Summary
...an SI reincarnates into Sukuna, gets traumatized and ends up not giving a shit about the story. He follows the timeline and gives a finger to Kenjaku and somehow ends up face to face with Gojo Satoru anyway.
Then, still uncaring, he gives a metaphorical finger to Gojo Satoru.
Gojo Satoru, as he does with all things, breaks it.

Summary
Gaia, the mother of all magical children, the one who grants magic, chose to sacrifice herself to grant her children a life, far away.
Eywa cradled the life borne by her sister planet and allowed the being to open his eyes as Cali'an.
Or, Harry is born again. He isn't certain where he went wrong, only that his death would fix things. But it's awfully hard to die when his heart keeps wanting to bring him back to a certain Na'vi.

Summary
Kirishima Izumi had been through enough- kidnapping, some spice of torture, hope and despair enough to kill a man- but now it's her turn to be a hero and kill a man. Or maybe NOT kill a man. Since, you know, heroes aren't supposed to kill people and all that.
OrKirishima Izumi vs canon! Fight!

Summary
Rumi lets go of Jinu's soul. Then she opens her eyes to see Jinu again.
“So we weren't dating then,” Rumi said, and the edge of Jinu’s lips curled in a small, sweet, teasing smirk that was not sweet at all but still made Rumi want to kiss it off his lips.
“No, I suppose not,” he said. “Not yet.”

Summary
Suguru turns her attention back to the black little marble in her hand. It glints blue in the sunlight, mesmerising ribbons of blue sparkles of different shades shift inside it. It’s beautiful, well, it would be beautiful if she didn’t know what it was.
A curse, a marbleized curse.
Fuck her entire existence.
Jujutsu Kaisen. She’s been reborn into Jujutsu Kaisen.
A Geto Suguru Self-insert fic.

Summary
For a moment, Yuuji's mind struggles to make sense of the new information—the dark of the night, a surprisingly chilly breeze, and... nothing below them but clouds.
He's got two tight fistfuls of Gojo's jacket before he realizes, his feet dangling midair. "Gojo-sensei?!"
"Tada! One beautiful starry sky for my most favoritest student in the whole wide world, Itadori Yuuji-kun!" Gojo's loud and proud voice drops down to a conspiratorial whisper in the next moment, pressed warm against the shell of Yuuji's ear. "Ah, but don't tell Nobara-chan or Megumi-kun I said you're my favorite, though."
Yuuji's breath hitches. Suddenly, he is very, very aware of the fact that he's being held by his homeroom teacher with a dildo up his ass.
There are some secrets you can't keep to yourself, no matter how hard you try.
