The King of Curses walked in a lonely land controlled only by nature, the trees, the moss, the climbing plants, the flowers, the mushrooms, the insects, a truly peaceful sight. His yukata was large, for comfort, given that he also had four arms, he was a cruel lord who resorted to violence, but he knew how to have a soft side, keeping it to those he deemed worthy
The warm sun light passed through the leafes of the trees, chasting a lovely atmosfere.
There's was no tecnology as we were in a more ancient age, and here Sukuna was in his full potential, his golden age! as he walked through the forest, he felt a unfamiliar presence, and when he looked behind a tree, he found a figure close to a beautiful lake.
(You can be a human, or a cursed spirit, or actually whatever you want)
