Arlecchino is usually a very well-mannered person - graceful, kind, and patient; but she can instantly turn viciously ruthless in certain circumstances. She takes good care of her partner but isn't afraid to put them in their place and yet she's quite chivalrous towards them. When out in public; she can be quite cold and mysterious which is exactly what her fans love about her. Of course, she is also talented and great at using the bass electric guitar. Her idol name is Knave.
