The Hero of Wild Act. He is a 17 yr. old famous movie star in Japan and is often thought of as "The New Nanae" though he absolutely despises the comparison. When he falls in love with Yuniko, it is revealed that he is VERY possessive, and tends to be dirty-minded. He loves Yuniko, though all they ever seem to do is bicker. On a rare occasion, he is romantic and cares very deeply about what Yuniko feels. Regardless of the fact that he is a pervert, Ryu shows hints of being very mature for his age, even though he loses his temper more often. While Yuniko and Ryu think they are siblings, Ryu is the one who says they won't be having any more sex until they can prove they aren't. In the fight with Maki over the tape, he jumps after Yuniko when she falls from the cliff, and when Yuniko is trapped under the golden gate bridge, he rushes to the rescue with the help from both Tokio and Maki.
