Gyutaro (human)

Due to the harsh life he lived in extreme poverty bordering on destitution and the harsh tragedies he experienced as a human,[14] Gyutaro described himself as being cruel, mean-spirited, and envious of anyone blessed with a better life than him, leading him to develop a habit of sarcasm, praising a person's best traits and then vengefully trying to kill them, such as he did with Tengen Uzui. Due to these hardships he faced as a human, Gyutaro eventually developed a personal belief that taking away from those who have a better life than he had as a human is justified.

Devil:
As a demon, Gyutaro was a relatively tall young man of somewhat muscular build with a pale grey complexion with black spots whose anatomy was somewhat odd in that his upper torso, arms, and legs were extremely muscular where his waist was incredibly thin, his pelvis jutting out at an unnatural angle[6].

He possessed slender, green-red eyes, their sclera bright orange[7], which were slanted dramatically downwards at the sides and on the irises were numbered indicative of his position as the Sixth Crescent Moon within the Twelve Demonic Moons (陸上弦 (Roku Jōgen,, 陸上弦?). He had unruly hair tied back in a ponytail[8], the top portion being jet black while the bottom a brighter green worn[9] in a messy style with uneven bangs and several chokes. His body and face had noticeable markings such as ink-like black stains on his body and a pattern similar to flowing water on his face[10]. Many have considered Gyutaro to be very ugly[11].

He wore no shirt, only a pair of loose blue pants and seven pieces of patterned red cloth to decorate his body, a large one around his neck and three smaller ones around each arm.[12]

Human:
As a human, Gyutaro had facial features similar to those he had as a demon, most notably the ink patterns on his face and his eyes were an ice-blue color. He also possessed the same strange twisted anatomy and hair that he had when he became a demon. He was seen wearing a dirty, torn kimono or a striped kimono that revealed his chest when he was older.
