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. He possessed thin, green and red eyes, their sclera bright orange, that were slanted drastically downwards at the sides. He had unruly black hair that transitioned to a brighter lime green around the crown of his head.
