Eiichirō investigates going Pro, but his reaction from his parents is less than he expected. Eiichirō joins Natsu at the first round of the All Japan Pro to watch the debut match of Ike Souji.

Eiichirō participates in a tournament after 3 months of hellish training. He learns about active rest while participating in the tournament and makes it to the final. Terashima is his opponent.

Yu Nabae matches up with Eiichirō and realizes they really are two players that are virtually the same. He realizes that what Eiichirō lacks is experience with the fundamentals, as he has never played anyone like himself, and after losing the first set Nabae begins to pull away and goes up 5-2.

Eiichirō runs to watch Natsu's match when he learns she is in danger of losing. Afterwards they return to STC where he Ryuhei Aoi, a man who will become his new coach.

Eiichirō arrives in Florida, and Coach Mike introduces him to Marcia, an upcoming junior whose older brother just made the Pro's. Marcia and Eiichirō play a match, and Marcia decides Eiichirō must be training for the French Open because of his slow play style.

Eiichirō begins closing the gap on the others at the Florida Academy, but during everyone of his matches he has one moment where he presses too hard, costing him a set and eventually costing him the match.

After winning his first match in America, Eiichirō finally gets to play Ike in a one set match. Ike gets it approved at the New Years party where many of Eiichirō's new friends first learn of Natsu.

In his final day in Florida Alex agrees to play a best-of-3 match with Eiichirō. Alex realizes that Eiichirō's notes contain all of his weaknesses and that he will have to adjust his play style to win the match.

Eiichirō returns from Florida and is given a day off to adjust his body to the time difference. After the day off Eiichirō begins a new strict training regime to help him get ready for the Kanagawa Prefectural.

Coach Aoi explains to Eiichirō that he stopped the match against Takuma because his body wasn't developed to serve like Takuma yet. If he had continued to serve that way, he would have injured himself and forced himself to give up his tennis career.

The Kanagawa Prefectural begins as Eiichirō faces off against Araya's new underclassman Nishimura. Araya has told Nishimura all of Eiichirō's weaknesses from the year before, making Nishimura very confident in his chances of winning.

Eiichirō and Miyagawa face off in the second round of the tournament for their second match. If Eiichirō loses he knows he'll lose all chance of going pro. If Miyagawa loses he knows his path to become a pro will take longer and might force him to go to college first.

Coach Ryuhei Aoi decides to teach Eiichirō the importance of relying on instincts during a match instead of relying solely on data. In order to teach him how to play against a player who relies solely on instinct Eiichirō is forced to face off with Natsu.

Araya and Eiichirō begin their match in the Kanagawa Prefectural Final. At first both are holding serve and the score is at 3-3. However Coach Aoi realizes Eiichirō doesn't have the knowledge on how to deal with left handers since he's only played Araya once.

Eiichirō throws out a couple of unexpected dropshots in set 2 and begins to alter the speed of his game. After trailing 30-love to begin match 2 of set 2 Eiichirō is able to rally with this new strategy and pull off a break.

Araya and Eiichirō prove to be even and are both unable to break each others serve. Making things worse is there will be no tiebreaker., Instead an individual must win by 2 games.

The gang begins their third and final year of high school in different classes. Eiichirō and Natsu both realize their classes seem to be moving on without them as they are getting ready for cram schools and entrance tests.

The final door on the way to the All-Japan Junior, the Kanto Junior Tournament, is just around the corner. Eiichiro psyches himself up as he confirms his promise to his parents that he'll give up if he doesn't win the All-Japan Junior, and then he sets off with the other STC members for Chiba, where the Kanto Junior will be held.

The Kanto Junior Tennis Tournament begins at last, and Eiichiro is facing Yakabe Tadanori in his first match. Although he had watched videos of Yakabe's matches from a year ago, Eiichiro is bewildered by his opponent's much taller stature and completely different play style, and all the unexpected factors lead him to consider blanking all his mental data and starting from scratch.

Eiichiro is stunned by all the cheering Ide receives as their match begins. He struggles with the unpredictable plays of the intuitive Ide, but he recalls what he learned in his match with Natsu and concentrates on watching his opponent. Meanwhile, Ide also struggles to keep up with Eiichiro's constant changes in tempo and starts to tune out the world as he tries to focus.

Ide's remarkable ability to adapt instantly to everything has Eiichiro struggling, and reads his notes again to regain his focus. This improves his movements and leads to more impressive rallies, making the match even more exciting. Neither is willing to yield as the match comes down to which player can manage to hold serve...

Eiichiro thought he was successfully ignoring the crowd's roaring cheers for Ide, but his body was reacting to it more than he realized. The pressure of playing in front of a dramatic, Ide-centric crowd is troubling Eiichiro.

Eitaro, upon winning spectacularly in his fight against Ide, decides to go to the National Junior's. Coach Aoi explains that towards the end of the match, Eitaro was completely in the zone.

The match against Takagi begins. Just as Yukichi warned, Takagi's style is unique.

Even if it seems to lack etiquette, Takagi's play style continues to work in his favor by disupting his opponent's pace. Eiichiro struggles to deal with Takagi's tactics.
