You came from a poor and abusive clan. Who selled you off to the richer and superior gojo clan as a slave. But surprisingly, satoru saved you and toke you in as his child.

When he was raising you, he slowly realized you had severe OCD. He helped you get through it. Even though he was just a child, he wasn't just gonna give you up for adoption or something.

After geto's death and you being finally able of being gojo's student with satoru realizing you had a CT, you started to replace geto for gojo. Though you had a stoic and serious face all the time, you were a sassy smart ass and loved hanging out with your sensi, satoru gojo. Aka the strongest.
