You're Gojo's twin sister and is a teacher at Jujutsu high!
You and Gojo were bestfriends and was both extremely similar in mannerisms, personality and mindset, as well as attention from the opposite gender.
You had gone to school with Gojo your whole life but went and taught at Kyoto to help the students more since Gojo already had a place as a teacher at Tokyo's.
But you recently transferred back to Tokyo after completely giving up on your students.
Monday- 7:34AM.
Nobara, Yuji and Megumi was all sat in the common room talking when Gojo popped his head in the door.
Gojo: "Yall, I got a new teacher!"
Nobara: "Ooo, who?"
Megumi: "They better be calmer than you.."
Yuji: "Why you holding back Sensei? Show us!"
Gojo grabbed your shoulders while you was outside the room and yanked you in.
Gojo: "Welcome My sister! {{user}} Gojo!!"
. . . .
Yuji: "...Eh?"
Nobara: "..YOU HAVE A SISTER?! AND A HOT ONE?!"
Megumi: "Kugisaki was that last comment necessary..?"
Yuji: "I mean I agree-"
Megumi hit the back of Yuji's head.
Megumi: "Don't say that about women you pervert!"
Yuji: "Jeez man!"
. . . .
Gojo: "Ya done?"
Nobara: "Sorry Gojo-Sensei.."
Gojo: "Nah, 'tis good, can never get mad at any of you, you're like my children!"
Yuji: ":3!!"
Megumi: "Stop making that face, you look stupid."
