Jujutsu Kaisen: Sukuna's Retirement in a Parallel World

Yuji Itadori can't stand Ryomen Sukuna, and Ryomen Sukuna can't stand him either. But since they share a body, the two can only grit their teeth and put up with each other. Everyone who knows them knows this, but the two of them refuse to admit it. Yuji Itadori: "That's not true! Instead of thinking Sukuna and I have a bad relationship, why not ask if we're actually super close?! That's what I call 'love' for him!" Ryomen Sukuna: "The brat's got it wrong. It's 'a friendship that lasts forever.' Don't let him mislead you~" That was the answer one of their friends got after risking their life to ask. Got it. So this is love, expressed by making each other sick. They both want to get away from each other, but neither can do anything about it. Then one day, while they were expressing their love for each other (by beating each other up), something worth celebrating by the whole world happened... It was so sudden. They both let their guard down and didn't dodge. In a glance, an instant, a single move, Sukuna went poof! In his place stood a cocky guy, right in front of Yuji Itadori, whose punch had yet to land. Yuji Itadori's first reaction to seeing this swaggering Sukuna was to punch him, then ask, "Who are you?" The guy, who'd just been unexpectedly punched, was just as baffled. "Huh?" Who was this Yuji Itadori who seemed to have punched him and was even cockier than he was? Meanwhile, in the Innate Domain of another world, the punch Ryomen Sukuna had thrown and couldn't pull back in time landed squarely on a certain Yuji's face. Yuji went flying, and then they both looked totally bewildered.jpg Yuji: ??? Ryomen Sukuna: ???? 1. This is a no-outline!!! brainchild. I like to let the story run wild, so there's plenty of wild OOC behavior and personal headcanons. It's very likely to go off the rails (it already has). 2. The Sukuna in this story is basically the Sukuna from a parallel world. 3. The parallel-world Sukuna has very little in common with the original-world Sukuna in terms of personality. He's practically a laid-back villain who just wants to retire. He also has a surname of my own creation that has nothing to do with the original anime, as well as a bunch of made-up connections with Yuji. Please take note!!!! 4. The story mostly follows everyday life (maybe). The original-world Sukuna probably won't return, and the parallel-world Yuji Itadori is also worlds apart from our Yuji in terms of personality. He doesn't know any of the Tokyo Jujutsu High students, except for Megumi, since Megumi is a child and there's an age gap. 5. Written at an elementary-school level. Please don't flame me if it's not your thing. Updates depend on the comments. Theme: Even I didn't expect it. The more I wrote, the more personal headcanons I added, and they now make up 80% of the story
