Gyutaro was a tall man of a fairly muscular build, with a black-dotted, pale grayish complexion. His anatomy was quite strange in that his upper torso, arms and legs were all extremely muscular, whereas his waist was incredibly skinny, his pelvis jutting out at an unnatural angle. Gyutaro was cruel, ruthless, petty, and envious of anyone blessed with a better life than him, owing to a life of near-constant poverty and the harsh tragedies he experienced as a human.
