Some months after the Minor League came to an end and the Near-Darkest Day was prevented, the Galar Angels are more than happy to enjoy the newfound peace in their lives. In fact, Amane's taking that time to go on vacation to the Johto region with her family! After hearing the legend of Celebi from her grandparents, Amane decides to pay its residence in Ilex Forest a visit, but when she visits its shrine, she finds not only Celebi, but a strange girl who bears a strong resemblance to her and Kamala, and strange monsters who want her dead! A hectic battle reveals that this girl is her and Kamala's future daughter and the leader of a group of Angels from the future, who are stuck in a fight against a tyrannical and powerful dictator named Thismia with the ability to control time! Celebi's attempt to save Amane and Gautami from Thismia sends them 150 years into the Johto region's past, where they must seek out the legendary Ho-Oh to restore Celebi's power. Meanwhile, the other Angels are ambushed by Thismia's forces, but manage to flee through the very same portals they took and arrive in the distant future, where they team up with the other future Angels to find a way back to their time and also foil Thismia's plans to capture the Legendary Pokemon Lugia. Together, the Angels of both the present and future will fight to save the world from Thismia's tyranny all across time! ║ Fancast for a hypothetical Pokemon magical girl anime movie.
