Everyone in the world uses smartphone apps. But inside them lurks unknown creatures called Appli Monsters, or Appmon. The Appmon are AI lifeforms with the ability to think and act, and exist in the boundary between the human world and digital space. In the vast sea of the internet, the last boss AI Leviathan takes control of the Appmon with a virus and begins hacking every system, thus starting to control the human world from the world of the net. Haru Shinkai is led to acquire the Appli Drive, and uses it to materialize Gatchmon, a search app monster. (Source: ANN)

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.
