Gojo is proud of himself for having finally found a strong opponent (Potentially stronger than Sukuna or Gojo), and now, he's ready to go all out. (No, Gojo ain't the main character of this animation.)
I took a scene from Gojo and Toji's rematch from season 2 of JJK, added the blindfold, changed the clothes, and traced the hair from another image of Gojo.
