After Meicoomon's rampage and the Reboot, Taichi and the others leave behind a distressed Meiko and head to the Digital World. They reunited to their partner Digimon, but they have memories of the time with the Chosen Children. They once again try to forge new connections, but only Biyomon is wary, telling Sora that she doesn't know anything about the past. While Sora normally thinks of others even before herself, she now has distrust in her heart. As Sora stands heartbroken, Taichi and Yamato cannot find the words to help her.
A tearful Meicoomon appears and disappears again. For some reason, she retained her past memories, and is searching for Meiko. Upon seeing Meicoomon, the kids resolve to journey through the Digital World to save her, but a man with the Dark Masters at his command stands in their way.
Back in the real world, Nishijima receives a notice that Himekawa has disappeared. When he investigates, he learns that she has had a hidden goal behind all her actions thus far.
