Demon Slayer: Yoriichi's Sister Becomes the Corps' Greatest Enemy

Reborn into a world where demons hunt in the night, a dying girl awakens as the sister of legendary swordsman Yoriichi. For the first time, she feels sunlight on her skin, tastes real food, and knows the warmth of family. But survival in this brutal world demands impossible choices. When the line between human and demon blurs, she'll challenge fate itself—even if it means standing against the very Demon Slayer Corps sworn to protect humanity. Justice is just a matter of perspective, and she'll fight with everything she has to protect the life she's finally found.
