A former Seigaku tennis player makes a surprise appearance while Ryoma is training, inviting him to witness his match against Tezuka; Tezuka's secret will be revealed and a life altering decision will be made.

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.

As pairs are forced to defeat their partners in heartless matches to keep their spots at the training camp, Yukimura and Sanada, top players of Rikkai, face off. Sanada announces his desire for a head-to-head battle and uses his “Fuu Rin Ka Zan” as soon as the match begins.

Shiraishi and Kenya are the next friends to face off. Though they've long fought together for the same school, they haven't played each other since last summer. Kenya had been avoiding playing Shiraishi because of the events of the previous year's Nationals.

The winners remaining at the training camp practice hard and enjoy its luxurious facilities and meals. However, Kikumaru and Otori are disheartened by their separation from their partners. As they commiserate with one another, Atobe and Mizuki harshly state they can't afford to worry about the losers.

Swearing to Shishido that he would become stronger, Otori remained with the winners at the training camp. His turn has finally come in the shuffle matches. Otori enthusiastically faces high schooler Enjoji, but when his Scud Serves prove useless, he loses the match.
