly before Rock is set to return to Japan with Revy. It focuses on former soldiers who once fought together in a desert region, and the personal reunion of a captain with a former subordinate.
