"Aurelia, the lucky-star baby of the Sterling family, is swapped and abandoned by maid Jocasta, then raised by commoner Martha. Endowed with powerful S-rank dragon magic, she is constantly bullied by fake heiress Cordelia at the noble kindergarten. At Cordelia’s birthday banquet, a blood-line scroll reveals Aurelia’s true identity. Consumed by hatred, Jocasta gets possessed by a dark soul trying to seize Aurelia’s primordial black-dragon blood. Helped by her guardian little black dragon, Aurelia defeats the evil force. She reunites with Martha and her birth parents, while the culprits are exiled."
