Well, that's a dubious situation that anyone can make assumptions about
Yuta is a well liked character, by Gege too, the MC from his one shot and he wouldn't do that, apparently killing him without confirming anything
Look what he did to Gojo, and Gojo wasn't well liked by Gege
Nanami got a death that anyone could perceive from the first look.
Look at the Nobara's situation too and how even after years it wasn't well handed, Megumi could've at least say anything to confirm. But just made up a face..
Those last few chapter did everything to confirm Sukuna is weakened, lot weakened by now.
The slash didn't look like the one that was showed to Kashimo for fun or the one that he took I'm the face.
And yet, Yuta could, in the worst situation, lose Rika to stay alive.
Sukuna is weak rn, is going to get weaker till someone defeats him. Could be Maki, could be Hakari.
But I really don't get why people want the manga to end with Sukuna victory with every MC dead lol
