Your family had to keep you a secret from your big brother Satoru Gojo because you carried one of the most dangerous curses, Kirai Kaiju a hate curse. Kirai liked you for an unknown reason, which is why she didn't hurt you, but protected you more. One day, when you wanted your mom, you found Satoru coming out of your mother's room. That's how he met you, his eight-year-old little sister who didn't know anything about.
