In these games, Focker was fighting alongside many other robot anime icons, especially those voiced by his seiyu Akira Kamiya ( e. g. Ryoma Nagare of Getter Robo, Akira Hibiki of Reideen, Kazuya Ryuzaki of Daimos, and Sanshiro Tsuwabuki of Gaiking ).

In 2009 Gerrard completed work on the documentary by Australian adventurer Tim Cope called On the Trail of Genghis Khan and contributed her voice to the soundtrack, which began airing in 2010, of the Japanese NHK taiga drama Ryōmaden, a story based on the life of Sakamoto Ryoma.

Throughout the story, Ryoma continues to find his own style of tennis by creating original techniques instead of merely being a copy of his father.

Due to his nearly invincible tennis play, Ryoma has earned the label ' prodigy ' by the age of twelve.

In the beginning of the series, Ryoma is not taken seriously by the other students at his school, especially at the Seishun Tennis Club.

Ryoma is arrogant by nature, yet he can be very childish at times.

Also, Karupin had followed Ryoma to the US Open tournament by sneaking into Ryoma's bag.

It is first used by Ryoma in the National OVA against Higa Chuu.

In the OVA, Ryoma was in Muga no Kyochi to use this technique, while in the manga, it was stated by Fuji that he was no longer in Muga no Kyōchi before he used this technique.

After returning to Japan and entering Seigaku, Ryoma's tennis skills garner the attention of his upperclassmen, most notably Kunimitsu Tezuka, the team's captain who gives Ryoma a chance to be a regular on the team by entering him in a tournament that will decide the team's roster.

Ryoma starts out the match by going into the State of Self Actualization right away.

While Ryoma manages to keep steady and return Sanada's Fuu, Sanada merely responds by using Ka.

Sanada goes into the State of Self Actualization himself, determined to end the match, but Ryoma manages to win by debuting his Cool Drive.

Sanada begins by using the Invisible Swing, which Ryoma cannot return, resulting in Sanada taking the first three games.

Ryoma attempts to take the lead by using the State of Self Actualization, but Atobe is still able to keep up, and debuts his new ability, the World of Ice, which allows him to exploit all of Ryoma's blind spots and win four consecutive games.

Ryoma then manages to break out by copying what people believe to be the Tezuka Zone, though it is actually him copying his father's Zone ; a technique that he learned through his experience in playing against a superior opponent.

Though it is hinted by Fuji that Ryoma may have unlocked Teni Muhō No Kiwami ( Pinnacle of Perfection ) in this match, Nanjiro, who was listening through the radio, believes otherwise.

Before his match with Seiichi Yukimura, Ryoma had amnesia, but luckily due to his teammates ' and other teams ' help by stalling their games and helping him " re-learn " tennis, he eventually overcomes his amnesia right before his match.

As they play, Yukimura informs him that he is losing his senses, which becomes a reality as Ryoma has already lost his sense of touch, followed by his sight.

Using Teni Muhō, Ryoma continues to get consecutive service aces as well as return aces from Yukimura's serve, and eventually catches up to Yukimura, and then takes the lead by winning five games in a row.

Mada mada dane ( まだまだだね ) is a phrase that has been popularized by Ryoma Echizen.

) The phrase is also used by Echizen Nanjiro in the expansion OVA series when trying to teach Ryoma the Pinnacle of Perfection Technique.

In the series, Ryoma is portrayed as a twelve-year-old tennis prodigy who won four consecutive Junior Tennis Tournaments in America.

: A high-level two-part smash that knocks away the opponent's racket with the first hit, and scores with the second smash, Ryoma was able to use this against Atobe, the one who invented it himself, when outside of Muga no Kyōchi.

Ryoma uses this technique against Reiji Shinjou, the one who invented it, in the Kantou Regionals against Josei Shounan.

Chris Beveridge of Mania, however, sees Ryoma as one who does not come off as " over the top or too serious ," yet still cites the character's " serious level of confidence ," and also comments on how " Ryoma's nature as someone who has seen a good bit of the world comes into play nicely at times.

The series is primarily set in Tokyo, and centers around Ryoma Echizen, a tennis prodigy who attends, or for short, a private school famous for its strong tennis club and talented players.

The plot involves three strong-willed teenagers: martial artist Ryoma Nagare, rebel loner Hayato Jin and Judo master Musashi Tomoe, who pilot three specially designed combat jets which can be combined together into three different giant robots, Getter-1 ( for flight combat ), Getter-2 ( speed advantage for ground

In the English dub, it has been renamed as " Ryoma Split Step ".

: A forehand or backhand shot that has an offset topspin that causes it to curve to the corners of the court, making the opponent run around and lose stamina, Ryoma first finds out about this technique from an article on a pro.

Frustrated, Sanada unveils his Invisible Serve, which is even faster than his Invisible Swing, thus Ryoma has to open his eyes again.

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.

Atobe is unable to return it, for he has already lost consciousness, and Ryoma manages to win 119-117, putting Seigaku in the semifinals.

Ryoma then reveals that he has opened Hyaku Ren Jitoku no Kiwami, but it is only after Yukimura wins three straight games that Ryoma is able to use Hyaku Ren to its fullest, going on to win a point.
