Sekt Rondahl Karlon Rhoden Sahdiay

Sekt Rondahl Karlon Rhoden Sahdiay is the First Prince of the Rhoden Kingdom in Skeleton Knight in Another World.

He is the eldest son of King Karlon Delfriet Rhoden Olav and his second wife, Lefitia Rhoden Sahdiay. Sekt presents a polished, gentle, and charming exterior with a handsome appearance (often described with light brown or blonde hair and blue eyes), but he hides a cunning, ruthless, and calculating personality.

He engages in a fierce power struggle for the throne against his half-siblings, including Prince Dakares and Princess Yuriarna, showing willingness to use extreme measures like assassination and framing others to eliminate rivals—all while justifying his actions as being for the kingdom's greater good (a well-intentioned extremist mindset). He leads his own political faction, is secretly supported by the Great West Revlon Empire, and demonstrates shrewd political maneuvering.

In the story, his facade fools many, but some characters sense something off or "fake" about him. He is voiced by Kengo Kawanishi in Japanese (and Grant Paulsen in English).
