The Seigaku tennis club has been invited to train at the U-17 (Under 17) camp. Seigaku is one of the 50 middle schools invited and must compete with high school players to prove they are just as good.
"Seigaku and other middle school students (with a total of 50 middle school students) are invited to the U-17 selection camp. Ryoma also comes back from America to participate. The high school students there dislike the middle school students."
"Tezuka plays Kaid\u014d and Atobe plays Hiyoshi. Both captains have a plan from the start to teach their juniors a lesson before defeating them. Meanwhile, Ryoma and Kintar\u014d are playing matches with Tokugawa and Oni."
"The winning middle school team start the next stage of their hard training right away. The losers face the biggest challenge of their lifetime given to them by the mental coach, Sait\u014d."
"At the training camp in the mountains, the middle schoolers are given rackets filled with lead and are forced to hit balls with the rackets. Meanwhile, in the U-17 camp, Court 5 have team shuffle matches with Court 3."
