Repentant for abandoning her infant son, Diego Brando, she dives into a flooding river to save him. Until her death, she taught Diego pride and nobility.

Diego's mother is a young woman who has long dark hair, except for two locks of light hair at the front. She wears a dress and boots. Although she buried her infant son alive, Diego's mother quickly changes her mind and dedicates herself entirely to his well-being afterward. Despite living in poverty, she makes it a point to teach her son pride and seeks to keep her dignity. She makes any sacrifices to raise Diego, going as far as burning her own hands with hot soup on a daily basis for a month when they didn't have cups.

Diego's mother lived in an impoverished region on the island of Britain with her husband, Dario. At some point in time, they had Diego, but felt forced to dispose of him due to their poverty-stricken lives. In the cover of night, the two went up into the mountains and dug a hole with the intent of burying the child. After wrapping the infant Diego in a white cloth, they placed him in the hole and left, having buried him alive. Soon after, a storm occurred and the water in the river increased and started to flood. The flood caused some type of erosion, and the baby was submerged from the ground and forced downstream. Diego's mother had a change of heart and bravely dove into the river after her baby, even after Dario hit her for "scorning her husband".
