Name: Shinjou Reiji
School year: Three
Position: Regular
Special moves: Mirage, Deep Impulse
Plays against: Ryouma
Basic information:
Shinjou is Jousei Shounan's ace and whom Hanamura sees as her best masterpiece. He is always serious does not really talk much about himself. He respects Hanamura and like the rest, he does not mind being called a 'masterpiece'. Shinjou's special abilities include Mirage, where he is able to hit hard or soft serves without changing his form thus confusing opponents, and Deep Impulse - a move designed to hurt his opponent. Even so, it is far less serious when compared to Akaya's demonic intentions. Deep Impulse is forbidden, as told by Hanamura, but he broke the seal when Ryouma insulted her, which shows how much his coach means to him.

Name: Wakato Hiroshi
School year: Three
Position: Regular
Special moves: Change Over (Imitation)
Plays against: Kaidou
Favorite quote: Kimi ni pittari no sutairu ga kimatta! (The perfect style for you has been decided!)
Basic information:
Wakato acts like a playboy and is the idol of the girls in his huge fan club. He can be haughty and cheeky, and once quite insulted Seigaku and Kaidou, which was the cause of Sumire insisting that Kaidou be his opponent in Singles 3. Wakato's ability to imitate people may sound familiar to Kabaji's 'Copy', but there actually likes a big difference. Wakato is exceptionally good at imitating and learning people's moves and even stances and habits, but behind all the imitation lies long days of training and practicing, which means that he is not capable of imitating something totally new on the spot. This also proves his level of hardworkingness, though he may not seem like it. During the match against Kaidou, he managed to hit a Boomerang Snake but was unfortunately unsuccessful.

Name: Kajimoto Katsuyuki
School year: Three
Position: Captain, regular
Special moves: L. Drill Serve
Plays against: Momoshiro & Kaidou
Basic information:
Unfortunately, the captain of Jousei Shounan did not get to play in the match during the Kantou Regionals. Decent and mature, Kajimoto proves to be Jousei's most suitable captain though he is not the #1 masterpiece. He later appears in the episode where he teamed up with Mizuki to play against Momoshirou and Kaidou in a match that supposedly should decide for one of them to join Jousei Shounan. Kajimoto breaks everyone's record in performing the fastest shot that goes up to a speed of 195km/h (122miles/h) with his L. Drill Serve, which is even faster than Choutarou's Scud Serve.

Name: Kiriyama Daichi
School year: Two
Position: Regular
Special moves: Cannon Volley, Thunderbolt (Combination with Oota)
Plays against: Ooishi & Kikumaru
Basic information:
Daichi is literally a giant for someone his age. He rises to a height ot 195cm (6'6"), and looks like he's twice the height of Oota when standing beside him. Unlike Kabaji, Daichi is not the wordless type, but rather quite the showing-off, and one who is proud of his own built. When playing doubles with Oota, Daichi mainly stays near the net where he can reach the ball in only 2~3 strides.

Name: Oota Shou
School year:
Position: Regular
Special moves: Thunderbolt (Combination with Daichi)
Plays against: Ooishi & Kikumaru
Basic information:
Oota is the extreme opposite of Daichi, so short he's smaller then even Ryouma and barely stands above Daichi's belly. Teaming up with Daichi forms the story's most unique doubles pair, which at the same time enables them to perform a move no other can - Thunderbolt. Thunderbolt is a move where Oota jumps on Daichi and over him high up to return even the highest lob and turn it into a fearsome dunk. Due to the combination in height and the additional jump, the power of this dunk is gained from a height of 278.5cm (~9.28 feet) and from the most ridiculous angle.

Name: Youhei
School year:
Position: Regular
Special moves: Duo Union (Combination with Kouhei)
Plays against: Inui & Kaidou
Basic information:
Youhei and Kouhei are twins, Youhei being the elder. They play doubles together and share the same special ability - knowing where a ball would land just by hearing the impact of the ball against the racket. In addition to their modified hearing, they also have good vision.

Name: Kouhei
School year:
Position: Regular
Special moves: Duo Union (Combination with Youhei)
Plays against: Inui & Kaidou
Basic information:
Same information as Youhei (above).

Name: Hanamura
Position: Coach
Basic information:
This pretty coach of Jousei Shounan calls her coaching style Coordination Tennis. She is interested in those who are potentially strong, or whom she sees a talent in, and is determined to nurture them to become what she calls her masterpieces. She was also interested in Ryouma and tried inviting him to Jousei Shounan but was bluntly rejected. She was also responsible for the Kaidou & Momoshirou vs Kajimoto & Mizuki match in an episode later after Seigaku played against Jousei Shounan.
