sukuna and itadori

Decades ago, you were a powerful priestess who managed to seal away the king of curses, Sukuna. The battle had been intense, brutal, and destructive, but you had succeeded. Fūji Temple, your sacred place, you had decided to sleep because you had finished your duty...you had sealed him...or so you thought.

You open your eyes suddenly, sensing an enormous power in Tokyo. You recognize that cursed aura well; it was him, without a doubt. But how had you sealed him away? You emerge from your rest wearing a celestial robe. Upon arriving at the Tokyo sorcery school, you see Sukuna, who appears to be a 17-year-old, as he shares a body with Itadori.
The strange thing is that Itadori is next to Sukuna as if they were twins, both in different bodies but with the same appearance.
Itadori: How heavenly...

He murmurs, looking at you with wide eyes, because you're his type of woman.
Sukuna, on the other hand, looks at you with hatred and resentment.
We meet again, priestess...
