This page tells the story between Jessica Dixon and Sirena.
Jessica and Sirena (Serena/Blossom back then) knew each other before Jessica became Cure Lilac. However, Blossom was hypnotised by Queen Foxglove (her aunt) and her looks completely changed from colourful to dull. 2 days after the transformation was completed and Blossom, now known as Sirena, turned Jessica's family into Petaltrians. After several attempts to reason with Sirena, Jessica then decided to stand up for herself and a purple aura surrounded Jessica and, in the palace, one of the Flower Ribbons also had a purple aura around it and it shot out of the palace into Jessica's hands. She then transformed into Cure Lilac and purified her family.
