Demon Slayer: I'll Mince Muzan for Shinobu's Sake

Haunted by the regrets of his past life, Hanyuu Hakukei awakens in a world where demons hunt humanity in the shadows. All he wanted was to cure his failing lungs—but fate had other plans. A chance rescue of two sisters from demon claws sets him on an irreversible path, forging bonds with those he never meant to protect. Now, driven by love and the ghosts of what he couldn't save before, Hakukei creates his own breathing technique and wages war against the demon menace. This time, he'll rewrite destiny—even if it means carving Muzan himself into pieces for the woman who stole his heart.
