History
Bianca and her identical twin sister, Ciara were the biological daughters of an witch practitioner named Clara.

In 2000, Clara's close friend, Erica Miller, an Serena Witch, faced the Darklighter Krola and a Horned Demon in an alley in L.A. While Erica's sisters fought the evil pair, Erica found out that Clara was injured and tended to her that had been shot by a stray Darklighter arrow. However, Erica quickly realized it was too late to save her. In her last words, Clara asked Erica to look after the twins. Erica agreed to look after them and Clara dies. Months later, Bianca and Ciara were officially Erica and Todd's daughters.

Twin Witches
Years later, now young women, Bianca and Ciara moved to to Los Angeles and in the Serena House with their grandmother, Agatha
