Revy is a sadistic killer who shows no mercy to her enemies. Of all of the characters in the series, Revy uses the foulest language. She takes maniacal glee in killing anyone and everyone. She has a changing but volatile attitude towards Rock, the newest and most humble crew member of the Black Lagoon; though she respects him later in the series, she is mostly hostile towards him. Constantly living on the edge of life, Revy has developed a rather bleak, almost nihilistic outlook on life.
