Rosalie

Despite being member of a perverse organization, Rosalie seems to be a polite and loyal woman, as shown when Killed told her to don't lay a finger on Heidi and she gladly understood the request. Whether such behavior only appears when she's near other Mavro is unknown, but she didn't manifested any grudge or hate towards humans; contrariwise, she praised Heidi for making Killed bleed and seemingly recalled him from somewhere. She's also quiet, as she observed the entire battle to only appear when it was finished to call Killed for a dinner party. someone has finished something important, like when Killed finished his battle with Heidi.
