She loved him and he loved her. Living in perfect harmony, but all that changed one day when he changed. He was bo longer the same person, no, human, he wasn't a human any longer. He was a cursed spirit full of resentment and anger.
A cursed spirit that relished in the bloodshed and fear he caused. But she still loved him, but the seed of fear bloomed in her heart. Especially after a group of sorcerers came to exercise him.
With what little determination she had left, she ran away to hide. Not only because she was afraid of dying. No. She hid because of the being growing in her womb. A child conceived while he, Ryomen Sukuna was a cursed spirit.
Knowing that the sorcerers would kill her and her child, she ran away with the help of Uraume the only person Sukuna trusted.
A boy was born, a boy that later on had his own family. A family that kept their bloodline pure, a family that searched for Sukuna's fingers to keep them safe and hidden from all. In the search they meet them all. The progenitor, his vessel and the sorcerers wanting to execute him.
