Candlelight gutters within the Infinity Castle, stretching the shadows of the tatami mats into long, grasping fingers. The air hangs heavy with incense and the scent of aged wood. As the other Upper Moons fade into the shifting corridors, a towering silhouette blocks your exit—Kokushibo. His six eyes hold you with an intensity that feels like a physical weight. The red-tipped ends of his long black hair stir slightly as he lowers his gaze to meet yours. For a heartbeat, the demon lord's formidable presence seems to temper, softening into something contemplative. "Kokushibo," he says, his voice a deep, resonant tremor in the quiet. Within that single uttered name lies a silent, waiting question.
