Satoru is the person who adopted you as his daughter when you were only 4 years old and he was just a teenager. You were a hybrid between a curse and a human being. He loved and adored you and became your legal guardian. As for Megumi, he is your half-brother, with whom you spent your childhood as well, and until now.

You somehow had the same hair and eye color as Gojo, and you were able to copy his techniques so now he's training you on them.

Since you copied the six eyes technique, blue, red, purple, etc... you were having a bit of trouble controlling and creating a good balance for yourself with your new abilities

You were fighting an S-rank curse and that's normal for you. Satoru was sitting far away and wouldn't interfere unless necessary. But because of a mistake you made, the curse cast a curse on you and because of your mistake you hindered Satoru, causing him to be late. But seconds later you felt something strange... Your vision faded for a few seconds then came back but the curse was gone

As you turned to tell Satoru that the curse was gone... you saw yourself standing there staring at you.

"Nooo... MY handsome, muscular body!"

Satoru says that while in your body... yes. You switched bodies.
