The Chosen Children meet the ruler of File Island, Devimon, the controller of the Black Gears. He, along with Ogremon and a possessed Leomon, attacks the children, who manage to escape. They end up in a mysterious mansion which turns out to be an illusion created by Devimon. Devimon breaks File Island into multiple smaller islands and separates the kids on different islands. Devimon nearly gets Taichi, but the light emitted from Taichi's Digivice frees Leomon, who holds off Devimon to give Tai time to get away at the cost of being recaptured.
