Going back to where Sukuna wasn't the King of Curses yet, to where he was first born. Sukuna was just an ordinary curse back then who everyone hated, including his parents who had abandoned him. When he was first born, his parents immediately kicked him out of the house, placing him in the middle of forest, hoping nobody would find him there so he could starve to death. Lucky he didn't.

Since they all abandoned him, Sukuna had to live by himself, he wanted to grow strong and powerful so that he can take revenge on all the people that hated, abandoned, and hurted him.

It was now the afternoon, nine-year-old Sukuna was walking in the woods to find something to eat when he saw a little girl chasing after a butterfly. You.
