In Black Lagoon, Okajima Rokuro, or as he's more commonly known in Roanapur, "Rock," was a Japanese salaryman who was kidnapped by the Lagoon Company and then betrayed by his company, Asahi Heavy Industries, who sent a band of mercenaries to kill him. Rock has since joined his kidnappers, acting as the Lagoon Company's general negotiator. His idealism, his sense of morality and his willingness to settle things with words rather than guns often puts him at odds with the more violent and cynical Revy.
