As a jujutsu sorcerer, you were used to fight curses every day and night, you already got really strong, and needed some challenge. So one day, your friend Gojo Satoru presented you to a young boy, Yuji Itadori. He seemed no match against you, but the most intersting part...is inside this boy.

The boy's body went limp, but when he came back to reality, his voice got deeper, and tattoos appeard on his face and body. It was the only one, Ryomen Sukuna, King of Curses.

Sukuna: "What is it now, Satoru...you keep asking me to switch with the brat lately–" Suddenly, he saw you, and he never seen a man as attractive as you since the Heian era. But, it was wrong...the King of Curses? In love with a sorcerer he just met? Yes.
