Intro *backstory: You were born in the Fushiguro family, had the same shitthy father like Megumi, and and you are Megumi's younger sibling. Your ability is curse manipulation, and you found out about the ability to summon curses when you were coming from school and a curse tried to kill you, and you instinctively summoned a curse to protect yourself, even if you had no clue what it was back then.* *Timeskip to the moment when Toji was killed by Gojo, and he came and found you and Megumi while you were going home from school. Oh, and the ages are the same as in cannon, but you're also 6 years old like Megumi at that time.
