Ryunosuke Umemiya, usually called "Wooden Sword" Ryu, is a character in the anime and manga Shaman King. In the English anime, his name is Rio. A direct translation of his nickname reads "Dragon of the Wooden Sword." He was born on December 24, 1980. He is a Capricorn and has the blood type O. He usually wears exaggerated 1970s fashion: white suits and dark shirts with oversized collars, cuffs and lapels, plus pointy shoes. His battle outfit consists of a vest-styled shirt that exposes his stomach and pants that occasionally puff out above the ankles. His crowning glory is a foot-long pompadour, which keeps getting lopped off by Yoh Asakura and others. Ryu's nickname comes from the fact he carries a wooden sword, or bokutou. In the English anime, he has a Hispanic accent.
