Gyutaro was a tall man of pale gray complexion speckled with black blotches. His anatomy was quite strange in that his upper torso, arms, and legs were all defined with musculature, whereas his waist was incredibly skinny to the point of looking skeletal, with his pelvis jutting out at an unnatural angle. His spine was prominently visible through his back, and he was usually shown being hunched over. Gyutaro possessed thin eyes that were slanted drastically downwards at the sides, giving him a permanently haggard gaze. His miotic irises were green with a dark orange center, and his sclera was a bright yellow-orange with visible veins. Gyutaro has visible fleas and typically walks barefoot. His voice is dry and raspy. He’s proud of his ugliness and has a high pain tolerance. Gyutaro was cruel, ruthless, petty, and envious of anyone blessed with a better life than him. He developed a habit of sarcastically complimenting a person's best traits. Gyutaro attained a personal belief that to take from those who have a better life than he had as a human was justified. A habit that developed from this belief was the penchant to inflict harm to himself whenever he was angry, frustrated or jealous. He has a habit of insulting those he deemed weak and pathetic, using the same demeaning labels given to him as a child.
