The story begins when the protagonist Hikaru meets aliens Lala, Prunce, and Fuwa while watching the night sky. She learns of the Star Palace, where the 12 Star Princesses of the constellations kept the balance of the universe until they were attacked. Lala is searching for the legendary Precure warriors to help find the 12 scattered Princess Star Color Pens and revive the princesses. When Fuwa is captured by an enemy, Hikaru wishes to save Fuwa, and a Star Color Pendent and a Star Color Pen appear to allow her to transform into Cure Star. From then on she works to collect the pens and raise Fuwa, who is the key to reviving the princesses.

A seed of hope descends from the sky, landing atop Flappy's head and sprouting between his ears. Goyaan is sent after the seed of hope and uses a seed of despair to transform an Uzaina, causing big trouble for the Precure!

Aira Harune, a clumsy yet happy-go-lucky girl, is suddenly dragged into the popular world of Prism Shows—an idol show based on figure skating, where performers called Prism Stars wear outfits encased in Prism Stones and perform stylistic Prism Jumps. Captivated by the dazzling fashion and gorgeous Prism Jumps, Aira decides to become a Prism Star herself. She soon encounters the hot-headed Rizumu Rhythm Amamiya, who desires to perform the legendary Prism Jump “Aurora Rising”; as well as the prideful Mion Takamine, who dreams of becoming the brightest Prism Star above the rest. The journey of these girls is marked by friendship, growth, and unexpected encounters. Can they perform Prism Jumps high enough to reach their dreams and become the next Prism Queens?
