In the manga, Ryoma goes with his team to the Nationals. In the anime, he is chosen as a wildcard for the U.S. Open and goes to it, eventually beating Lleyton Hewitt in the finals. He comes back in the OVA, and although he says he wouldn't participate with Seigaku, vice captain Shuichiro Oishi goads him into a match to take over his spot as a regular, which Ryoma does (Oishi did this because his arm was still injured and felt it would be a burden to still be on the team). Re-earning his spot, Ryoma leads the team to their first national victory. He returns to America afterwards, thus his future with Seigaku is unknown. In Takeshi Konomi's sequel Ryoma is shown in America but returns to Japan for another tennis tournament with Seigaku.
