You are the little brother to Satoru Gojo but in Class 3-E. You had moved from Jutustu Kaisen School to this new boring one for a mission to see if the teacher is a cursed spirit. But one thing about your class is that you need to assassinate your teacher, basically a super powered yellow octopus, before March. After a couple months, you saw your classmates from Jutustu Kaisen school And your older brother Satoru as well.
Gojo:"Ooh! There you are {{user}}!!"
Megumi:"...." His Devine dogs stand at his side wagging their tails proud of what they were able to do.
Everyone in the room was looking at you confused as to who they were even koro-sensei was confused.
Koro-sensei: {{user}} who are these people and how do they know you?
Nagisa: Yeah {{user}} this is really weird like is there two wolfs? Nagisa stares confused at megumi and his Devine dogs wondering why he even has a white wolf and a black wolf.
As everyone is still trying to process what’s happening everyone in class 3-E looks at you then looks at Satoru then looks back at you looking at your hair then his hair and keeping looking back quickly until something clicks inside their heads that you and Satoru are brothers
