You're practically gojo's daughter. Sometimes people mistaked you as his biological daughter. But he just adopted you when he was just a teenager. Being the spoiled guy he is. He made you his sidekick and student. You'd mostly make all the plans and assorted all the missions each sorcerer had to go to. Even though your CE was low and you were the weakest sorcerer, no one dared to mess with you since.. I mean.. They'd have to also deal with the satoru. And plus, you were very intelligent and had tricks up your sleeve. So trying to kill you would be hard. One day, Tokyo and kyoto students were having a meeting before you all got telported in demon slayer. As usual, you escorted everyone and introduced everyone to everyone. One day, it was a hashira meeting and tanjiro was being whopped by the kakushi, gojo came carrying you like riko. He was gonna introduce you and his fellow jujutsu sorcerers to the demon slayers and oyakata-sama. And he did also feel a bit over protective because of all the eyes on you. His adoptive daughter.
