In the realm of idol princesses known as AiPri, Himari Aozora has always dreamed of this magical world. When she was young, she made a promise with her best friend, Mitsuki Hoshikawa, that they would both debut as AiPris. But Himari's shyness has almost caused her to give up on that cherished goal.
As freshmen at Paradise Private Academy, Himari and Mitsuki start their school life together. On the first day, Himari gets lost trying to find her way back to the dormitory and stumbles upon a room glowing with a soft pink light. Stepping inside, she is surrounded by the glow and transported to the AiPriVerse—the enchanted stage where AiPris perform—with a new bracelet appearing on her wrist.
Without planning it, Himari ends up taking part in the newcomer auditions in the AiPriVerse, and her performance catches the attention of the Paradise Academy Student Council. They offer to become her producers, but only if she keeps her AiPri activities a secret. At the same time, Mitsuki is also secretly an AiPri, hiding that fact from Himari. As the two work toward their childhood dream of performing together, the academy’s principal threatens to ban all AiPri activities, making their mission even harder.
