After performing a huge concert, Miku Izayoi invited Shido, Tohka and everyone for a day at a reserved indoor pool. Later at night, Shido keeps spotting a girl named Mayuri, who quickly disappeared after seeing her.
The next morning, Shido begins to see a huge mysterious sphere, which suddenly began to emit a mysterious spiritual wave to the Tengu City that should have regained its peace, but everyone else does not see it. Reine begins to suspect that the orb appearance is due to the emotions the 6 girls emits for their feelings to Shido. So she suggested that he should go on a date with each of the 6 girls in a randomly drawn order; 1st date is with Kaguya, 2nd is Miku, 3rd is Yoshino, 4th is Yuzuru, 5th is Kotori, with Tohka being the final one.
Through each date, Mayuri watches over Shido as he dated each of the six girls. Once he concluded each date, each of their energy from the orb will diminish, leading Kotori and the others to believe that the orb will disappear when all the dates are completed. On his final date with Tohka, Shido finally encountered Mayuri, who revealed to be born by the energy of the spirits and will disappear once her mission is completed.
Before Mayuri can take off after revealing her spirit to him, the orb that Mayuri named Caraveare suddenly turned even darker. It then grew a pair of wings and proceed to attack the city. It also kidnapped Mayuri before flying off. Tohka and the others start to battle against it while Shido and Kotori think of a plan to fight it. When Shido mention that he desires to save Mayuri, his words trigger the release of the sealed spirit powers of Tohka and the others, returning their power temporarily to them, allowing them to be even stronger in the fight against Caraveare.
After successfully rescuing Mayuri, Caraveare undergoes another transformation and attacks the group. Shido goes towards it to stop it, but it blasts Sandalphon away, and Shido almost falls with the creature preparing to release another blast until Tohka managed to somehow stop time and save him after receiving the other spirits' energy. She then destroys the creature for good before Mayuri shares her last kiss with Shido before disappearing, leaving behind a necklace similar to the one Shido bought for Yuzuru and the lollipop he bought for Kotori, before saying to him that she was not born to disappear, but to love him, like the others. Everyone, including Shido, mourn Mayuri as she vanishes. It is then revealed that Kurumi was the one who had stopped time with Zafkiel to ensure Shido's survival. She then disappears into the shadows, saying that Shido owes her yet another favor.
A few days later, Shido and Tohka watch as the damage from the incident is repaired. The film concludes with Tohka and the rest requesting more dates with Shido, but he leaves as the girls chase him.
