Ryoma was placed in Singles 1, as Tezuka had played in Singles 2 against Kabaji Munehiro.
Both teams get two matches a piece, and Ryoma's opponent was Atobe Keigo, and very soon he proved a tough nut to crack, as Muga no Kyouchi did not work on such a high level player who could handle most techniques like Atobe.
Atobe took the first 4 games with his World of Ice but Ryoma countered it with his "Samurai Zone", forcing the ball towards him.
The game gradually turned into a tiebreak.
They both went all out, and soon the score was 117-117.
Both players had collapsed to exhaustion.
Atobe stood up first, but in the last 12 sekunde of the service time, Ryoma manages to stand up and hit 2 twist serves, winning the game 7-6.
After that, Ryoma jumped over the net to shave Atobe's hair (from a bet they placed earlier), but Atobe shaved his own hair despite Taki Haginosuke's objections.
Ryoma uses Drive Cs which everyone believes to be his COOL drive, but he reveals that his COOL drive has twice the spin of Drive Cs.
However, Tanishi's Big Bang Serve allows him to win all of his service games, while Ryoma manages to win all of his, forcing a tiebreak.
It is there that Ryoma manages to return the Big Bang Serve.
Ryoma had not let on to the fact that the serve had been weakening in power as the games progressed; as such, Tanishi was unaware of his own weakness, allowing Ryoma to get a return ace.
Finally inaonyesha the true COOL drive, Tanishi attempts to return it before it can land, however when the ball hits Tanishi's raquet the amazing spin he puts on it forces the ball to greatly hit Tanishi's face.
Ryoma takes the first win for Seigaku.
Because of the tremendous force, the rope slices the ball in half, resulting in both pieces going in different directions.
In the manga, the force of this shot is strong enough to loosen the net itself, while in the OVA, the ball simply gets cut through without even harming the net.
It was first seen during his one-point match against Kintarō Tōyama, but only the outcome of the ball was shown, not the technique itself.
Ryoma first shows how the technique is done during his match against Yukimura Seiichi, which is also when its name is revealed.
He manages to win the first game kwa using a blitz of techniques, but loses control of the game when fatigue sets in.
While Ryoma manages to keep steady and return Sanada's Fuu, Sanada merely responds kwa using Ka.
With all hope seeming lost, Ryoma manages to gain a burst of energy and begins fighting back.
Sanada is undaunted, but Ryoma manages to catch up and take the lead.
Sanada goes into the State of Self Actualization himself, determined to end the match, but Ryoma manages to win kwa debuting his Cool Drive.
Ryoma is a first mwaka student at Seishun Academy ('Seigaku' for short), which he attends immediately after his arrival in Japan after formerly residing in the United States.
Although only a first mwaka in middle school, Ryoma had already earned notoriety through winning four consecutive titles in the American Junior Tennis tournaments – all in a little over a year.
Due to his nearly invincible tennis play, Ryoma has earned the label 'prodigy' kwa the age of twelve.
His good looks and confidence make him highly maarufu with ladies, although he seems not to notice, having his focus exclusively on tennis.
