It has been a year since Rock joined the crew of the Black Lagoon, and while becoming accustomed to life in Roanapur, he also gets involved in many dangerous circles. With the level of violence increasing by the day, Hotel Moscow takes advantage of Rock's talents, and he soon finds himself intimately involved in their struggle for power. A series of events eventually lead Rock back to Japan as a translator for Balalaika, where he soon finds himself confronted with the choice of returning to his old life or continuing with the new. While questioning where his morals lie, Rock must decide, once and for all, whether or not to call the Black Lagoon home.
