Black Lagoon: Roberta`s Blood Trail

"Black Lagoon: Roberta's Blood Trail" is the third season of the "Black Lagoon" series, released as an OVA. The story centers on Roberta, the maid serving the Lovelace family in Venezuela. When the head of the Lovelace family is assassinated, Roberta transforms into a vengeful "bloodhound," embarking on a bloody path of revenge. She tracks the assassins to Roanapur, while the new patriarch, Garcia Lovelace, and Roberta's apprentice, Fabiola Iglesias, follow, attempting to halt her rampage. Meanwhile, various factions in Roanapur, including the Lagoon Company, and overseas forces get involved, escalating tensions and threatening to erupt into all-out war. Roberta's transformation from a loyal maid into a vengeful killing machine, fueled by grief and anger, drives the plot. The series focuses more on character development and world-building, resulting in a slower pace compared to previous installments.
