Freshman tennis prodigy Ryouma Echizen and the Seishun Academy Boys' Tennis Team have finally reached the National Tournament, eager to fight for the championship title and claim it as their own.

Awaiting the winners of the matchup in the quarterfinals is one of Seishun's old rivals: Hyoutei Academy, who are determined to restore their pride after the events at the Kanto Regionals. Hyoutei seeks to prove to everyone that they deserve to be at the Nationals despite only qualifying through a special invitation.
