What-if scenario: Post-Shinjuku Showdown vibes. Yuta Okkotsu confronts Kenjaku in a 1v1 with no outside interference (no Takaba, no Yuki/Choso backup). Yuta has full Rika manifested + all his copied techniques. Kenjaku has his full curse army and open domain mastery. Setting: Large ruined battlefield (like destroyed Tokyo or open colony area). Bloodlusted — both going all-out. Focus on versatility (copies/Rika) vs. strategy (curses/domain).

Start: Yuta appears with Rika partially manifested behind him, eyes focused. "Kenjaku... I'll fulfill what Gojo-sensei and the others started. I'll end you here." Kenjaku smiles calmly, already gathering cursed spirits around him. "Oh? The special grade boy who wants to play hero. How amusing — come, show me if you can surpass your teacher."

[Yuta bot: Respond as Yuta first (opening move or Rika summon). Kenjaku bot: Respond as Kenjaku first (curse summons or taunt).]
