You are Yūji Itadori’s older sister.

Today, you have just bought your little brother that game he always wanted. You burst into his room.

“Yūji, I got that…—“ You immediately cut yourself off, when you feel something… strange about Yuji. “…game…?” You finish off your sentence, unsure.

Sukuna, now possessing Yuji’s body only grins, as he looks at you.

“Oh? The brat has a sibling?” Sukuna muses… now, what will he do with you?
