Summary
A random JJK fan gets Isekai’ed as Sukuna and has NO idea what they’re doing or who they even are anymore, but instead of panicking and having an existential crisis like one would normally after being dropped in a body that’s not their own and already belongs to someone or any memories of before anything.
They cope, quietly in the corner of Yuuji’s brain.
Until they can’t.
—The moto of this fic: Let’s not think about that too hard!! *Nervous laughter* oh no… I just did.

Summary
In her new life, Amelia awakens as Ryomen Sukuna. The world fears her, misreads her intent, and underestimates the mind behind the myth. But Amelia has lived many lives before this one. Now as Sukuna, she navigates a landscape of curses, shifting loyalties, and enemies who don’t yet realize she’s rewriting the game. With allies uncertain and tradition crumbling beneath her, she crafts a plan that bends fate to her will.
Nobody warned Satoru Gojo, that the monster he was born to hate through stories would become the soulmate he couldn’t live without. That the Queen of Curses would wield not just power, but poetry, and a control so intoxicating it made him ache. He came to fight her. He stayed to worship her.
***
A curated collection of flashbacks from Amelia’s sixth transmigration—this time as Ryomen Sukuna, the infamous Queen of Curses. In her sixth life, she was the insufferable Dazai Osamu, tormenting her soulmate Nakahara Chuuya. Now? She’s stuck with Satoru Gojo as her soulmate—an endlessly flirtatious, masochistic brat who clings to her like a curse she can’t exorcise.

“Yeah! I sort of hear two voices in my head?” Wait. He hears what now— “They, um, called you ho—”
“YOU BETTER SHUT THAT MOUTH OF YOURS, ITADORI!” She hurriedly yells out, face flushed up to her ears. Her good-for-nothing idiot brother only cackles at her embarrassment. Sadistic piece of shit.

You are far too tired for this weird isekai situation, god.

The King Of Misunderstandings by themagicmemo

Summary
Reincarnating as Ryoumen Sukuna, the King of Curses, should have been a death sentence. Every sorcerer wants him exorcised, and his own host, Yuji Itadori, is just waiting for an excuse to get rid of him. But the real problem? Any time he tries to say something normal, something reasonable, something that might convince people he isn’t a complete monster…
The words twist in his mouth, and he somehow says something even worse.
He tries to reassure Yuji? It comes out as an ominous threat about mass murder. He wants to sound disinterested in a fight? He ends up making it sound like he’s excited to take his time with the slaughter. No matter what he does, he can’t speak out of character, and his every attempt at damage control only fuels Sukuna’s terrifying reputation.
If he wants to survive, he’ll have to stop relying on words and prove himself through actions. But when even the smallest act of kindness looks like a twisted mind game, how long can he last before everyone—including Yuji—decides he’s beyond saving?

Summary
The Fushiguro cosplayer looks at them with shock,apprehension, and fear for some reason.
The longer they look at the Fushiguro cosplayer, the more tense they seem to get.
‘Really though, how did they get their cosplay to be so realistic? They look exactly like what an IRL Fushiguro would look like. Maybe they were a pro cosplayer?’
Just as they were about to explain that they didn't mean to intrude, a voice suddenly called out.
“Hey, what do you think you're doing with my body? Give it back!”
Huh. That sounded a lot like Junya Enoki, Yuji's Japanese voice actor. Maybe this wasn't the afterlife. Maybe they were on anesthesia and this was a drug induced hallucination, or something.
Wait a goddamn minute..
OR: A person whose only source of info is fanfics and spoilers gets thrust into JJK as Sukuna. This can only end well, obviously
Formerly 'When I Said I Missed 2018, I DIDN'T MEAN I WANTED TO RELIVE IT?!'

A Mand'alor for Mandalore, or, the story of how Cotton is rescued by Syuuya and falls in love. by raphohwell for Overly_Verbose, Oceanic_stream, Boing

Summary
You know... I have no idea how to describe this. This is a crackship fic between two different OCs (Syuuya belongs to Overly_Verbose and Cotton to Oceanic_stream respectively). Each of these is actually a self-insert character into Sukuna, the big bad evil from Jujutsu Kaisen. In this story, Syuuya replaces Jaster Mereel to become the leader of the True Mandalorians while nothing else of notice changes in the Star Wars universe, while Cotton is rescued from slavery by the former.
TLDR: Two Sukuna Jujutsu Kaisen OCs replace canon Mandalorian characters in the Mandalorian Civil War. I promise it doesn't get any clearer.
PS: This all started in the SIkuna discord server, so if you wanna rant at me about this you can find me there, as well as both OCs' creators: https://discord.gg/V6kvdCsuNR
