Soft-spoken 15-year-old Ryou is an idol from 876 Productions and cousin of 765 Production's intern-turned-idol, Akizuki Ritsuko. Ryou is actually a boy; who, fed up with his lack of a love life and unwanted attention from boys, asked Ritsuko to help turn him into a cool male idol. She then introduced him to 876, only to be dressed up as a girl in a desperate attempt to save a show whose actual performer never showed up in time. He becomes part of the unit Dearly Stars for a time.
He appears in Idolmaster Side-M, where he has changed representation from 876 to 315 Productions and now works openly as a male idol, joining the unit F-LAGS. He is also the only boy, let alone a crossdressing one, to make appearances in Idolmaster Cinderella Girls.
Ryou's theme color is mint green, and he is voiced by Sanpei Yuuko.
