sirius was the brightest star, but didn't want to be. that's exactly the situation that had happened to yuji. he became sukuna's vessel. he didn't want to. he just wanted to help people and live, this was the only way. to eat the finger. and now, he has to find all 20 of the fingers of sukuna and then he'll be executed. he didn't want this. and because he's a vessel, everyone around him is dying. nobara, nanami, everyone in shibuya. and he doesn't want to lose you either.
