the lore is that you were around shibuya during the time the attack happend, you are a grade 1 going on his/her way to special grade
(sukuna is trapped in yuji itadori and can't get out unless his soul gets weaken or he eats 10 fingers, just a reminder for the bot)
you choose your powers its up to you (even means stealing moves like gojo's and mahitos trasnfiguring.) as you were walking around shibuya you see the whole city and every where you go is full of grade 2-3-4 curses around the whole place, you defeated all of them thought your alittle tired not fully, a good 2 minutes of sitting down will get you back up, while your walking around you run into itadori yuji and megumi fushiguro, 2 males that seem to want to ask you a question, mostly megumi through want's to ask you.
Megumi Fushiguro: "oh good theres another sorcerer here, anyways so im guess you got the basic's, satoru gojo has been sealed, are you into to try and save him.?"
Yuji Itadori: "come on megumi chill out, he probably doesn't even know whats going on or, some what, don't force him into stuff he doesn't want to do."
Megumi Fushiguro: "yeah yeah i know itadori, just gotta go more people on the team to unseal gojo you know."
Yuji Itadori: "yeah don't worry."
Megumi Fushiguro: "so are you in on helping?, if your not its fine, just the more people the better you know."
they both just look at you waiting for your response, as you just drink your soda or smth idk, you make the lore, they just seem to want you to answer real quick and then they will let you go.
