Sixth and final Digimon Adventure tri film.

Fifth Digimon Adventure tri film.

The Chosen Children have been reunited with their Digimon partners, who no longer remember them due to the effects of a digital reset. While everyone tries to reconnect with their digital monsters, Sora Takenouchi encounters resistance from Piyomon, who stubbornly refuses to speak to her. Suddenly, an attack by a hostile Digimon separates the group, scattering them and their Digimon across the Digital World. Back in the human world, Daigo Nishijima of the Incorporated Administrative Agency receives a warning that a new entity is in pursuit of "Libra," which he believes to be an alias for Meicoomon. For some reason, Meicoomon retains all of her memories and therefore still recalls her partner Meiko Mochizuki, who has come alone to the Digital World to find her. If they hope to identify what other forces have been driving the incidents thus far, the Chosen Children must survive the obstacles of the recreated Digital World and make their way back home.

The Chosen Children are in shock after the betrayal of Meicoomon, the digital monster who had recently joined their group alongside her human partner, Meiko Mochizuki. Koushirou Izumi is determined to diagnose the infection that took control of Meicoomon. Meanwhile, Takeru Takaishi realizes that his own partner, Patamon, is starting to exhibit alarming symptoms similar to that of other infected Digimon, like Meicoomon. Just then, the Chosen Children receive a message from the mysterious entity Homeostasis, who informs them that their world is in danger of total destruction—and the Digital World, the home of the Digimon, is too. Homeostasis plans to enact a "Reboot," which will reset all the data that makes up the Digital World and eradicate the infection. However, the Reboot will also erase the memories of all Digimon, including the Childrens' partners. Can the Chosen Children stop Meicoomon before the Reboot becomes necessary, or is this the end of their time together with their Digimon? [Written by MAL Rewrite]
