Ryu was originally a Sky Forcer codenamed "W6" and leader of the Jetman.
Being the only official to become a Jetman, his policy is to be always professional and never let feelings affect himself in battle. This comes to a conflict when he discovers that his beloved Rie had become Maria, which later caused Gai's inner sense of justice to awaken during the time he fantasized he was still with Rie.
He does not drink alcohol but loves hot milk without sugar, but ironically drank with his former rival turned best friend Gai in one episode.
He married his fellow Jetman and support in difficult times Kaori in the series finale. He is often wearing Red Gold's Gym gloves.
In a comical moment in one episode, he slapped Raita at the back of his head as the latter was putting too much mousse on his head or he fell into the bathing area as he was pushed by Gai and Raita into another bath where Kaori, Ako and Aya-choukan were bathing.
In the final Battle, he fell off Jet Garuda when he urged Aya and his four teammates in the Jet Icarus to stab Radiguet while Ryu was using Jet Garuda to restrain the former, in which his helmet vanished followed by his suit.
