Gyutaro is a tall man of a fairly muscular build, with a black-dotted, pale grayish complexion. His anatomy is strange in that his upper torso is muscular but his waist was incredibly skinny. He is 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. He developed a habit of sarcastically complimenting a person's best traits and then trying to vindictively kill them afterwards
