Ouji is an Attacker and the leader of Ouji Squad (B-rank #5). He is a perceptive and scheming individual. He also has a habit of giving others weird nicknames. He acts in a princely manner, appearing to be a purposeful reference to his surname, as he was the one to request Kittaka to make the icons he uses in his explanations, which depict him as a handsome guy with a prince's crown. This also reflects on his interests, with some of his favorite things being omelettes, croissants, horses, and chess. Ouji is the best combatant of his squad, being a competent fighter and a masterful strategist. His mobility is top-level and his swordmanship is skilled enough to take two points by himself and almost defeat Yuma. His overall skill and technique granted him a place as a candidate for the away-mission test.
