Princess Nine

As Ryo Hayakawa arrives home from school, the local baseball team begs her to finish pitching their game.

The chairwoman at the Kisaragi School for Girls has determined that there will be a girls' baseball team and that they will go to Koshien within three years. Ryo is offered one of the scholarships issued to build this team.

Ryo is accepted into Kisaragi School but worried about leaving her mother to run the Oden bar by herself.

Coach Kido has been told that one of their recruits, Seira Morimura, has refused to join the team.

Coach Kido goes to the Oden bar and shows Ryo a tape of a baseball player with a famous batting technique called the Wave Motion Swing.

None of the players can catch Ryo's pitches and so a search for a catcher begins.
