Black Lagoon is a Japanese manga series written and illustrated by Rei Hiroe. It has been published in Shogakukan’s seinen manga magazine Monthly Sunday Gene-X since April 2002, with its chapters collected in 12 tankōbon volumes as of August 2021.
Rokuro Okajima is just an average Japanese salaryman, living an average life. But when he’s taken hostage by the crew of the Black Lagoon, Rokuro finds himself thrown headfirst into a deadly world of outlawed heroes, brutal villains, and blazing gunfights. Where he ends up is anyone’s guess, but one thing is for certain—he’s in for a wild ride!
