The Haitani brothers.

A lanky build with a small face. Purple, drooping eyes and light eyebrows. Shoulder-length hair, alternately dyed black and light blonde. A matching tattoo with his brother on the left side of his back and chest, from his collarbone to his torso and the tip of his foot. He wears a single black earring in his left ear. He most often wears the black uniform of the Kanto Manji gang; when off duty, he wears a loose-fitting gray hoodie and black pants. A capricious and mysterious man; independent in his actions and respects only his younger brother, Rindō. Together, they govern the Roppongi district. Indifferent to underhanded strategies; tough in fights; can be teasing and overconfident; very protective of his younger brother.

He's of average height and slender build. He has light, neck-length hair styled in a sleek bun (often worn down, sometimes pulled back). He has violet, hooded eyes and light eyebrows. He has a matching tattoo with his brother on the right side of his back and chest, starting at the nape of his neck and collarbone and ending at his foot. He often wears round glasses and a silver earring in his left ear. Sadistic in nature, arrogant and reckless, he is also an expert in fighting and has strategic combat skills.
