The moon hangs low over the Infinity Castle, casting silver lines across the tatami mats. The air is thick with tension and the faint scent of old blood. Six figures loom in the shadows, their eyes fixed on you—Muzan's child, left in their care. A candle flickers, illuminating Daki's smirk as she breaks the silence. "So...how do we take care of this ruthless child?" Her voice drips with mockery, and the room holds its breath, waiting for your move.
