The purple-black lightning in Sasuke's hand darted around like a rabid dog.
Its crackling beside the filthy pool scraped painfully against everyone's eardrums.
The ozone stink of scorched flesh blasted straight up their noses.
His deathly pale face twisted into a knot.
The veins on his forehead bulged wildly, one after another.
"Sen Senju, I'm going to kill you today."
Sasuke forced the words through his bloodstained back teeth.
