Takuya, Tommy and J.P. are rescued by the Human Digimon Village that is leaded by Darkmon, suddenly, three Beast Digimon begin to attack the village, only to be killed by the Human Digimon Army. Zoe and Koji are at the Beast Digimon Village that is leaded by HippoGryphmon, where some Human Digimon attack becuase of the previous attack, but are also killed soon after they arrive.

The two digimon and some baby digimon take the Legendary Warriors to a secret ruin, where there's a legend, soon after, some Human Digimon and Beast Digimon find them and begin to fight eachother. Takuya turns into Agunimon and Koji into KendoGarurumon to stop them, the digimon go to their respective villages. The Human and Beast Digimon begin to fight, Takuya and Koji agree to help the Humand and Beast army respectably so that the baby digimon, Bearmon and Kotomon can escape to the ruins and fix the wall so they can read the legend. During the fight, Takuya turns into BurningGreymon and Koji into Lobomon to stop them. J.P. and Zoe discover and tell everyone that Darkmon and HippoGryphomon are actually Murmuxmon, a digimon that can change form, but it is too late, as Murmuxmon revives the evil digimon, Ornithmon. Ornithmon kills Kotomon, but his death allows AncientGreymon and AncientGarurumon to appear and kill Ornithmon and Murmuxmon.
