Black Lagoon, Vol. 7 by Rei Hiroe

[Viz] Four hardcore heroes. One high-speed torpedo boat. Ten thousand bullets! Lock n' load with the baddest group of mercenaries ever to hit the high seas of Southeast Asia! Aboard their World War II torpedo boat, the Black Lagoon, Dutch the Boss, Benny the Mechanic, Revy Two Hand, and Rock, the salaryman from Japan, deliver anything, anywhere. In the dangerous underworld of the Russian Mafia, Chinese triads, Colombian drug cartels, crazed assassins, and ruthless mercenaries, it's hard to know who to trust. But if you've got a delivery to make, and you don't mind a little property damage along the way, you can count on the crew of the Black Lagoon! The shockwaves from the assassination of Garcia Lovelace's father in Venezuela hit Roanapur full force. The deadly maid and ex-terrorist Roberta begins her quest for vengeance and she's not going to quit even if the trail takes her deep into a web of intrigue involving the U.S. military. The city's criminal gangs realize the danger of too much U.S. government attention, and the crew of the Black Lagoon is drawn into the search for the renegade killer maid from Hell. But Roberta's dance of death won't be over until everyone has paid the price in blood.
