One thing that never made sense to me was the reasoning for Kenjaku sealing Sukuna inside Yuji. He is the only vessel that has complete autonomy of his body besides the angel, and even so, Angel decides not to suppress her vessel's conscience. Yuji unconsciously suppresses not only Sukuna's will but also his soul. This is important because how can Yuji even suppress someone like Sukuna? I mean think about it even Ogami; the curse user who brought back Toji was able to overwrite her grandson's soul with just the bodies information.

​

I also think it's interesting Sukuna found irony in Tengin keeping his body, and it's important to note Kenjaku had the majority of Sukuna's fingers and helped turn him into a cursed object, so it stands to reason Kenjaku had Sukuna's body at some point as he also knew of its location. I mean idk what motivations tengen would have to keep it. This also got me thinking there are two ways this can go:

Yuji is actually a piece of Sukuna as either he or Kenjaku somehow was able to divide his body both positive and negative. Yuji would still be sukuna but only the parts Sukuna would see as a weakness for him (love).

Or Yuji is a recreation of Sukuna's body before he discarded these things he believed were weakness as he ascended into this new form.

I still think Sukuna had a twin tho (that isn't Yuji), and this also leads to why Sukuna hates Yuji so much as well. Yuji reminds him of his brother whom he absorbed; this is the sort of twisted irony that both Kenajku and Gege love, and would also point out why Sukuna said Kenjaku does some creepy things. This makes it clear why Sukuna isn't surprised that Yuji resembles him, and is the reason he remarks that the brat is of that time. The time when he was just a sorcerer who had no choice but to rely on his inhuman strength; this can also give credence to Sukuna's and Yuji's actual cursed technique which I think is some sort of soul application.

Let me know if I'm cooking or sound insane.
