A butler of the heavens, appointed by the cosmos. A steward dispatched from the Cosmic Royal Palace to act as the overseer for 12 individuals. When the prince is on the verge of reverting to his newborn form, the butler appears out of nowhere to issue a warning, primarily tasked with caring for him until he regains his adult form. Maintaining a delicate balance of distance, the butler watches over the growth of the 12 from afar.
