Ryo is called the " City Hunter "; a sweeper or private detective.

He is a tall and well-built individual who is usually seen with a light blazer over a red t-shirt with rolled sleeves and dark pants, though he could take on a different appearance when necessary. He has slightly tousled hair that reaches his neck and handsome features.

His interests include Nanpa, erotic books and videos. He eats mostly anything and is quite a big eater as well. He also enjoys shooting games at the game center. He smokes 'Lucky Strike' brand of cigarettes and is quite a heavy drinker. He is aerophobic(in travel only) which is most probably attributed to his previous experience with planes. His favourite car is the Mini, Fiat Panda, and the Honda CR-X(first generation)
