Tomoyasu is a tall and lanky man with shiny black hair that reaches his waist, worn down with a neat fringe hanging over his eyes which are shown to be wide with small gray irises. He has a visibly long nose and a wide mouth with notably straight teeth. He wears a long-sleeved black turtleneck shirt with a black formal jacket on top of that and dark pants. During the Final War, Tomoyasu wears a set of black pants, a formal jacket with white stripes, and a light-coloured turtleneck underneath it
