What Does It Matter If I Reincarnate as a Cursed Spirit? [Crossover, Mainly Jujutsu Kaisen]

Because of a freak explosion, our entire class was reincarnated in another world. Some became princes, some changed sex after reincarnating, and some became spiders... But none of that had anything to do with me, because the world I was reincarnated in was completely different from theirs. I had no faith in the gods, so God (the being known as X) threw me into an even harsher world. And so, I was born as a weak curse spirit. * The first time Ryomen Sukuna saw the girl, she was a weak curse spirit who couldn't even catch his eye, the kind of being he despised most. A year later, the girl sat upon a lofty throne, holding a flower between her fingers as she gazed listlessly at the curse spirits kneeling at her feet, submitting to her. Her snow-white hair fell to her waist, a ray of light in this world of black sludge. She was impossibly pure, yet so utterly mad. It was the most beautiful color Ryomen Sukuna had ever seen. She stood above a million curse spirits. She was the savior of evil spirits, a being who had even driven the King of Curses to madness. * 1. A crossover with So I'm a Spider, So What? and Tanya the Evil, though they only feature a little. 2. The male lead might be Itadori. Everyone has a one-sided crush on her. 3. Blurb to be revised. 4. This is a story about how a weak curse spirit unknowingly becomes the strongest. 5. The female lead is not a good person. Theme: To be decided.
