Jujutsu: The Strongest on the Forums, or the Strongest Four Hundred Years Ago?

[Jujutsu Kaisen] [Culling Game] [Pure, action-packed combat] [No romance] [I have completely grasped the core of cursed techniques] [Worldbuilding Expansion Project] [The kids will win] “Let me make this clear first: you’re the challenger!” A legendary figure in the debate scene, wielder of the Executioner’s Lightning, a man without a Domain, Reverse Cursed Technique, or Maximum Technique, and the strongest in four hundred years launches a challenge against Sukuna! The absolute ruler of the debate scene, the most ferocious man born of it. The one who taught you how to wield lightning is… “Kids, I watched an ad and got revived. Send me 50 and I’ll take you to Shinjuku to fight Satoru Gojo and Sukuna.” Kashimo, who died after being cut down by the Grid Slash, is reborn. This time, armed with absolute intel, he is determined to prove his strength. What?! Just what?! Four hundred years of fierce rivalry!! Who will emerge victorious: Gojo and Sukuna, or Kashimo with his absolute intel? Either outcome is possible. That is the answer.
