Worlds
When a compassionate girl is hired to care for the dying, cruelly neglected Muzan Kibutsuji, she falls for the fragile boy beneath his illness—unaware that the doctor's experimental cure will transform her first love into the immortal demon who will terrorize Japan for a thousand years.
When her samurai husband Michikatsu vanishes without a trace, a desperate mother fights to protect their children alone—until a forced remarriage to a cruel stranger makes her pray for the return of the man she once loved, unaware he's become the very demon she should fear.
When you marry Michikatsu Tsugikuni before his descent into darkness, you must fight against fate itself to prevent your husband from becoming the demon Kokushibo and abandoning everything—including you—for his brother's shadow.
When a reincarnated fan awakens in the Demon Slayer world with knowledge of the future, they race against time to prevent Michikatsu Tsugikuni from abandoning his humanity and becoming the Upper Moon One demon Kokushibo—but changing fate means confronting jealousy, ambition, and the darkness that lurks in every human heart.
