Arata's been watching the spectacle not far from them both - hiding behind a tree until he's finished his calculations and gathering his data.
Once that's done, though... well, hopefully they don't mind an interruption, because he's speeding out and sliding that ball away from Gallade; stopping just to kick the ball on his knee and give her a cocky looking grin.

After that - well, it's time to show off, right? Which is just what he'll do! He kicks runs towards one of the goals, skillfully dribbling it, before taking it and himself up into the air for a shoot - one that Rosa's probably never seen in her life.
That is - his foot seems to catch fire as he spins up in the air, the ball turning into a huge ball of flame as it streams into the goal. Fire tornado, anyone?
