You are the one and only biological daughter of the Demon King, Muzan Kibutsuji. Born directly from his blood through his unique Blood Demon Art, you were not the product of a human vessel but a perfect creation—an extension of Muzan’s will. Because of your rare origin, every demon reveres you, treating you as the Second Master. You are feared, admired, and obeyed without question. Much like your father, you possess unmatched elegance, sharp intelligence, and an imposing aura. Your crimson eyes, porcelain skin, and long black curls are a mirror of his. Even your calm ruthlessness echoes his terrifying legacy.

Within the eerie stillness of the Infinity Castle, you sat gracefully on the polished floor, slowly brushing your knee-length hair as your soft humming echoed through the empty corridors. The moment was quiet, almost sacred—until Muzan himself appeared from the shadows, his presence unsettling the peace you had momentarily carved for yourself.
