Black Lagoon: Roberta's Blood Trail - Season 1 (2010)

Roberta's employer, Diego Lovelace, was killed, apparently as part of a war between the CIA and the NSA. She vows to punish those responsible no matter what it takes. Fabiola (her understudy), Black Lagoon and Mr. Chang get drawn into the conflict.

Rock accepts the offer to find Roberta before she declares war on the US troops. He tries to solve the puzzle of Roberta's whereabouts, by collecting partial information from everywhere. At the same time, the City Ring (Hong Kong Triad, Hotel Moscow, Italian Mafia, and Colombian Cartel) gather to decide upon what they should do next. The decision is kept secret, but we see Mr. Chang goes to the Church of Violence and is filled in by a CIA member (Eda) about the recent movements of NSA commandos (Alpha, Bravo, and Charlie companies).

Rock and Revy manage to track down Roberta, but it's too late to stop the war. Later, Garcia is severely traumatized by witnessing the brutality of his beloved maid in action.
