One day at the beginning of a new semester, Purple loses her magic wand and her only princess dictionary while trying to protect her friend Leo from the villainous Blobs, Black Diamond's subordinates. Then, White Gold, the guardian of the sea, senses the dark energy and gives her a new catcher and princess dictionary as gifts. With this, Purple creates new bubble gems for the other princesses and upgrades their magic, but she is unable to create a bubble gem with her own color.
The seven mermaid princesses, along with their new human friends including Leo's senior student Gray, the seven mermaids battle the returning and more powerful Black Dia. Without her own bubble gem, can Purple protect the sea world, the humans, and the land world?
