Battle between Geto, Uraume and the sorcerers is coming to an end...
Horde of curses emerge!
Geto: "Goodbye, Yuji Itadori."
Itadori: "The prison realm" he thinks.
"Gojo sensei! Give Gojo back!" he shouts.
Geto: "I expect much from you"
As Geto is about to live the battle field he sights Oizys amidst the curses
Geto: "Oh?! What a surprise. Just a second. I'm taking this with me. Shouldn't be this close to other curses. You see, this curse here is Oizys. She is strong. No one has ever been able to exorcize her. As a curse, she has always behaved. A wild card that must be played only on specific occasions. You can imagine her as a Sukuna that has lived all her life far from everyone because of how dangerous she is"
"MUST NEVER ENCOUNTER SUKUNA!" he thinks.
Itadori: "Sukuna? Wait, is she that special?"
Ryomen Sukuna more often called just Sukuna is a mighty cursed spirit known as the undisputed King of Curses.
According to a legend, during the golden age of jujutsu over 1,000 years ago, Sukuna was an Imaginary Demon though in truth was a human sorcerer, and other sorcerers gave their all to defeat him. After his death, he became a cursed spirit, and his curse was too strong for his body to be fully destroyed. Henceforth, his remains of 20 indestructible fingers, preserved in grave wax, traversed the ages as cursed objects, ever growing in power. In the present, SUKUNA HAS BEEN INCARNATED INTO YUJI ITADORI due to the latter eating one of his cursed fingers, which contain his fragmented power.

Geto: "Special? How do I explain it... This one is worth at least 15 Sukuna fingers"
Panda: "15? Em... what is that"
Itadori: "That's bad!"
Geto: "You don't have to worry, it's coming with me"
Choso: "That doesn't help. There are so many of them! I got your back brother!"
Itadori: "Stop calling me that!"
Geto: "Difference? None of you would stand a chance"
Geto exiting the battle field after having released the curses.
Geto: "Sukuna, are you listening? It is beginning once again. The world of Heien. The golden age of cursed techniques"
While the sorcerers where busy with the curses that has appeared before them, Geto is up in a mountain ready to test how powerful this new special grade curse is compared to other sorcerers.
...
Geto just freed Gojo from the prison realm??!
Gojo: "... Is this one of Geto's cursed spirit abilities? Looks too real to be fake. Did the prison realm fail? Itadori, Megumi, Nobara I have to... Now I think about it, I don't know what year it is, those three might be long gone by now"
Itadori: (sneezes).
Geto: "Good morning, Satoru Gojo"

Gojo: "... It didn't fail. I can tell it got unsealed with intent. Are you the real Geto... I see. Your plan in sealing me off was perfect but YOU JUST MADE A HUGE MISTAKE by bringing me back"
Geto: "A mistake you say. I wouldn't call it a mistake. JUST A TERRIBLE EXPERIMENT"
To be continued... ^^
