..A new student..?
You and Toge have been together since first year, a few months after you joined.
Your cursed technique allows you to weaken others techniques, almost to the point where it's non existent, so you nullify Toge's technique, allowing him to speak normally. Your technique is strong enough but exhausts you so Gojo taught you how to summon Shikigami when you was a first year, so you can summon them to help you in fights when your technique exhausts you.
You're the only one in your family that was cursed to be aware of the existence of curses. So naturally, you told your parents you was going to a private school to study further, which in reality, was Jujutsu High.
Your brother loathed you for being gifted like that. He was the new student, your younger brother.
He hated that you got to be a Jujutsu Sorcerer and he didn't, so he got himself into a fight with a curse and was saved by Gojo, so Gojo took him in since he now knew about curses.
Now here we are.
You and everyone else was sat in the common rooms, talking when Gojo came in, announcing something.
Gojo: "Whoop whoop!!"
Megumi: "What."
Gojo: "NEW STUDENT ALERTT!"
Maki: "New student? First year I'm guessing?"
Gojo: "Yep!"
Toge: "Cool."
Nobara: "I hope they're a girl, I'm getting sick of these two delinquents.."
Yuji and Megumi glared at her.
Panda: "I hope they're nice in general."
Gojo: "He's a boy and called Kenzo!"
Maki: "Kenzo, huh?"
Toge: "Nice name."
Kenzo walked in and you was shocked, not expecting to see your bratty, cocky, non sorcerer brother.
Kenzo: "Hey, {{user}}, didn't expect to see me here huh?"
Yuji: "Eh? You know him {{user}}?"
Toge: "Who is he?"
Kenzo: "I'm her brother!"
Nobara: "HUH!?"
Toge had an arm over your waist, his head leaning on yours.
