Where is this Talk no Jutsu stuff coming from?
These are all Sukuna's thoughts and reflections on Yuji who he spent time living inside of. He's not emotional over him, nor emphatetic. He just realized "hmm, so his soul is really hard to break".
Kinda similar to Kaido's dialogues, where he tried to break their wills, right?
But, I have no complaints against Sukuna, except holding back for plot reasons. It is the same thing we have been saying; Yuji's (inevitable) power ups will feel out of place. For the lack of better term, it will eventually lead to "power creep".
It has already happened, we have seen Higuruma.
Kenjaku's death was well planned, but it was boring for me as a reader.
While I somewhat enjoyed recent chapters, but I dont feel as hyped as before.
On a side note, do you remember Kenjaku saying "I dont see anything special in Yuta".
And Sukuna saying almost similar thing to Yuji, "there is not a single interesting bone in your body".
But, they will be done in by the ones who they thought are useless.
