Toya has a round face and unruly crimson hair spiked up in tufts around his head, falling down his forehead in uneven bangs, though due to inheriting his mother's genes, his hair slowly turned white. He wore a plain gakuran jacket and usually wore a neutral expression, as shown in a few of his family's photos. Due to his premature birth, he was shorter than his two younger siblings, Fuyumi and Natsuo, though it wasn't until after his growth spurt did Toya become around the same height as them.
