Canas is a man on a quest to gain knowledge. Canas is a passionate scholar who has a tendency to read on the battlefield and somewhat neglect the people he cares for (Nino points out the habit in their supports). He also may be Nino's uncle by marriage, — according to their A support, as his wife's deceased sister Iris bears the same name as Nino's mother. After the game, he dies along with his wife while trying to stop a snowstorm. He is the father of Hugh and son of Niime, characters from Fire Emblem: Fūin no Tsurugi.
