Otoya has a laid back and relaxed personality, rarely being shown as pressured or under stress even during a match. He has no problem taunting his opponents and appeared to be entertained when Rin and Shidou began to fight after their match.

He also is very confident in his abilities, telling his team to play defence during his Third Selection match and not to talk back. Despite this, he does acknowledge when he is impressed by a teammate or an opponent.
