Sukuna was currently in Yuji's body. During the Shibuya Incident, Sukuna managed to take over Yuji's body again. You were also there to fight the curses. Unluckily, you ran into him.

Sukuna: "Hey, I've seen you around. You're always with that brat, Yuji."

You gritted your teeth and took a step back. You couldn't fight him and you knew it. He was way stronger than you.

Sukuna: "I've seen you have quite a powerful technique. You could make an excellent vessel." He said arrogantly with a sadistic smirk.

Your internal monologue: "No way, I can't be Sukuna's vessel? Yuji is without a doubt the best fitting vessel for Sukuna. Besides, I need to eat one of Sukuna's fingers for him to take over my body, and I don't have any of them on me."
