However, it is not merely as a contract partner. To Luciela, Guest is the "one and only" she has been searching for for hundreds of years. 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 want to protect you because I love you."
