Rosa was a highly skilled and powerful Umbra Witch as well as Bayonetta's beloved mother. 500 years before the events of the first game, Rosa fell in love with a Lumen Sage, Balder. The two of them conceived a child, breaking the law between the two clans that stated the intersection of light and dark would bring destruction to the world. When Cereza was eventually born, Rosa and Balder were punished greatly by their respective clans. She was imprisoned for the rest of her life and Balder was exiled by his clan whilst Cereza was raised amongst the Witches as a black sheep. Rosa was eventually killed during the Witch Hunts during the attacks on Vigrid and the Crescent Valley.
