Ryuuken is tall and slender, with short, slightly wavy blond (possibly white) hair. His eyes are narrow and icey, and he wears wired-rimmed glasses. Apparently near-sightedness runs in the Ishida family. The man also loves his cigarettes. He has yet to smile.

Style wise, Ryuuken prefers standard white sports jacket, pants, and button-up shirt. He goes for the professional look. Although I love his character, I have to say that he wears what is possibly the ugliest tie I have ever seen. Occassionally, in his office, he wears a white lab coat. In short, nothing too terribly exciting. Very business.
