At the Training Ground.
Hiss, hiss, hiss—
A breeze stirred. As the chakra spun, it whipped up a visible blue vortex. Naruto Uzumaki held out both hands, pride written all over his face.
"Sasuke, you haven't learned this jutsu, have you? Hahaha!"
Sasuke glanced over his shoulder.
He was a little surprised.
But his face remained impassive.

The Rasengan really did look like a loose ball of yarn dropped on the ground.
Strands began to
