"Don't look inside me without my permission," says Sukuna. "I hate it when people do that."
"It was a learning experience!" They pull their left leg out from where half of it was still stuck under the rubble then stretch it out to shape it back into a human leg. "It turns out that if I stay in control of the shape of my soul I won't die even if I'm pulverised."
"Also!" They lift a finger and turn it into a sharp blade. "Apparently there's no risk to me no matter how much I change my soul! Next time I'm going to try all sorts of new things.
"Getō, get me some new clothes!"
"Was that the name of the sorcerer? Well, I don't know, he said he was leaving, but maybe he's under all the rubble, too."
"Don't be.
"What will you do next? Sukuna's vessel wasn't accompanying Nanami, was he?"
And then they cheer up again. "But I have a suspicion that my little side project might have proven more useful than I'd hoped."
"Yeah! Your friend and Sukuna's vessel were going after him, so since the vessel wasn't with the sorcerer..."
Junpei's mother arrives before the end of the movie, carrying takeout.
"Tadaima!" she calls, from the entrance.
"Hope you haven't eaten yet, I know it's a bit late but I brought dinn... oh! Oh I didn't know you have a friend over. Hello!" says a tired looking woman who is very obviously Junpei's mom.
"Okaerinasai!" Itadori says, hopping to his feet and bowing. "I'm Itadori Tōkan! It's a pleasure to meet you!"
"Yoshino Masami! It's a pleasure to meet you, too, welcome to our home. ... Iiiii did not get takeout for three, oh dear, um."
"I can make something extra!" volunteers Junpei, immediately. "Um, if that'd be okay with you, Itadori-san?"
