"Lightning Release..."
Sasuke's voice rang out slowly through the Arena.
The next instant, a piercing chorus of birdsong erupted.
"Chidori!"
Crackle!
Violent lightning danced wildly in Sasuke's hand, dense arcs of electricity shooting out in every direction.

"Water Release: Water Formation Wall!"
Chojuro rapidly formed hand seals.
The water surged upward with a roar,
