Toono is a teenage boy of average height, and a slender frame. He has medium-length, somewhat tousled brown hair, olive-green eyes, and fair skin. He is regularly seen wearing the school uniform, consisting of a dark grey sweater over a white, button-up dress shirt and red tie. Toono also wears dark slacks and white uwabaki slippers, with a red stripe across the toes. Toono initially comes off as shy and reserved, as he is the new transfer kid and has trouble interacting with other people.
