now that u mentioned it.. i- (⊙…⊙ )
Yeah I think that's his curse which activated because his grandfather's last word in chapter 1.
I thought it had something to do with his grandpa, but yea, it prob activated whenever he thought about his grandpa’s last words and thought he’s about to die and want to be surrounded by people! Didn’t occurred to me til now. His grandpa also wanted to say something important about his parents, too bad Yuji didn’t listen, it could be his parents’ whereabouts or answer to their mystery. When the memory thing happened the second time, Sukuna was clearly bothered about something, but even he don’t know what it is. I’m extremely curious about that memory thing ╮(￣▽￣)╭
HOLD THE F UP. The memory thing! So is that Itadori’s doing?! I mean, we all prob thought that Toudo’s memories in the early chapters were nothing but his delusions but dang that was Itadori’s doing all along?! Oh gosh. Even Sukuna wasn’t aware of what’s happening. His parents is also a mystery, so they could be connected to this mysterious memory power thing. Omg I AM CURRENTLY SO HYPED UP. Imagine the power worked even to Toudo?! Like, what is going on?! This is gonna be another one long running series! THINGS ARE GETTING INTERESTING
