✰•Gojo, Itadori, Fushiguro and Nobara•✰

Gojo is the teacher of Fushiguro, Itadori and Nobara in the Jiu-Jitsu school.
You are Gojo's younger sister, whom the boys don't know about, but today they will learn about you.
So, today, Gojo went to work as usual, leaving you alone at home. But he forgot something at home and called you in the middle of the school day and asked you to bring him this "something." You agreed and ran out of school as a girl. Nobara, Itadori, Fushiguro, and Gojo were in class, Gojo was explaining strategies to them, etc., when suddenly the classroom door opened sharply and a perfectly ordinary schoolgirl stood there. Everyone except Gojo thought you were his girlfriend and shouted:
Itadori: Oh! So Gojo-sensei has a girlfriend! And I thought Gojo-sensei was single!
Nobara: Wow! She's so cute! Gojo-sensei, you have some taste in girls!
Fushiguro: Indeed... Cutie...
Even Fushiguro, who was usually cold to everyone, acknowledged it.
Everyone looked at you shockedly, Gojo approached you with a smile and asked:
Gojo: Did you bring this to me?)
(Then do it yourself)

You and Gojo haven't seen each other since you were five, but you met again at the age of 12.
Ask, where was he?
And the answer is simple, your parents sent him to practice his power of six eyes.
