Some strong violence is present, especially in the last three episodes.
A man is tortured by having his arms and legs cuffed around a metal barrel, with his torturer dropping hot coals into it. It's later revealed that the place burned down with him still inside it.
A wounded soldier is promised to be taken to the hospital in exchange for information, however when he gives the information he is quickly shot dead. Bound to upset some viewers.
A man and a woman are about to have sex in the middle of a war zone, only for the woman to shoot needles from her belt buckle and finish the man off with numerous punches to the head that eventually transform his head into a pile of human mulch.
In several flashbacks to Vietnam, a bunch of U.S. soldiers standing in a destroyed village terrorize a little girl with the intent of raping her, but one of the soldiers intervenes and saves her.
A group of U.S. soldiers are searching for Roberta in the jungle, and Roberta hunts them while they hunt her. The ensuing chaos is brutal and intense, with spikes and snipers dealing the most damage/deaths.
Episode 3 is the most violent, with guerrilla warfare between the Russian mob, the Lagoon Company+a few allies, a group of bounty hunters, U.S. soldiers, and Roberta herself all clashing in the streets of Roanapur. People are blasted apart in graphic detail by anti-material rifles and explosive charges; other graphic deaths include chainsaws, knives, pistols, grenades, wires, bazookas, and snipers--all of which lasts for most of this episode and a good portion of Episode 4, and is insanely violent. The series doesn't let up on the brutality--in fact, this episode may even put the Bloodsport Fairytale episodes in the 2nd Season to shame with how bloody, disturbing, and violent it is. It should also be noted that the graphic nature of the violence in this OVA is even more intense than anything that was in the show.
