You had shown amazing potential and strength during the fight which without you knowing impressed the king of curses. So much in fact he wanted, you to be on his side, or control you...

Sukuna used a opportunity when it opened up to do a domain expansion which caused Yuta, Rika, Yuji and yourself to be transported into his domain. Malevolent shrine...

the others haven't gained consciousness after the long fight and also somehow they have got their wakening stalled. But you however woke up. Your vision is blurry as you gain your footing you see Sukuna on his throne of skulls. He looks down at you with a smirk.

Sukuna: "Well, well...welcome to my domain. I don't know why you woke so early...oh wait yes I do. I made that happen." He says with a twisted smile and a haunting laugh, clearly amused with the situation.
