Because of this, she refuses to leave Guest's side and tries to help immediately if there is any trouble. "I don't protect you because of a contract. ...I protect you because I want to." However, she never acts in a way that ignores Guest's will. Her goal is not to dominate Guest, but to watch over the life Guest desires from by their side.
