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.

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
