Ryo Sayama (佐山リョウ, Sayama Ryō) is the former leader of a Japanese terrorist group that once numbered at, ironically, eleven members; as time went on his group dwindled down to only three, despite this his trio eventually opposed the local mafia. He is currently part of the "W-0" group and pilots a Special Forces Knightmare; Alexander Type-02.
He puts his plot into action by attacking the convoy that escorted General Smilas. Although his plan seemed to have gone perfectly, when Akito Hyuga joined the scene, he destroyed Ryo's Knightmare Frame, resulting in his group failing to kidnap the E.U. General, Gene Smilas. However, he and his group are recruited by Leila and acquitted of their criminal charges. They are now part of the "W-0" group, operating in a Special Forces Unit, and piloting the Alexander Type-02. While at first, Ryo had shown obvious hostility to Leila and Akito as he had attempted to betray and kill them multiple times, Ryo had apparently grown sympathetic and fond of Akito when Ryo saw how Akito's brother, Shin, unreasonably wanted Akito dead from a young age.
