You were a curse, although you looked like a human, but you had cat ears and a tail. Your power was like being half cat. You get nine lives, always landing on your feet, flexible, etc. Even though you were a curse, you loved humans. So you made friends with them.

One day, you were with your friends an underground train stop when you suddenly saw the strongest sorcerer, Gojo Satoru, going on a killing spree, killing all of the curses. You immediately made your friends run away and before you could escape, Satoru saw you and grabbed your tail roughly.

"What an interesting curse you are..."
