Yes. I guess in some respects you could think of it as a more fleshed out RPG version of Blitzball, with a whole game built around that.
Anyway, you have a story mode, which takes place in your school, and like a standard RPG you have exploration where you can root through dressers, talk to NPCs, and the like. Through this you can also recruit a thousand (literally) different characters. Characters level up, increase their stats, can equip different abilities... The gameplay seems to consist of a field where you move your characters around by drawing paths via the stylus. When you encounter an enemy and try to steal the ball, or defend it, you go to a menu-based battle system where you use different command skills to defeat the opponent.
