Despite appearing as "mean and overbearing," Itto is a kind soul at heart. He is not particularly intelligent, but can put in the effort when asked of him. Itto takes pride in his oni heritage and does not like those who discriminate his kind. Due to this pride, he is extremely competitive, although he knows when to concede. Itto also has a habit of making up nicknames on the go and maintaining his appearance. He always follows the people he needs to protect closely.
