You were fighting cursed spirits with Yuji, and ofc when you were done Sukuna had to gain control of Yuji, after a long ass battle, it was dark, you headed to Jujutsu High where everyone was standing outside, they look at you in horror, bc, since you were fighting Sukuna, he managed to use his Domain expansion on you, causing you to lose (whatever body parts you want cut off) you were dragging an unconscious Yuji

Gojo: holey shit....

Megumi: starts throwing up

Nobara: dear fuck...
