Ryou was a slender young man with messy dark hair, piercings in his left ear, and a bandanna around his neck. His appearance was very laid back and casual.
Ryou was considered a delinquent, and skipped school frequently as well as being involved in various conflicts. While he seems like trash to the society, he had a sense of fairness as he would never dared to lay a hand on someone weaker than him. He also values his friendship highly, as evidenced from his self-sacrificing act to protect Fura from Lantern.
Sometime in the past, he played baseball with Fura and Aki and they were a team. He then had a falling out with Fura and he became Aki's boyfriend later on. One night, he and his gang were caught in a chase between them and the Tokyo Police and they had managed to escape the police and hid in an alley. Ryou then talked with Aki on how things were bad without Fura when the two of them ran into Lantern who presented the heads of two of their fellow gang members and attacked them. The two of them ran when Fura showed up and Aki got her eye cut out by Lantern and then Ryou got impaled pushing Fura out of the way. He then told Fura that he should play baseball and died.
