Gojo is obviously gonna survive this moment somehow but Sukuna will definitely win.
Even if you just analyze the flow of the fight it’s pretty clear.
Character 1 (Gojo) gets strong beginning (223 + 224) -> moment of dread where character 2 (Sukuna) gets the upper hand (225-?) -> Character 1 figures something out and regains advantage -> Character 2 brings out full power/trump card and wins.
This is a pretty standard formula, you can see it in a lot of scenarios where a strong good character loses (think like Jiraiya vs Pain).
It’s pretty obvious imo
