It's August 19th, and summer vacation is almost over. And at the end of summer comes the big joint festival, held between the seven schools participating in the Kanto Regional Tournament, and hosted by their tennis clubs. With a prize for the best festival entry, the competition among the clubs is fierce, with each school's glory riding on their festival booth. You play as an 8th-grade girl, a member of the Student Festival Committee, assigned to assist your school's tennis club. After being introduced at the Committee meeting, it's clear you'll be working with some pretty strong personalities... But it's going to be up to you to help them make this the best festival it can be, and win first prize for your school's entry! With only 10 days to go until the festival, what exciting encounters could be in store...?
