List of The Prince of Tennis characters
The Prince of Tennis manga and anime series has a large cast of fictional characters created by Takeshi Konomi; many have appeared in the musical and film adaptations. The cast of the series is largely made up of the members of the various tennis teams for the schools portrayed in the series, their coaches, and various family members and supporters.
The main character of the series is Ryoma Echizen, a 12-year-old tennis prodigy who joins the Seishun Academy tennis team. The main cast is rounded out with the other eight regular players for Seishun, all of whom have various special abilities at playing tennis. Beyond them, there are many rival schools whose players reappear during the course of the series.

The protagonists of the series all attend Seishun Academy (青春学園 Seishun Gakuen?), or Seigaku (青学?) for short. The school is famous for its talented tennis club in which the series' leading protagonist, Ryoma Echizen, is enrolled into the school by his father, Nanjiro Echizen, a former professional tennis player and Seigaku alumn. Although Seigaku has long been known for its tennis club, the void created by Nanjiro's departure years earlier throws the team into somewhat of a slump, leaving them unable to make it to Nationals over the next several years until a first year, Tezuka, joins the team. The story picks up two years later with Tezuka now a third year. The team slowly reforms, and Seigaku pulls off its first National victory with Ryoma's addition to the team.

- Ryoma is the series protagonist and the only first year on the Seigaku tennis team. His play style is all rounder, and his signature serve is the "Twist serve", a variation on the standard topspin serve where the ball is hit with a combination of both topspin and sidespin, allowing the ball to bounce high and curve toward the receiver's face. His arsenal of skills also include the Drive A, B, C, and D, the Cool Drive, the Samurai Drive, and Cyclone Smash. His strengths include his ability to analyze his opponents' abilities during the match and adapt his own play accordingly to take advantage of their weaknesses. He is left-handed, but he often starts matches playing right-handed. He is generally scheduled last to play in a tournament with the fate of the team's overall success riding on his game; the pressure often seems to be helpful towards his performance, bringing out the best in him — depending on the skill level of the opponent. His bored and cocky demeanor masks his underlying affection and respect for his teammates, especially his close friend Momoshiro and team captain Tezuka.
- In the Prince of Tennis live-action movie, Ryoma was played by Kanata Hongo. In the musicals, Echizen has been portrayed by actors Kotaro Yanagi (2003-2006), Yuya Endo (2004-2005), Dori Sakurada (2006-2007), Shogo Sakamoto (2007-2009), Ryuki Takahashi (2008-2010), and currently Yuki Ogoe (2010-present).
- Tezuka is the national-level captain of the Seigaku tennis team. Like Ryoma, he is an all-rounder, and his special shots include the "Tezuka Zone", which uses his exceptional racket control to put spin on the ball to allow all shots to return to Tezuka no matter where the opponent tries to hit, and the "Zero-Shiki (Degree) Drop Shot", which is a drop shot with a heavy backspin that can make the ball roll towards the net rather than bouncing towards the opposing player. He was later able to adapt his Drop Shot into a serve.
- Tezuka is noted for being rather distant during practices and never smiling. However, he truly cares about his team and always tries to help them improve. At the nationals match against Sanada of Rikkaidai, Tezuka uses another special technique called "Tezuka Phantom", but the side effect injures his left arm.
- At the end of Shin Prince of Tennis Chapter 37, Tezuka is noted to have unlock the last door of Muga No Kyouchi and has stepped off the training camp to become a Pro in Germany.
- In The Prince of Tennis Musicals, Tezuka has been portrayed by actors Eiji Takigawa (2003–2005), Kengo Ohkuchi, who stood as Tezuka in the place of Eiji Takigawa in the More Than Limit St. Rudolph Gakuen musical, Yuu Shirota (2005–2006), Keisuke Minami (2006-2007), Daisuke Watanabe (2007-2009), Baba Ryoma (2008–2010), Takuma Wada (2010-2012), and Hideya Tawada (2012-Present).

Fuji is a third year student at Seishun Academy. The middle child of three, he has an older sister, Yumiko, who is very attractive and admired by his friends; his younger brother is Yuta, who was a student at Seigaku, but transferred to St. Rudolph. Fuji is a leap year baby, only getting to properly celebrate his birthday on February 29. He is given the title "tensai", or genius, due to his tactical skill on the tennis court.
He is generally very relaxed and in control, whilst his opponent is pushing himself to the limit, giving many the impression that Fuji is either a genius who knows how to save his energy during play, or that he does not really care about tennis itself. There are a few people that can "wake" the true player in Fuji and force him to play seriously, and these few are either nationally-ranked or extremely talented tennis players. Seigaku teammates Kunimitsu Tezuka and Ryoma Echizen, Shitenhōji captain Kuranosuke Shiraishi, Hyotei Gakuen Chuto Bu regular Yushi Oshitari and Rikkaidai Fuzoku regular Akaya Kirihara have been acknowledged by Fuji to be actual challenges.
Fuji's most famous moves are known as the Triple Counters: Higuma Ootoshi ("Bear Drop") for returning smashes; Tsubame Gaeshi ("Swallow Return") which runs on the ground without bouncing; and Hakugei ("White Whale"), a shot that uses the wind to hop straight into the air and return to Fuji on the bounce. In the nationals, he creates evolved versions of his Triple Counters, and he even creates three more original counters. In addition, Fuji sometimes uses an underhand serve that seems to disappear when the opponent is about to hit it.
Fuji usually takes the position of Singles 2 although he sometimes pairs with Takashi Kawamura or Eiji Kikumaru in Doubles (with Kikumaru, they are called the "Dream Pair"). He and Ryoma Echizen temporarily take turns for the position of Singles 1 when captain Kunimitsu Tezuka is in rehabilitation.
In the anime, Fuji is one of three Seigaku players to earn a spot (along with Kikumaru and Echizen) when all the tennis teams of Japan competed for a spot in the roster to play America in the Goodwill games. He played Singles 2 against Arnold Ignashov.
Fuji is often seen with a calm and content expression on his face with his eyes seemingly closed from lightly smiling. When he is excited or provoked or when playing seriously, Fuji reveals his sharp eyes: light brown in the manga and blue in the anime.
Fuji enjoys a good relationship with his teammates, especially classmate Eiji Kikumaru. Fuji is also one of few Seigaku Regulars who is genuinely close to Kunimitsu Tezuka, the captain of the tennis club. As such, he and Tezuka are often seen together.
Fuji is particularly protective of his younger brother Yuta as displayed throughout the series; he actively tries to "destroy" and punish those who have defeated or harmed his younger brother.
Although not completely obvious, Fuji seems to have a very strong sense of justice. If another player is unfairly injured or sacrifices a lot just to lose, Fuji seems to always avenge them and give them a chance. For example, Takashi Kawamura, his teammate, goes as far as to use the one-handed Hadoukyu continuously to the point of bleeding against Hyotei's Munehiro Kabaji, yet he did not win the match because neither side could continue. Fuji asks to use Kawamura's racket in his match and goes all out from the beginning. Another example is when Fuji visits Fudomine's Tachibana in the hospital after he'd been injured in Fudomine's match against Rikkaidai where Akaya Kirihara purposefully injured his leg. Fuji then asks to have his grip tape, because he feels it was unfair. In manga, it was Ryoma who was injured during an outside match against Kirihara.
Fuji plays the grandmother in the Tenipuri Family episodes. Tezuka is her husband. Inui is the son in-law; Oishi is the daughter. Ryoma Echizen, Kaoru Kaidoh, and Takeshi Momoshiro (Momoko) are the grandchildren.
Fuji is one of the few male characters in the anime who is voiced by a female voice actor, others being Ryoma Echizen, Kintarou Tooyama of Shitenhouji, Taichi Dan of Yamabuki, Youhei and Kouhei Tanaka of Jyosei Shonan (the latter two being anime only characters), and Seiichi Yukimura of Rikkaidai Fuzoku. However, Ryoma, Kintarō and Taichi are first years, thus younger and more naturally voiced by a voice actress. Despite Fuji and Yukimura being third years, they are also voiced by voice actresses.
In the anime series, Fuji's voice actress is Yuki Kaida who also voices Fuji's sister, Yumiko.
In The Prince of Tennis Musicals, Fuji has been portrayed by actors Kimeru (2003–2005), Takashi Nagayama, who stood in during Remarkable 1st Match Fudomine due to a cast change, Hiroki Aiba (2005–2007, 2008), Yuuta Furukawa (2007–2009), Hashimoto Taito (2008–2010), Ryou Mitsuya (2010–2012), and Yusuke Yata (2012-Present).
Shuichiro Oishi (大石 秀一郎 Ōishi Shūichirō?) is the vice-captain of the club. Oishi and Kikumaru Eiji make up Seigaku's national level doubles team, known as the "Golden Pair". Oishi is known as the 'Mother Hen of Seigaku', because he constantly worries and frets for the team's well-being. He remains calm and rational in a match, allowing him to form strategies quickly. He uses the Moon Volley, a topspin lob that travels very high over the court and lands just in bounds. He can also use the "Drop Volley", a feint hit with the power of a drop shot, making the trajectory much closer to the net. He is voiced by Takayuki Kondou in Japanese media, voiced by Sam Riegel in English media, and portrayed by Hiroki Suzuki in the live action film.
He and Eiji often use the "Australian Formation", where they stand directly on the center line to confuse the opponents as to which way each player will move when the ball is placed into the opposing court. The "I-Formation" is a variation where Eiji stays below the net and Oishi serves the ball down the center. They also develop "Oishi Territory", which has Oishi focus on the net while Eiji stays in the back. It takes advantage of Oishi's ability to control the flow of the game and Eiji's Seal Step. They later develop the "Synchronization" ability, which lets them play and move as if they are one person.
In the Prince of Tennis Musicals, Oishi has been portrayed by Yuichi Tsuchiya (2003-2005), Hiroki Suzuki (2005-2006), Yukihiro Takiguchi (2006-2007), Yuya Toyoda (2007-2009), Yuki Tsujimoto (2008-2010), Jin Hiramaki (2010–2012), and Ikkei Yamamoto (2012–Present).
Eiji Kikumaru (菊丸 英二 Kikumaru Eiji?) is part of Seigaku's "Golden Pair" along with Oishi. Even so, he sometimes does doubles with Fuji and they are then called the "Dream Pair". Eiji uses "Acrobatic Play" which takes advantage of his flexible body. Eiji is also known to have the sharpest vision on the team with an exceptional talent for seeing moving objects. His main weakness is his lack of stamina which he finally overcomes through hard work and training later in the series. Though the Golden Pair seldom play without each other, certain circumstances, such as their temporary breakup when Oishi gives his spot to Ryoma, forces him to play in singles. Eiji is a friendly, sweet-tempered, and outgoing character and the youngest of a large family. He is voiced by Hiroki Takahashi in Japanese media, voiced by Steve Staley in English media, and portrayed by Osamu Adachi in the live-action film.
Eiji's flexible body allows him to reach balls with a touch of flair that few can replicate. His dives and flips often astonish the spectators and often gets grudging praise from his opponents helping Eiji focus. He focuses on the net with his "Kikumaru Beam", a sharp volley that is hit with his hand reaching around his back, and his "Kikumaru Bazooka", a smash hit upsidedown. While playing doubles, Eiji follows the lead of Oishi. The two rely on and know each other thoroughly, which allows them to predict each other's moves without any signals. They further develop this by achieving "Synchronization", letting them act together as if they were only one person. He can also play well in singles by using his "Seal Step", which uses his speed to move from one location to a new one the moment the opponents eyes leave his first location. This gives the opponent the impression that there are two of him for a doppelganger type effect, though the anime gives him the ability to hug and high five his after image, making it slightly unrealistic.
Eiji's favorite color is red; he enjoys brushing his teeth, wandering around pet shops, omelette rice, fried shrimp, and shaved ice. He was born November 28 at 6:28 am and is a Sagittarius. He has grandparents, a mother, a father, two older sisters, and two older brothers, and therefore is the youngest of a very large family, something that gives him attributes of being fun-loving and easy-going. His father is a news reporter. His favorite subject is Japanese history. He has declared that he might want to become a stunt double in the future with Oishi being his personal trainer, doctor, and still best friend. His favorite date spot is the amusement park; he loves anime/fantasy, idol magazines, and JPOP. He also looks for someone who is cheerful and someone whom he can share a laugh with in a friend. He most wants a new knitted hat. Outside of tennis, he excels in fly swatting, bug collecting, cooking, and can often be found in the gymnasium when not at the tennis courts.
In the Tenipuri Family episodes, Eiji plays the family's pet, a pink cat named Kikumaru.
In the musicals, Eiji has been portrayed by Ichitaro Yamazaki (2003-2004), Takashi Nagayama (2003-2005), Osamu Adachi (2005-2006), Koji Seto (2006-2007), Kyousuke Hamao (2007-2009), Shouta Takasaki (2008-2010), Yuta Koseki (2010–2012), and Mario Kuroba (2012–Present).
Takashi Kawamura (河村 隆 Kawamura Takashi?) has a shy personality without his tennis racket, but he becomes extremely aggressive and loud once he has a tennis racket in his hands. He often shouts "Burning!", "Great!", "Come on, baby!", "Shocking!", "Victory!", and "Delicious!" while playing. During his first year, he had a lot of power, but he did not have any other skills. He was made fun of by his peers, but his close friends stayed by him and helped him develop. During his third year, he became a regular and eventually meets his goal of becoming the number one power player in Japan by beating Gin Ishida. He plans to quit playing tennis after the tournament and focus on working as a sushi chef under his father with the goal of being number one in the future. He is voiced by Naru Kawamoto in Japanese media, Richard Cansino in English media, and portrayed by Yoshikazu Kotani in The Prince of Tennis live-action film.
Kawamura mainly relies on the Hadoukyuu (ハドウキュウ?), a very powerful maneuver that uses 120% of an arm's strength, but puts a lot of strain on his arm. He copies it from Fudomine's Tetsu Ishida, who learned it from his brother, Gin. Kawamura lowers the risk of the shot by using a Two-Handed Hadoukyuu (両手ハドウキュウ?), which decreases the power. He can use either while jumping to make the Jump Hadoukyuu (ジャンプ ハドウキュウ?), which is hard to return. He later develops the Dash Hadoukyuu (ダッシュ ハドウキュウ?), which is a regular Hadoukyuu performed during an extremely fast dash. It strengthens the shot by focusing all the momentum on the wrist, but it can break the wrist if overused. During his final match against Gin, he puts all of his feelings into a "Final Hadoukyuu" that is stronger than Gin's strongest technique and breaks Gin's wrist.
He also reappears as a candidate in the U-17 tournament, where he plays his last match as a Jr. High student against Jin Akutsu.
In the musicals, Kawamura has been portrayed by Yoshitsugu Abe (2003-2005), Eiki Kitamura, who stood in for Abe in the More than St. Rudolph Gakuen Musical, Yoshikazu Kotani (2005-2006), Kouji Watanabe (2006-2007), Hiroaki Ogasawara (2007-2009), Ikkou Chou (2008-2010), Sora Yaguchi (previously known as Tomohiro Tsurumi) (2010–2012), and Shohei (2012-Present).
Sadaharu Inui (乾 貞治 Inui Sadaharu?) is a highly intelligent player, who uses Data Tennis. He constantly collects and analyzes data of other players in order to determine weaknesses and habits. While he collects data pertaining to tennis, he also collects personal pieces of data, such as favorite things, personal habits, and where they have been, which makes others feel awkward. His style originates from his close friend, Renji of Rikkai, who played doubles with Inui before moving. He is temporarily removed from the regulars after losing to Ryoma and Kaidoh, and he becomes the team manager. He uses his data to create exercise programs for the team and creates a series of disgusting "Inui Juice" health drinks that are able to knock a person out, which motivates the team to train. He is voiced by Kenjirō Tsuda in Japanese media Erik Davies in English media, and portrayed by Hirofumi Araki in The Prince of Tennis live-action film.
Inui's data tennis allows him to predict the probability of a shot taking place although other factors can disrupt the probability. Though he relies on data, he still trains excessively to keep up with his teammates, taking on a training load 2.25 times more than Kaidoh's, which is already far ahead of the rest of the team. This allows him to reclaim his spot as a regular by beating Momoshiro, but losing to Tezuka. He pairs with Kaidoh in doubles to help Kaidoh train, and Kaidoh's massive amount of stamina is used to let him play alone while Inui rests and gathers data. The style does not work against Ryoma, who constantly evolves throughout each match, and he finds it difficult to collect data from players who do not play at their full potential, such as Tezuka and Fuji. He develops two extremely fast serves that are among the fastest in the Japanese tournaments. The Sonic Serve is developed first, which is trained with wrist weights, and the Waterfall Serve, its arc and descent resembling that of a waterfall engulfing the opponent, is developed afterward. His eyes are hidden behind his glasses throughout the series and only appears at the end of chapter 211.
In the musicals, Inui has been portrayed by Sota Aoyama (2003-2005), Hirofumi Araki (2005-2006), Masei Nakayama (2006-2007), Yuuta Takahashi (2007-2009), Yusuke Arai (2008-2010), Teruma (2010–2012), and Seiya Inagaki (2012–Present).
Takeshi Momoshiro (桃城 武 Momoshiro Takeshi?) is known as Seigaku’s "number one rascal." As the player who is the most open and friendly with everyone, Momoshiro is connected to everyone on the team on some level. Momoshiro is the closest to a true friend Ryoma Echizen can claim; the two spend much time together eating hamburgers or playing street tennis. Momoshiro and Kaidoh Kaoru are eternal rivals, and constantly try to out-do each other. This makes them efficient as a doubles pair, because the two rivals know each other so well. Momoshiro develops an affinity for playing doubles and even masters it, despite expressing a preference for singles. He loses his position as a regular after losing to Inui in the ranking matches. When Oishi injures his wrist before the match against Hyotei, Momoshiro takes his place to form a makeshift Golden Pair with Kikumaru. After that, he keeps his regular spot when Tezuka leaves for rehabiliation. After the nationals, he becomes the Vice-captain of Seigaku. He is voiced by Masaya Onosaka in Japanese media, voiced by Doug Erholtz in English media, and portrayed by Masaki Kaji in The Prince of Tennis live-action film.
Momoshiro's signature move is the Dunk Smash, a very powerful response to lobs as he leaps several feet into the air, which he likes to finish off saying, "Don," upon landing. He often fakes out opponents with a Dunk Volley. He later develops the Jack Knife, a strong backhand shot that is usually only used by professionals. In the anime, he develops the Super Dunk, a Dunk Smash that spins for a long time on the court before bouncing, thus confusing the opponent as to when it will bounce up. Momoshiro is good at "faking out" his opponents and can be extremely sly and tricky on the courts. His ability to read the opponent's movements and to observe their viewpoints and expression allows Momoshiro to guess where the ball will go and use shots that will confuse his opponents. He later improves upon this ability while training in the mountains, which allows him to be related with nature, and use it to his advantage, such as the position of the sun to blind the opponent, the direction of the wind to manipulate the ball, and stray stones to deflect serves.
In the musicals, Momoshiro has been portrayed by Eiji Moriyama (2003-2005), Masaki Kaji (2005-2006), Shinpei Takagi (2006-2007), Tetsuya Makita (2007-2009), Toshihiro Nobuyama (2008-2010), Toru Kamitsuru (2010–2012), and Masyu Ishiwatari (2012–Present).
Kaoru Kaidoh (海堂 薫 Kaidō Kaoru?) is known as "Viper" to his teammates for constantly making a "fshuuuu" sound similar to a snake while exhaling. Kaidoh trains rigorously, increasing the training program given to him by Inui to give him high endurance. He has a deep rivalry with Momoshiro, in which they constantly try to beat each other. Because they are rivals, they also know each other the best, and they can get along very well in times of need; this makes them an efficient doubles pair. He normally plays singles, though he eventually pairs with Inui, who helps Kaidoh train and develop new techniques. Kaidoh's stamina is used to let him play the other team alone, while Inui collects data. After the national tournament, Kaidoh becomes the new captain of Seigaku. He is voiced by Kōhei Kiyasu in Japanese media, voiced by David Lodge in English media, and portrayed by Kousuke Kujirai in the live-action The Prince of Tennis film.
His signature move is the Snake Shot, derived from the "Buggy Whip Shot", which is a curving forehand that keeps his opponents running. He later develops the Boomerang Snake, where the ball swerves around the net pole back in bounds. He develops the shot under Inui's advice and by working with him in doubles. He also develops the Short Snake, which goes directly behind the net player, the Reverse Snake, which is used to keep opponents guessing, and the Tornado Snake, which is a fast straight shot with a spin that cuts air resistance. He can also use Hiroshi Yagyuu's "Laser Beam", calling his version the Gyro Laser, which is an extremely fast shot with the same spin as the Tornado Snake, allowing him to confuse opponents. He also develops the Hadoukyuu Boomerang in the anime, which is developed from the Hadoukyuu that has much more strength behind a regular Boomerang shot.
Although he has a tough exterior and is cold towards others, there is a softer side to Kaidoh. Unknown to many, Kaidoh enjoys small animals, often taking the time to play with them. He is often seen playing with Ryoma's cat, Karupin, who wanders off on his own most of the time.
In the various TeniPuri Family episodes, Kaidoh is the young infant. Not being able to speak, he mainly just says "fssshhuuuu". Shuuko (Oishi) introduced infant – Kaidoh as "cutie-pie, Kaoru-chan". He is often bullied in some sorts by his older siblings, Ryoma and Momoko (Momoshiro).
In the musicals, Kaidoh has been portrayed by Naoya Gomoto (2003-2005), Kousuke Kujirai (2005-2006), Tomo Yanagishita (2006-2008), Yuuichirou Hirata (2007-2009), Akihiro Hayashi (2008-2010), Ryousuke Ikeoka (2010–2012), and Tatsunari Kimura (2012–Present).
Sumire Ryuzaki (竜崎 スミレ Ryūzaki Sumire?) is the coach of Seigaku's tennis club and one of the school's math teachers. She helped Nanjiroh Echizen develop his skills and become a professional tennis player. She has a granddaughter named Sakuno with a crush on Ryoma. Ryuzaki has a rivalry with her ex-mentor, Mikiya Banda a.k.a. Banji, who is the coach for Yamabuki. She constantly yells, but she is considered to be a great and reliable coach. She has a good relationship with her regulars and participates in their recreational group activities: the bowling reunion and the beach-volley mini-tournament with Rokkaku Middle School. For the Prince of Tennis live action movie, Ryuzaki's whole personality and back story was changed. Instead of being a middle-aged teacher and ex-coach to Nanjiro Echizen, she is a young and more cheerful woman as well as Nanjiro's former classmate, who was her reason for playing tennis and becoming coach. She was played by the popular singer Hitomi Shimatani.Voiced by: Shizuka Okohira (Japanese), Barbara Goodson (English)
Fudoumine Middle School (市立不動峰中学校 Fudōmine Chūgakkō?) is an unseeded and unknown public school with rumors of violence. It was originally unknown due to an unreasonable coach and a lazy set of senior regulars. The freshmen at Fudoumine were brutalized severely by the older tennis club members, while the coach ignored the mistreatment. Tachibana and the abused freshman attempted to rally together and form their own tennis club, but the coach and the other players find this idea absurd and try to stop this from happening. When the coach allows his older team members to attack Tachibana and the freshman, Tachibana snaps and attacks the coach. As a result, Fudoumine is pulled out of the District Tournament that year. Tachibana and the others eventually reform the club, and in the series, upsets Kakinoki in the District tournament semifinals and Hyotei in the Prefectural quarterfinals. They go on to make it all the way to the quarterfinals of the Nationals before losing to Shitenhouji. Fudoumine's uniforms are black hooded jackets with the Fudoumine logo, black shirts, white shorts, and black warm-up pants.
- Kippei Tachibana (橘 桔平 Tachibana Kippei?) is the captain of Fudoumine. He was originally from the Kyūshū region of Japan, where he attended Shishigaku Middle School. He and his close friend, Chitose, led their team to the semifinals of the Nationals as the top two players of the region. Tachibana is a very aggressive player, and during an intra-school ranking match, he injured Chitose after deciding to try out his new move, the Wild Ball, which makes it look like there are numerous balls coming at one time. He cuts and stops bleaching his hair, moves with his father and sister, and eventually starts with the Fudoumine club in order to play Chitose again. He uses the "Moujuu Aura", which draws out his natural style and increases his physical abilities, especially when using his "Abare Dama" frame of racket shot, as well as the "Abare Jishi". In New Prince of Tennis he is one of the players invited to the Japanese U17 team. He is voiced by Yoshihisa Kawahara in Japanese media, and Doug Erholtz in English media. He is played by Takuma Sugawara, YOH, Takashi Kitadai and Yuusuke Ueda (2nd season) in the musicals.
- Akira Kamio (神尾 アキラ Kamio Akira?) is the vice-captain of Fudoumine, who normally plays singles or doubles with his long-time friend Shinji Ibu. His style focuses on speed and "rhythm" of his feet. He uses the "Sonic Bullet" shot, which seems to disappear, and the "Quick-Drop Serve", which is hit before it rises to the top, throwing off the opponents timing and slightly increasing the speed. He has a crush on An, and is jealous when she goes out with Momoshiro. In New Prince of Tennis he is one of the players invited to the Japanese U17 team. He is voiced by Chihiro Suzuki in Japanese media, and by David Neil Black in English media. He is played by Matsui Yasuyuki, Yuki Fujiwara and Kinari Hirano (2nd Season) in the musicals, and Yuki Fujiwara reprises that role in the live action film.
- Shinji Ibu (伊武 深司 Ibu Shinji?) normally plays singles or doubles with his best friend Akira Kamio. He often mumbles and rambles without realizing other people can hear him. He utilizes the "Kick Serve", which bounces upward to the right, similarly to the twist serve. In New Prince of Tennis he is one of the players invited to the Japanese U17 team. He is voiced by Eiji Moriyama in Japanese media, and Kirk Thornton in English media. He is played by Ryōsei Konishi, Motohiro Oota and Kazuhiro Okazaki (2nd season) in the musicals, and Yasuka Saitoh in the live action film.
- Tetsu Ishida (石田 鉄 Ishida Tetsu?) normally plays doubles with Masaya Sakurai (桜井 雅也 Sakurai Masaya?), who has a special shot with a heavy topspin. He relies on the Hadokyuu, an extremely powerful flat groundstroke that can reach 120% of the user's strength, which he learned from his elder brother Gin. It puts an extreme strain on his arm at first, which cause Tachibana to disallow him from using it until he masters it. Tetsu Ishida is played by Mamoru Miyano and Kyoushirou Takagi (2nd season) in the musicals, and Masaya Sakurai is played by Shun Takagi and Fumiya Takahashi (2nd season) in the musicals.
- Kyousuke Uchimura (内村 京介 Uchimura Kyōsuke?), nicknamed "The Forward Net Killer" plays doubles with Tatsunori Mori (森 辰徳 Mori Tatsunori?). Kyousuke Uchimura is played by Mao Katou (2nd season) in the musicals, and Tatsunori Mori is played by Youichiro Omi (2nd season) in the musicals.
- An Tachibana (橘杏 Tachibana An?) the cute younger sister of Kippei. She is a member of the girls tennis club, and often supports her brother's team. An cares very much for her brother and her friends from both the Seigaku and Fudoumine teams and tries to help them as much as possible. She is voiced by Akiko Kimura in the Japanese media, and Jennifer Sekiguchi in the English media.
St. Rudolph (私立聖ルドルフ学院中学校 Shiritsu Sei RUDORUFU Gakuin Chūgakkō?) is a team that first appears in the Tokyo Prefectural Tournament Arc and faces Seishun in the quarterfinals. The school itself only recruits students who are gifted at tennis and they only practice together once a week. The team uniform is a white shirt with brown, brown shorts, and brown warm-up pants.
- Yoshirou Akazawa (赤沢 吉郎 Akazawa Yoshirō?) is the captain of the team and the doubles partner of Ichiro Kaneda, a soft spoken player called a "prodigal doubles player." He is initially a singles player until being paired with Kaneda by Mizuki, which leaves him unable to properly play until Kaneda, who normally looks up to Akazawa, yells at him. The pair of Akazawa and Kaneda provide St. Rudolph's only victories in their losses to Seigaku and Hyoutei. Akazawa also defeated a Seigaku regular in the year prior to the manga's storyline.

Hyoutei Academy Secondary Department (氷帝学園中等部 Hyoutei Gakuen Chūtō Bu?) is a team that uses a strict stratification and merit system, which prioritizes ability over emotion. If any regular loses a match, they are removed from their spot and only given a second chance in very rare conditions. With Keigo Atobe as their leader, the one who revolutionized the merit system on the team, Hyoutei's tennis club is composed of over two hundred members. Widely considered as the main contenders to Rikkai Dai, they instead suffered setbacks in the early tournaments, losing to Fudomine in the quarterfinals of the Prefectural Tournament, and then losing to Seigaku in the first round of the Kanto tournament, leaving them ineligible for the National tournament. They are all depressed until they receive a special invite due to the host city, Tokyo, getting to invite one extra team. According to Takeshi Konomi, Hyoutei's popularity was much higher than he expected, and it was for that reason that he chose to bring them back into the story. The Hyoutei team is one of the most popular teams in the entire series. In the official school popularity poll, they came in second losing only to Seigaku.
- Keigo Atobe (跡部 景吾 Atobe Keigo?) is the captain of Hyoutei. As a former European junior champion, he was relatively unknown in Japan until he defeated all of the members of the team in his first year and the Seigaku captain in his second year. He is severely narcissistic and arrogant, often using the quote "Be awed at the sight of my prowess!" (Ore-sama no bigi ni yoi na 俺様の美技に酔いな?). He is very wealthy, and he owns various chateaus, mansions, and vehicles, which are often used to benefit the team. Despite his personality, he trains constantly and takes pride in the team. He has rivalries with Tezuka, who he defeats in the Kantō Tournament, Sanada, who he would have defeated in a practice match but Yukimura called it off, and Ryoma, who he loses to in the nationals. Atobe, using his superior eyesight, is able to use "insight" to quickly determine another player's weakness, which he uses to his own advantage. He eventually develops it to the point where he is able to anticipate the spin of the tennis ball by looking at the way his opponent hits it and apply the proper counterspin. He evolves it even further into his "World of Ice" (氷の世界 Kōri no Sekai?), which allows him to find dead angles a player is unable to reach and hit balls with pinpoint accuracy and timing towards these areas. It can, however, be broken by applying the Tezuka Zone to direct the ball away from those dead angles. He also uses the Rondo Towards Destruction (破滅への輪舞曲 Hametsu e no rondo?), a powerful smash that knocks the opponent's racket away and allow Atobe to smash it once again, and the Tannhauser Serve, which spins rapidly down the court instead of bouncing on impact, making it hard to hit. Atobe must exert enormous force in order for the serve to come out correctly, thus slowly worn down over time. Since his initial appearance, Atobe has become one of the most popular characters in The Prince of Tennis series. According to Takeshi Konomi, fans initially didn't like Atobe when he was trying to destroy Tezuka's arm, but by the conclusion of the match, he had become one of their favorite characters. In the 4th characters' popularity ranking, Atobe was voted first with a total of 12,913 votes, soundly beating Shusuke Fuji, who came in second with 6116 votes.

His main rival is Tezuka, who he lost to despite being the runner-up to Yukimura in the Junior tournament, and vows to train and defeat him. He uses a family of techniques called "Wind, Forest, Fire, Shadow, Mountain, Lightning" (Fuu Rin Ka In Zan Rai?), though he initially seals off Shadow and Lightning to prepare for the match with Tezuka. Wind, based on the drawing of a sword, leaves the ball nearly invisible to the eye. Forest neutralizes the spin of a ball. Fire is a powerful shot that can be hit as a smash, forehand, or backhand. Shadow hides his weaknesses and makes him unreadable, particularly against the Saiki Kinpatsu no Kiwami.

Originally discouraged to join Rikkaidai because he thought he could be the number one player, Sanada eventually convinces him to join and strive to someday defeat the Three Demons. He usually acts childish and friendly, though he is actually very violent on the court, often causing serious injuries that require hospitalization. He reforms in the anime after being beaten by Fuji, (though he retains his nature in the manga) but in the nationals, he returns to his violent playing style, severely injuring Inui.

- Kenjiro Koishikawa (小石川 健二郎 Koishikawa Kenjirō) is the vice-captain, but has almost no role in the story. He was originally intended to play a larger role, but this was cut when Konomi had to move Chitose to Shitenhōji, and the team wound up with an extra player.
- Senri Chitose (千歳 千里 Chitose Senri?) originally played on the Shishigaku team with his close friend, Kippei Tachibana where the two guided Shishigaku to the National semi-finals in the previous season.

He is Hyoutei's Yuushi Oshitari's cousin. He plays doubles with Hikaru Zaizen and sometimes Ishida Gin, but he selflessly agreed to sit through the Nationals semifinals so that his teammate, Chitose, could play Tezuka in the Doubles match that Kenya should've been in. Zaizen calls him "hetare" sometimes, which refers to how he is clumsy and weak-brained, such as the scene in Another Story OVA where he effortlessly runs past the Seigaku team despite arriving late, and, as he is laughing, crashes into a signpost and trips, falling to the floor. Kenya is voiced by Jun Fukuyama in Japanese media, and played Takuya Uehara, Kouki Mizuta and Masato Saki (2nd season) in the musicals.

Koharu uses data tennis, determining how to counter shots with his IQ of two hundred, allowing him to store a large amount of data. Yuuji impersonates other players' voices after studying. They break up after they lose to Seigaku; while Yuuji is heartbroken and still chases after Koharu, Koharu assumes the typical "girl-bratty" personality, rejecting the boy and even tearing up some of the pictures he had of Yuuji in his bag (from fanbook 40.5, Shitenhouji bagchecks).

He uses a "Wild" tennis style (and acrobatic play) that takes advantage of his natural stamina and strength, being able to lift a scooter over his head and throw it with ease. His signature technique is the "Mountain Storm", during which he spins rapidly in the air, causing a massive amount of wind to stir, and delivers a powerful overhead smash stronger than Gin's strongest hit. Chitose finds Kintaro as the player closest to achieving Tenimuhō no Kiwami. Kintaro is extremely afraid of Shiraishi, after reading a manga about monsters with poison claws, and as such, his unbound imagination comes up with the peculiar idea of Kuranosuke having poison claws under the bandages that he always wears around his hands and arms (this is a reference to Konomi's previous manga series; Cool -Rental Body Guard-). This fear is used to keep him in line. Kintarō's knowledge of Japanese is also shown to be weak, and he misreads the Kanji of Ryoma's family name 'Echizen' as 'Koshimae'. He is voiced by Yū Sugimoto in Japanese media, played by Yuuya Kido, Takuya Kawaharada and Kodai Matsuoka (2nd season) in the musicals, and by Masato Wada in the live action film.

He is the only member that is able to use the "Shukuchihou" in any direction due to his balance. He also teaches them their signature techniques. Kite remains composed and polite in front of other teams, yet extremely condescending towards them, and if physically attacked, won't hesitate to strike back. His tennis style combines the "Shukuchihou" with other techniques such as his powerful "Big Bang" serve, and his "Habu", a shot that curves randomly, making it extremely difficult to return. Kite is one of the middle schoolers invited to the Japanese U17 team in New Prince of Tennis.

- Kei Tanishi (田仁志 慧?) possesses a large body, which allows him to utilize his "Big Bang" serve that uses his weight and the gravity from falling in order to make a nearly unreternable serve.

He is one of the former rivals of Ryoma who return to help him regain his memories. In New Prince of Tennis, he is among the 50 middle school players who are invited to the Japanese U17 team. He is voiced by Youji Ueda in Japanese media, and played by Yutaka Matsuzaki and Yuuki Tomotsune (2nd season) in the musicals.
- Rin Hirakoba (平古場凛?) is the only member who likes fair play. He uses Habu, which has the stance of a smash, except that it curves wildly and unpredictable while in the air and bouncing, and Giant Habu, which curves immediately after leaving the racket, though it causes his hand to go numb, limiting it to one use per match. Hirakoba is a very formidable player, being able to take out Fuji's triple counter and Takashi's Hadoukyuu. He is one of the few players to stand up to Coach Saotome, refusing an order to attack Seigaku's coach feeling the match was too interesting.
