Description
Prince Rūdo Bernstein IV, heir to Golt's throne, possesses a cold, calculating, manipulative, and devious personality that earns him deep resentment from his subjects. He exhibits a ruthless and violent disposition, known to threaten or kill purely out of annoyance.

In the primary timeline, Rūdo pursues domination over neighboring countries by exploiting Finis's song-based powers as a weapon of war. To secure control over her abilities, he traps Finis within the royal palace under the pretense of selecting her as his bride candidate. His strategic manipulation includes deceiving Finis into executing a disguised Henry, an act intended to eliminate opposition and consolidate his authority. This event directly triggers a catastrophic chain of events leading to widespread destruction.

An alternate timeline reveals variations: Rūdo has blonde hair instead of purple and refrains from initiating war against neighboring nations, instead adopting a stance of opposition. His father, the king, dies during Bazra's attack on the castle. Following this, Rūdo is present at Alea's crowning as queen, indicating a shift in his political status and influence.

Across both timelines, Rūdo remains a key figure in the kingdom's military and political conflicts, leveraging his royal position to advance his ambitions through coercion and violence. His actions consistently contribute to central conflicts involving the use of song-based powers for warfare and control.
