Bronya was the heir to the current Supreme Guardian of Belobog, Cocolia and commander to the Silvermane Guards. After Cocolia's death, Bronya took over her role. Bronya possesses pride befitting of a princess, but also the determination and integrity of a soldier. Despite being the heir, she is not blood-related to Cocolia but an adopted daughter. She maintains her serious and deadpan attitude most of the time. However, on rare occasions, it does crack to reveal a warmer side to her.
