Rokuro Okajima is a Japanese salaryman employed by Asahi Industries in Tokyo. While on a business assignment, he is captured by the Lagoon Company, a crew of pirate mercenaries operating an Elco-type PT boat named Black Lagoon, which specializes in smuggling operations throughout Southeast Asia.
The group consists of Dutch, an African-American veteran of the U.S. Navy who serves as the captain; Revy, a Chinese-American markswoman and the crew's primary combatant; and Benny, a Jewish-American mechanic and electronics expert who handles technical operations. Left to the whims of his captors after his managers refuse to pay his ransom, Rokuro does the unthinkable: instead of begging for his life, he joins the very crew who kidnapped him.
Now a member of the group, Rokuro must adjust to his new residence in the dissolute hellscape known as Roanapur, a city where corruption and crime run rampant, and even the smallest slipup could cost him his life.
As Rokuro struggles to abandon his past—and with more than just the profits from the Lagoon Company's illegal trading on the line—he must quickly find the resolve to make tough decisions in high-stress situations while keeping his humanity intact.
