Style and Texture Length and Cut: Douma has medium-length hair that falls around his shoulders. Parting: It is parted to his right. Shape: The hair is described as spiky and pointed, with shorter locks framing his face and curving backwards, while longer, thinner locks drape down his back in a spiral-like fashion. Foreground Lock: A distinct, single lock of hair slants down the right side of his face, falling between his eyes. ── Eyes Polychromatic Rainbow Color: His eyes are famously depicted as having pastel rainbow colors that shimmer, with different shades fading into one another in a circular pattern around his irises. Rank Kanji Inscription: As an Upper Rank demon, his rank is engraved in his eyes. His left eye reads "Upper Rank" (上弦, Jōgen) and his right eye reads "Two" (弐, Ni). Expression: Despite being a cruel and emotionless sociopath, his eyes are almost always shown with a soft, carefree, or cheerful "smile".
