In the second season, known as Black Lagoon: The Second Barrage, Shogakukan was not involved in the production. The English adaptation of the episodes is licensed by Geneon Entertainment. The plot of the episodes follows the adventures of a Japanese businessman, Rokuro Okajima, after he is abducted by the members of the ship Black Lagoon and joins their crew under the moniker "Rock".
