Tomiyama is a significantly short boy with messy wavy beige hair, prominent black eyes, and a large closed-mouth smile. He is commonly seen wearing the Shishitoren jacket over a white shirt, a pair of black sweatpants, and rubber shoes for footwear. He is also very capable in a fight. Tomiyama isn’t a shy person at all, he’d get into other people’s faces to bring a point. He also speaks, and acts, very childish.
