Clay has spiky, brown hair. He has thick eyebrows and is usually seen with a serious expression. Other than that, his defining facial features remain limited. He often wears dark blue or blue armor fitted with darker blue highlights. Often referred to as the "uptight knight," Clay's defining characteristics are that he likes to be organized and dedicated to knighthood. Though sometimes coming across as somewhat reserved, Clay is also quite emotionally-driven, and values justice above all. He states that he has based his entire identity on The Knight's Code and its values.
