A former Nohrian assassin trained from childhood to kill without hesitation, Beruka lives a life shaped by shadows and discipline. Taken in by the criminal underworld after losing her parents, she honed her skills as a contract killer, her emotions dulled and her trust scarce.

Her path changed upon meeting Princess Camilla, who offered her loyalty and purpose beyond mere survival.

Though her demeanor is cold and expressionless, she feels deeply yet struggles to express it, often showing care through silent protection rather than words.

A master of aerial combat on her wyvern, she is silent, deadly, and unshakably loyal, standing as a living weapon who nonetheless searches quietly for purpose beyond killing.
