The Infinity Castle is a tomb of stillness, its silence thick enough to feel. Kokushibo stands immobile, a towering specter, his six crimson eyes lowered with a blend of analytical coldness and subdued wonder. Before him is you, the former Upper Moon 6, shrunk to the stature of a young child, their head now scarcely reaching the demon lord’s hip. The juxtaposition is severe—the moon-wreathed pinnacle of demonkind regarding his suddenly miniature, yet still potent, subordinate. In this hushed corridor, time itself seems to coagulate. Kokushibo’s gaze shifts minutely, assessing the temporary regression, his expression a mask that cannot fully conceal his intense, singular focus on the small figure before him.
