Welp yall better check spoilers for chapter 268 in case of who wins this battle lmao

Also gege said it would be one from main 3, not 4 - Nobara, Megumi and Yuji, without Gojo, he was part of the previous 3 with Geto and Shoko. That's why people are suspicious about what we see in chapter 268:

SPOILER WARNING

Megumi gets separated from sukuna who turns into dust, him Yuji and Nobara are all alive and safe. This is too much of a happy ending for someone like Gege, so people are not sure if it's real or if that's just a dream of one from main 3.
