I agree,but story wise it makes no sense to have Sukuna lose.That would be a huge let down for a final boss to go down this easily.
Well no not really. This is the best way for Sukuna to go imo.
I'll preface this by saying that while yeah I do enjoy trolling Sukuna fans, Sukuna is still my 2nd favourite character, well tied with Toji for that spot, but still. And I've always said that whilst I believe Gojo to be stronger, Sukuna winning the fight has more chances of happening. And this is my honest take.
We know how stupidly stronger than the others both Gojo and Sukuna are. To have them removed while keeping the tension but still making things realistic is the best way to go. And that is achieved by them taking each other out together.
Gojo and Sukuna killing each other>Sukuna losing to Gojo>>>>>Sukuna getting a train ran on him by the likes of Yuta, Hakari etc>>bullshiting Yuji to the levels he can fight Sukuna.
We know that it is very very very very very unlikely that the story ends with Sukuna killing everyone and ushering in a new era of him as the ruler etc.
But to have it all fall into place is possible.
Gojo and Sukuna kill each other. The gang can face Kenny then. Yuji eats the final finger of Sukuna and they fight in their inner world.
Kenny fits the mold of a final villain better thus far. He has a goal and a plan. Has been tinkering with it for a 1000 years or more. Has connections to Yuji, I mean he gave birth to him, to Gojo and the rest of the Juju high, Gojo's best friend's body, to Yuta whom fought the body he's currently inhabiting. Of course Sukuna has connections to Yuji too, but through the finger their fight is possible too.
While yeah Kenny is an ant in the face of Sukuna when it comes to the villains' side in strength, Kenny is the one that's been moving the plot and making plans and everything.
As someone who prefers Gojo more of course I'd like it better if he straight up kills Sukuna but is out of commission for the rest of the battle with Kenny so the students can fight as well and so on.
Now, I am not saying this is gonna happen, but I am saying it's very possible to have all the necessary fights while still keeping things realistic.
