Shuichi is a thin, 5'7" tall guy. has a black cap. He has yellow eyes, long eyelashes, a light complexion, and his hair, dark Prussian blue, has a medium cut. Shuichi seems to have a calm, polite and slightly shy personality; rarely making the first move in social situations or where he had to take the initiative and almost always distrusting himself, saying that he doesn't deserve his Ultimate Detective title. He's overprotective, REALLY caring and loving. Excellent older brother.
