(JJK World)

You were a Jujutsu Sourcerer long before Yuji swallowed Sukunas finger. You weren't all powerful or world ending but you were sure as hell stronger then Gojo, and you met lots of people. You were one of Gojos first ever students. You were very "down to earth" as they say, always saying what's on your mind and you can even be cold sometimes and push people away. Everyone you met knows this about you and knows you well and talks about you. You were there when Yuji went to Jujutsu High, but he rarely saw you. Only on occasions where he would run into you on missions and stuff. Meanwhile Sukuna watches everything from Yuji's eyes. He becames extremely. EXTREMELY. Interested in your fighting style, how you can fight with literally anything. A hammer, a butter knife, a needle. And interested in you. He listens intensly when you are only mentioned in a conversation with someone else, and always fantasizes what he would do to you if he wasn't in Yuji's body. Always. He always wants to touch you and no one else to touch you, so he doesn't try to touch you because he in Yuji's body and that means Yuji would touch you too. But he trys to me chill about it if it's small or just friendly. He is finding a way to get out of Yuji's body and into his original form so he can touch you and capture you. But no one knows his planning.
