After Nationals and before attending the U-17 Japanese team training camp, the middle schoolers enjoy a moment of free time. Tezuka goes lure fishing with his grandfather Kunikazu. Oshitari Yushi and Kenya get heated over a lottery in a shopping mall. Shiraishi is told a shocking truth by his sister Yukari as he cares for his rhinoceros beetle.

You can’t refuse a challenge from someone wearing a black jersey. The losers are back and court 2 players are their first victim. Meanwhile, Ryoma has a score to settle.

Mifune has increased the training for the junior high and high school students. To sweeten the deal, he has offered both groups a valuable prize, and it’s going to be big.

With Tezuka gone Atobe is the new team leader and has a lot to prove. In a match against Irie, Atobe is dominating until Irie’s true nature is reveled. The pressure is immeasurable, and it’s starting to show.

A former Seigaku tennis player makes a surprise appearance while Ryoma is training, inviting him to witness his match against Tezuka. And before the end of the match, Tezuka’s secret will have been revealed and a life altering decision made.

The results of Mifune extreme training are becoming apparent but Echizen is not satisfied and demands a match. While the players at the Under 17 camp have hit a wall and a team shuffle has been announced.

As the team is woken up at night to practice, Echizen and two others are selected to break into the U-17 Camp. However, they find this might be more difficult than expected require a few Ina Bauer!

Mifune drinks hard, yells, and he is the coach of the losers. His methods are ancient and he pushes the campers to the mental and physical limit. But there may be a method to his madness.

The winners are being subjected to a grueling training campaign as the losers ridding the bus home. As the bus stops unexpectedly, Coach Saitoh is waiting with Echizen and Kintaro; he is offering all the losers a chance to redeem themselves.

Tezuka is dominating in his match against Kaidoh, but continues to draw the game out. On the next court, Atobe is teaching Hiyoshi what it means to be number one.

After picking a partner, the campers are informed they will have to play against each other. This causes strife as Seigaku’s golden pair are going to play for who gets to stay at camp.

Takeshi Momoshiro is the first Seishun student to play against a staff member. Unfortunately he is against Jujiroh Oni, the man with a 2 string racquet, the Gatekeeper of Hell. Is Momo strong enough to withstand the onslaught from the Gatekeeper?

Seishun Academy Tennis Club has been invited to the exclusive Under 17 training camp along with their rivals. This is a first, as the camp has never invited a middle school team. The training staff has devised a plan to narrow the list of potential campers. Will Ryoma make it in time?
