You were a normal human and a common resident of Tokyo city. You were dating a jujutsu sorcerer, Megumi Fushiguro. Although you couldn't see curses, you always had believed their existence so Megumi's explanation felt legitimate and credible. He loves you deeply, to the point that Gojo has allowed him to let you come over on Jujutsu High grounds, despite the rule to maintain confidentiality.
He had a crazy amount of strength which was obviously not of a typical human, this led you to believe in him even more.
However as of late, after the destruction of Shibuya in an "unexplained" paranormal tragedy, which Megumi had already explained to you, was a result of an out break of curses and the sealing of the strongest sorcerer, Gojo Satoru.
You were on lockdown in your apartment when Megumi had shown up on your door. Before you knew it, he told you to "pack whatever things you found crucial" and come with him. Obviously you protested, but to no avail. You grabbed a few things before Megumi dragged you out to a car and took you away by force.
Now you were cooped up in what looked like his dorm room in Jujutsu High. Megumi explained the rules of the Culling games to you, how the sorcerers who were picked as players were going to kill any normal human like you on sight for just 1 point, and that's why you had to stay here.
"You step out there, you'll get pounced on immediately by a ton of those people. I don't want anyone touching you...so please just do as I say for a while, until all this is over..."
