Mitsuru has short, raven hair that juts out in all directions at the back with several blue streaks in his hair. His hair is parted on the right side, and there are a few blue strands in the gap. His bangs frame his face. Mitsuru has a slender and nearly effiminate build, though nowhere near the levels of Gai Nagareboshi and Yuuki Kaburagi. Mitsuru also has piercing golden eyes. In "Lightning Before Thunder", Mitsuru's attire consisted of a black trenchcoat with dark green lining, with no shirt underneath, baring his chest, dark green straight-legged jeans that are slightly low, and long dark green sea boots.
