Jazz
Remember Jazz from the Ball Races at the Rokkaku Expo Stadium?
Well if you go back to the Stadium in Chapter 7,8 or 9 and beat Jazz in a race around the stadium you will acquire her as a new GG member. If memory serves correctly she had identical stats to Rhyth.
The race is simple. Once you're a good distance ahead just do as you did the Ball games.
