Mikey, Jeremy, Angie und Shoutmon sind zurück in Tokio. Sie versuchen, ihren Familien zu erklären, was sie in der Digi-Welt erlebt haben, doch diese können Shoutmon nicht sehen und verstehen nicht, wovon die Kinder sprechen. Kurze Zeit später erfährt Mikey von Omnimon, der ihm einst den Fusionslader gegeben hat, dass die Digi-Welt noch immer in Gefahr ist. Also entscheidet er sich, Angie und Jeremy zurückzulassen und in die Digi-Welt zurückzukehren.
Ending up back in their world, Taiki, Akari and Zenjirō learn that their time in the Digital World was about half a day in human world time and both of Taiki and Akari's family members have no faith on their words. Taiki later hears the voice who had granted him the Xros Loader, though is unable to find it. The next day, Taiki meet up with Akari and Zenjirō, telling them his intention to go back to the Digital World and save their friends over there. The voice eventually respond to his words leading them to it, revealed to be the DigiMemory of Omegamon. After fully materialising Shoutmon and explaining the origin of the DigiMemories, Omegamon reveals he has the power to return Taiki to the Digital World, but Akari and Zenjirō must stay behind. Just then, Tactimon, who was trapped in the real world and attacking the city, uses the electricity to give himself form and chase over Taiki. After Taiki fail to use his DigiMemory in the battle, Tactimon captures Akari and Zenjirō, demanding Taiki to hand over the Xros Loader. However, Akari and Zenjirō's passionate emotions give Taiki's Xros Loader a new power, allowing Shoutmon to digivolve into OmegaShoutmon who manages to destroy Tactimon. Taiki returns to the Digital World with Shoutmon, where his presence is noticed by Nene's brother, Yū, who is seen with DarkKnightmon and says that he wants to battle against Taiki.
