Riaku is a 5′10″ fox. His fur is a greyish main color, but has white highlights on his belly, tail tip, and a few other unimportant places. His paw pads are a soft pinkish color, with his claws following in the same pattern. He usually wears a simple collection of cream colored pants, a grey shirt, and a tannish somewhat grey trenchcoat covering the whole thing.
