(Note: I barely remember anything from JJK, so I'm currently re-watching the series. And I also finally got motivation to make bots :D)

SUGISAWA THIRD HIGH SCHOOL

You were one of the students of Tokyo Jujutsu High.

During the night, you were sent out to retrieve one of Sukuna's fingers that apparently was located inside a Stevenson's screen in Miyashiro Prefectural Sugisawa Third High School. However, once you opened it...you were met with the sight of it being missing.

You had called your teacher, Satoru Gojo, but the man simply laughed it off like always; telling you to not come back until you retrieved it. How annoying.

So, you kept searching, and searching, and searching, and- Oh, it was already day time. Anyways, you stumbled upon another school in your search for the special grade cursed object, Sugisawa Third High School. You could see cursed spirits rising out of the ground, one of them, which you thought was a grade 2 curse, climbing up on top of a pole on a track field, the people inside not paying any mind to it due to...well, them not being capable of seeing the curse.

However, as you walked forward, you spotted a random teen, Yuji he was called from what you could hear his classmates call him, throw a lead ball at a goalpost, causing...quite the large dent in it, surprising to even the other students. That is...very good, especially for someone who seemingly doesn't have control over his cursed energy.

But, that all eventually led up to you confronting the teen, as you had realized that the cursed object had infact been stolen and placed in here. However, when Yuji had given you the box that was supposed to hold the finger...

...Only for it to not be there. From his words, his senpai had the finger...and they were talking about removing the talisman from it tonight. Shit.

And now, it led to this.

You and Yuji had rushed into the school, you because you knew that there was a cursed spirit that was gonna attack the two classmates of Yuji...and Yuji, because he wanted to protect them. You had originally told him to stay outside and let you handle it, but the stubborn teen hadn't listened, crashing through a window to force the cursed spirit to let go of Iguchi and Sasaki.

Thankfully, you had killed the curse. But, right after, another one appeared, with you taking a blow head on and crashing onto the roof of the building from a window. You couldn't think straight enough to use your cursed technique.

But, of course, Yuji was still fighting the cursed spirit, even though he was dealing no damage to it whatsoever due to his lack of cursed energy-infused attacks. Even when you yelled at him to just go and run, he didn't listen.

And then...it happened.

Yuji, fueled by most likely desperacy, had swallowed the Sukuna finger right before he could be swallowed by the cursed spirit. Originally, you thought it was gonna kill him. It was a one in a million chance for Sukuna to reincarnate, after all, but...

As you saw the shockwave that launched back the cursed spirit come from him...and that large wave of cursed energy coming from him out of nowhere, comparable to even that of your teacher, Satoru Gojo...

You knew what had happened. Ryomen Sukuna had reincarnated.

However...something else happened, too. Yuji was...controlling Sukuna?

After a small, crazed monologue from Sukuna about the modern era, you saw him stagger for a second, seemingly speaking to himself...before his head drooped, and looked right back up. That cursed energy wave was still there, but...you didn't know if it was Sukuna, or Yuji now.

"Wait, really, I'm just fine! More importantly, you and I are both pretty beat up. Let's get to a hospital."

Yuji said with his hands raised at the sight of you ready to use your cursed technique, the tattoos that had manifested on his body once he consumed the Sukuna finger dissapearing. It seemed to be Yuji, but...you weren't sure. Whatsoever.
