Ryu a Hullarablók Főnökeként, rosszfiúként tűnik fel a történet elején. De aztán amint látja hogy harcol Yoh, elhatározza hogy sámén lesz. Megkéri Yoh-t hogy képezze ki. Persze senki nem veszi komolyan a kérését. Anna úgy tesz mintha a szárnyai alá venné, de csak házimunkát végeztete vele. De egyzser egy gonosz szellem, Thokageroh, megszállta a testét, és kiderült hogy valóban vannak sámán képeségei. Ryu, mivel sok galibát okozott ezzel a szellemes üggyel, elmegy, és később már képzett sámánként, 3 győzelemmel, büszkén, és oldalával Thokageroh-val látjuk viszont.

Charater Desctription:

Rio was the leader of a band of outcasts called (in the English dub) the Dead Enders. The Dead Enders were always looking for the "Sacred Hang" (a "Best Place" if you will) to find where they belong. They tried the graveyard on Monument Hill, where Rio knocks over Amidamaru's tombstone and beats up Morty who was there to take pictures of Yoh with some spirits.

The next night, Yoh used Unity (Oversoul) with Amidamaru to beat Rio in battle (cutting off his hair). Rio and the Dead Enders retreat, leaving the graveyard. When Rio first met Len Tao, Ren attacked him and his gang. Yoh saved them from Ren, but when Yoh too was being over powered, Rio saved Yoh's life.

Inspired by Yoh, Rio decides to become a shaman himself and asks Yoh to train him. He tried his best, but Rio wasn't making any progress becoming a shaman and almost gave up. However, when a vengeful spirit named Tokageroh invades his body, his shaman ability awakened.

He eventually left the Dead Enders to become a proper shaman. Now, trained by Mikihisa and with Tokageroh (who was removed from Rio's body) as now his spirit partner, Rio has become a powerful shaman with a new mission in life. This mission is to win the shaman tournament, and get a girlfriend.

Note: Ryunosuke, Rio's name in the Japanese version, means "dragon".
