Roberta is the head maid of the Lovelace family, one of the thirteen richest families of South America. She is very dedicated to her master Diego Lovelace and her young master Garcia. She is also one of the deadliest women alive, and used to be known as Rosarita Cisneros, the "Bloodhound of Florencia," a military-trained assassin who used to work for FARC and was a very cold-blooded killer who is now seeking to atone for her sins. She is one of the few characters of Black Lagoon capable of matching Revy herself gun for gun.
