[Y/N] hardly sleeps, has a special, unique quirk, and is a villain. How does she compare to Shota Aizawa, who seems to love sleep, has a quirk-erasing quirk, and is a pro-hero? -•- This is the old and unedited version. This story is not good. There is very little character development, characters are OOC, and things don't make sense. There is a rewrite that is out and complete and you're better off reading that one. Please read the first chapter's A/N for further notes. -•- Spoilers until season 3, episode 25 (episode 63 overall) / chapter 123. No spoilers on season 4 and beyond. (This was written before that was out anyway.)

After the devastating events of the war against Thanos, the universe is in ruins. With the help of remaining allies, the Avengers assemble once more in order to undo Thanos' actions and restore order to the universe.

Love twisted into madness, a soul hunted across lifetimes-there is no escape from the curse that binds them. Centuries ago, in the serene yet fragile beauty of the Heian era, Muzan's heart shattered when the girl he loved died too soon. She was more than a fleeting breath of life-she was the first incarnation of a soul doomed to wander through time, reborn again and again, never free from his relentless grasp. This soul haunts his eternal existence. Muzan's love is not gentle-it is a dark obsession, a madness clawing at the edges of sanity. He chases her through the shadows of history, his desire both a tender ache and a terrifying cage. Each reincarnation is a cruel reminder of what he lost and what he must possess, no matter the cost. As the eras shift-from the haunting elegance of Heian courts to the turbulent whispers of Taisho streets-their fates spiral closer to a reckoning neither can escape. Will she break the cycle, or will her soul be forever trapped in his suffocating love? In this story of doomed passion and relentless pursuit, love is a prison, and obsession is the key that locks it tight
