Digimon Adventure tri. 4: Soushitsu

The DigiDestined return to the Digital World after the Reboot, relieved to reunite with their Digimon partners but devastated to discover that the Digimon no longer remember the bonds they once shared. Most begin rebuilding those relationships from the beginning, while Sora struggles when Biyomon refuses to accept her closeness.

An attack scatters the group across the altered Digital World, and Meicoomon's ability to retain her memories becomes increasingly important. In the human world, Daigo Nishijima learns that an unknown force is pursuing 'Libra,' believed to refer to Meicoomon. As old truths surface and the reunited partners are tested again, the children begin to see that the Reboot solved far less than they hoped.
