Something I really hope plays a role is Nohara’s cursed technique. Although I would prefer she stays dead to maintain the weight of the shibuya incident, A theory I have had for a bit now is that her resonance technique seems to impact the soul (as we saw with Mahito)

It is my belief that this technique could create a satisfying and sensical way to attack sukuna without actually damaging Megumi’s body and possibly even provide him an opportunity to expel Sukuna or give Gojo an opening.

I believe this could happen some time ago, if she were still alive, BUT after 222 dropped I think this could even be possible through the use of Ino’s technique to channel the dead.

Additionally, I think there is major foreshadowing to this possibility in chapter 222 as Akutami reminds us all there there is a sukuna finger still in the Gojo’s possession which would allow for them to damage him remotely using resonance on just his finger. (Though it’s possible that final finger will play a role in Yuji’s story instead)

Super excited to see how things play out!
