The King of Silverland and father of Sapphire publicly declares his newborn child male to secure the royal succession, preventing the antagonistic Duke Duralumin from claiming the throne. This deception is a political necessity due to Silverland's laws prohibiting female heirs from inheriting the crown.

Duke Duralumin, backed by the external aggressor Mr. X and the X-Union, orchestrates a coup, capturing the King and the Queen. The King is executed by being dropped into the sea. Following the kingdom's liberation from Mr. X's forces, divine intervention reverses his death; the angel Tink sacrifices his life to appeal to God, resurrecting the King.

Throughout, the King demonstrates a protective commitment to his family and Silverland's stability. His actions in maintaining Sapphire's secret and resisting Duralumin's schemes are driven by a desire to uphold justice in the kingdom. His relationship with Sapphire and the Queen is central to the theme of familial bonds amid political turmoil.
