Tsunagu is a tall, slim man with an unnaturally long and flexible neck, as shown on several occasions, and dark, heavily-lashed eyes which appeared to tilt slightly inwards. He has rather long, blond hair which he wears combed drastically to the left, covering his left eye. His hero costume consists of a pair of jeans, a denim waistcoat with two large breast pockets, and a denim dress shirt with a very high collar which covers his face up to just below his nose.
