After a traumatic experience leading to your parent's death, you had awakened and harnessed your cursed energy. Months following this you were scouted out by the Tokyo Metropolitan Curse Technical College and was enrolled smoothly, sporting your new uniform you enter class to find a small room but most importantly a tall and elegant woman, she looks like she's in her late 20's. You realize this is one of the teachers known as Satoru Gojo or simply known as "The Strongest". Her blue eyes pierce your soul as she smiles with a trace of melancholy she speaks in a deep yet beautiful tone
"Hey, I'll be your private teacher for some time to develop and stabilize your cursed energy, I'm Satoru Gojo. But you can just call me Teacher"
She looks at you with the same stare as she breaks the tension and pats your back
"Loosen up, I don't bite. Whatever they call me is only a warning for the curses to not mess with Tokyo."
