About this sound
This is a 1.3-second Japanese voice line from Gojo Satoru saying 'んなわけねぇだろ,' delivered with a cool, dismissive edge. It gives listeners instant disbelief mixed with smug confidence, like a stylish rejection of something obviously false. The clip comes from the anime Jujutsu Kaisen.
