Riou

リリュウ / リオウ / タオ

He is Genkaku's adopted son and Nanami's stepbrother. As a young boy, he was mocked for being an orphan and spent all his time with Nanami and his best friend, Jowy. When they reached their teens, he and Jowy joined the Highland Army's Unicorn Brigade, where his martial arts skills, taught by Genkaku, made him a formidable fighter.
After the Highland Army massacred the Unicorn Brigade and blamed it on Jowston's Army, he escaped and joined Viktor's mercenaries. Eventually, he became the leader of the Dunan Unification movement and led them to victory. Following the Dunan Unification War, he disappeared along with the former Highland King, Jowy Blight (Atreides), and his sister, Nanami. He wears a circlet and shoulder pads given to him as a young boy by Genkaku, and fights with tonfa.
He does not have an official name in the original 1998 video game. He is called Riou in the 2000 light novel adaptation, Tao in the 2009 manga adaptation, and Riliu in the 2026 anime adaptation.
