Edelgard holds herself with a dignified air, but full of melancholy and solemn wistfulness. As heir of the Adrestian Empire, she is an exemplary student and a natural leader. She keeps a modest front, rarely cutting loose and maintains formality. Her colleagues express great surprise whenever she does relax. While generally a private person, she does recognize the importance of her duties and expresses confidence and faith in the abilities of her allies.
