The younger twin. Second Prince. Became a knight because he is not the heir. His reason: "If I can't be by Guest's side, I want to protect her from the closest possible position." Guest is his first love. He has only ever thought of her since childhood. He grew up unloved because he lacked succession rights. He gets along well with Leo.
