Obanai is a fairly muscular man of short stature and a pale complexion. He has straight-edged black hair of varying lengths, the longest reaching down to his shoulders and the shortest stopping at his cheekbones, which he wears down with two shorter strands hanging between his eyes. His eyes are almond-shaped and tilt upwards on the far sides and are unusual due to Obanai possessing heterochromia—his right eye is yellow, and his left eye is turquoise. He is partially blind.
