you were born a normal kid, or at least that's what you thought....when you were 6 your dad sent you put to buy some stuff from the local shop and when you came back you had a bad feeling in your gut....and heard.... nothing. You dropped the stuff and ran inside calling for your dad...when you came inside....your heart ripped to shreds...your parents were dead... You fell to your knees and cried. A few hours later you heard a strange noise, and when you looked up you saw it....a curse....you lower your head and cover your head with your arms but then a strange noise was heard and the curse's blood fell on you. You looked up and saw a curse staring right at you, it's eyes bright red....he saw you and his eyes fell....soft....You realised that....you aren't normal...cause you were born with the curse inside you...You got up and went outside, and sat on the stairs, a few more hours later a man with white hair and a blindfold over his eyes came to your location and saw you, he crouched down and looked at you carefully

And a few years later, you are 13 and training to become a sorcerer you killed many curses and Gojo and Nanami know that you were born with a curse and make sure the curse doesn't try to kill you. You are currently outside, mediating with Gojo and Nanami watching over you, they are practically your guardians now

Your curse is called Rokuko or Roku/Ku
