A childhood friend of Germán Luís and Bernardo Dión, Anna was the oldest daughter of the previous owner of the Garo title. Sometime after her father's death, Anna remained in the Makai Order so she can pass her father's title to the first male child she gives birth to while her younger sister Esmeralda was adopted into a noble family. Eventually, after Anna marries Germán and bears his son, she is framed by Mendoza for causing the illness afflicting King Fernando.
Placing the life of her son before her own as he is birthed at time, Anna uses her magic to create the burn-like seal markings that protect the newborn León from the flames. Though Anna died in the flames as Germán saves their child, her magic continues to protect León from any form of danger after her death. Her Anna protects León one final time during his final battle with Mendoza, engulfing the fallen Makai Priest in her seal's flames for eternity while guiding her son back to the human world.
