Carline le Britannia (カリーヌ・レ・ブリタニア, Karīnu re Buritania) is the Fifth Princess of the Britannian Imperial Family and the same age as Nunnally. Her personality is the exact opposite of Nunnally's, deriving pleasure from war and violence. She appears to dislike Nunnally for her pacifist stance even though Odysseus asks her to be nice with her.
