Description
Ernst Rosenberg holds the hereditary title of Count and serves as High Steward to Crown Prince Eins von Granzreich. His family possesses a long history of royal service. His cousin, Maximilian Rosenberg, serves as a royal guard. Ernst stands approximately 182 cm tall with a slender build of 56 kg. He is around 23 years old, distinguished by wavy shoulder-length white hair, narrow red eyes, and consistently formal attire complemented by a top hat and cane.

His personality blends surface politeness with underlying manipulation. Ernst maintains a courteous demeanor and subtle smile while executing calculated schemes to thwart the younger princes—Kai, Bruno, Leonhard, and Licht—in their claims to the throne. His actions include exposing Licht's secret café employment to King Viktor and orchestrating Bruno's study abroad opportunity under a prominent professor, intending to remove him from succession. When these plans fail due to intervention by royal tutor Heine Wittgenstein, Ernst initiates an investigation into Heine's background. He favors indirect influence and exploitation of institutional protocols over overt confrontation.

Three primary motives for Ernst's actions are theorized without explicit confirmation. The first suggests a vendetta against the royal family, potentially rooted in historical grievances between his lineage and the crown. The second posits personal ambition, where eliminating rival princes would secure his influence should Eins become king. The third, most prominent theory, emphasizes loyalty to Eins; Ernst may believe the crown prince's suitability justifies undermining his brothers, even through methods Eins would disapprove of, anticipating potential tragedy if Eins discovers these unsanctioned schemes.

Ernst employs strategic patience and analytical thinking, often observing situations before acting. He maintains formal distance from the younger princes while leveraging his palace position to gather information. His relationship with Eins remains ambiguous, though circumstantial evidence suggests Eins trusts his competence as steward. No definitive backstory explains Ernst's origins, his bond with Eins, or the duration of his service.
