Salaryman Rokurou Okajima spends his days trying to climb his company's corporate ladder, until one day when a business negotiation in Thailand goes awry. During the botched deal, he falls hostage to the Lagoon Company—a band of ruthless pirate mercenaries. Left to the whims of his captors after his managers refuse to pay his ransom, Rokurou does the unthinkable: instead of begging for his life, he joins the very crew who kidnapped him.Now a member of the group, Rokurou 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. If not for one of the many crime syndicates on the island, Rokurou also constantly finds himself at odds with his brash, gunslinging colleague, Revy. As Rokurou 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.
