Beruka is a skilled assassin orphaned in the slums of Nohr at a young age. From the little memories she had of her parents, Beruka tells Odin in their supports that she received very little love from them and was thrown onto the streets, being forced to kill for survival before she reached the age of 10. In her support with Niles, Beruka states that her mother is deceased. She was adopted by a notable Nohrian assassin and was taught the art of assassination, though she reveals in her support with Oboro that she never received any love from him. Eventually, she became a notable assassin in her own right. One day, she was contracted to kill her adoptive father, a task she carried out with no remorse, stating that any personal feelings she may have can never make her falter in her mission.
