However, his firstborn son, Prince Bojji, is born deaf, diminutive, and seemingly powerless. Despite his kind heart and sharp intellect, Bojji is mocked by his kingdom as a fool unfit to rule. The tragedy deepens when Bosse mysteriously passes away, and Bojji’s cunning stepmother, Hilling, manipulates the succession to favor her biological son, the arrogant Prince Daida.Amidst this isolation, Bojji befriends Kage, the sole surviving member of the Shadow Clan, a race of assassins wiped out for their dark deeds.

Kage vows to become Bojji’s loyal protector.
