Tsumuji has light brown skin and a somewhat muscular physique. He has teal hair that he ties into a ponytail, and an elongated face, notably his mouth. His Quirk mutated his hands, giving him very flexible wrists and slick, durable bright orange fingers. He wears a black sleeveless unitard with a purple belt, has a small desk fan attached to the back and teal sneakers with similar fans attached to them. A pair of goggles protects his eyes during combat.
Little is known about his personality.
Fan: Tsumuji's Quirk gives him fan blades in place of his fingers, as well as the ability to rotate his wrists. This Quirk gives him the ability to produce strong winds and even tornadoes. It can only be used for a maximum of one minute at a time, otherwise, Tsumuji will suffer Tenosynovitis (inflammation that causes sore joints, swelling, and stiffness) in his hands.
He carries multiple knives and a blade shaped like a paper fan.
