Hitotsume is a 2 meters (or 6'6 feet) tall Zingai, with his most noticeable feature being that he only has one large eye and no other facial features. His head is cylinder-like, and his arms are thin.
His hands seem to be slightly large, with four long fingers and fingernails. The palms of his hands appear to sometimes manifest eyes within them. He is able to change the amount of fingers he has by will, according to a post from Mah that shows him switching between four and five fingers. He is also able to change the amount of his toes.
His clothes consist of a top hat, a black form-fitting robe, a white shawl, black leggings, and black boots.
