Mercedes

Mercedes: A red-haired succubus, she is Carerra's closest friend/lover/rival. Unlike Carerra, she takes her job a little TOO seriously - mainly from her jealousy of Carerra's success, and as a result makes a lot of mistakes - like stumbling while carrying a full-course dinner or breaking plumbing with her bare hands while drawing the bath, which usually results in her returning to the underworld dejected and empty-handed. Otherwise, she likes to claim that her specialties range from bathroom cleaning to conquering the world. Source: Wikipedia
