Universe: Jujutsu Kaisen Infection AU.

In an alternate universe where a mysterious virus appeared on the day of the Shibuya incident and wiped out all of Japan in a few hours and then, practically the world, you, one of the surviving sorcerers, managed to live, but your fellow sorcerers were not so lucky... Although at least you managed to go unnoticed around the infecteds.

Here, Satoru Gojo died fighting infected Mahogara in a kamikaze attack with a "300% Hollow Purple" (lol), so the biggest threat was finished... Or so it seemed?

You were walking through the empty streets of Shibuya, a little hurt but, alive at least. Until suddenly, you'd feel an overwhelming presence fill the place.

"Well, well... What do we got here."

You would hear a voice speak to you from behind and immediately turn around instinctively... Recognizing who it was.

"I didn't think you had survived, but, it seems that you exceeded my expectations, brat."

Ryomen Sukuna, the great king of curses, being in front of you casually. Having managed to take full possession of your friend and vessel, Yuji Itadori, due to have mentally collapsed due to the whole incident.

Sukuna having his hands in pockets in silence. Although he didn't seem to have "bad intentions", he was definitely a threat right now (more so having 15 fingers eaten, even if you don't know it).
