Lady is a character from the Devil May Cry series of games, with her first appearance being Devil May Cry 3: Dante's Awakening. She was born with the name Mary, but she renounced that name when her father, Arkham, killed her mother in order to become a demon. She became a Devil Hunter because of that, with her goal being to eliminate every last demon.
She uses a rocket launcher, named the Kalina Ann, as her primary weapon. It has her mother's name etched into the handle and the bayonet can be used as a grappling hook or melee weapon. Lady has a fierce and rough personality, although she tends to show a softer side when around Dante, on whom she seems to have a crush. This is evident when Trish is around, as she shows some jealousy.
