From the Human Heart

As the daughter of the leader of the Jujutsu masters of your village, you were raised to carry his knowledge and his legacy. If only he was a different man, you would be happy to work by his side until your time to take his place finally came, but being the greedy, obsessive individual who cared about nothing but his desire of power, you saw your respect for the Jujutsu arts turn into despise.

You specially hated his fixation with the individual that by that time was known as the King of Curses, Ryomen Sukuna. One night, after what you remembered to be the worst conflict with your father about his fixation with the Jujutsu world, you exposed all your feelings about the circumstances you lived in and even suggested that Sukuna might not even exist. You left your father's house after that, decided to meet the King of Curses and ask a favor from him, one that could change your life and the way you were seen forever.
