Black Lagoon: Roberta's Blood Trail

A vengeful maid turns Roanapur into a blood‑soaked chessboard, and no one’s safe.

In the lawless sprawl of Roanapur, the quiet hum of a maid’s apron hides a lethal past. Roberta, once a guerrilla operative for the Venezuelan Lovelace clan, now serves as their devoted housekeeper—until a covert U.S. strike slays her commander and leaves a trail of blood. Fueled by a cold, methodical fury, she storms back into the city’s neon‑soaked underworld, hunting the foreign agents responsible for the murder. Her path of vengeance cuts through rival syndicates, mercenaries, and the ever‑watchful eyes of the U.S. military, turning the streets into a battlefield where every bullet tells a story of betrayal. Meanwhile, Fernando Garcia Lovelace, the teenage heir to the family fortune, refuses to sit idle. Accompanied by his stoic bodyguard Fabiola, he follows Roberta’s trail to Thailand, hoping to drag her back into the family’s protective fold. Desperate, he enlists the infamous Lagoon Company—Dutch, Revy, Benny, and Rock—to act as a buffer between the blood‑thirsty maid and the chaotic forces converging on Roanapur. As alliances shift and the body count climbs, the only certainty is that Roberta’s relentless quest will force everyone to choose between survival and the price of vengeance.

This OVA depicts a one-woman war of revenge with unflinching, graphic violence including torture and dismemberment. The psychological horror of a traumatized soldier's mental collapse is central, alongside heavy drug use and constant strong language.
