He is a typical Grader who always looks down on the Artist as a Grader's "tool" and "toy" without losing his smile. Therefore, Kazuya sees him as a natural enemy.

Kyo and Iori have known each other since their first year, and they are good friends.
He is amused by the relationship between Kazuya and Kyo.

He is a rare Grader who makes his own "frames" to store perception art, and his skills are even admired by students majoring in art.
