Netto and his personal Net Navi called Rockman are called into duty once more to save their world from an evil organization called Nebula. These mysterious "Dark Loids" are out to destroy all humans, by creating Dimensional Areas and attacking the real world! Using a Synchro Chip, Netto is able to perform a new special ability called "Cross Fusion", which enables him to merge with Rockman. It's up to Netto and Rockman, along with long-time rivals Enzan and Blues, to thwart all evil, and save their world once again!
All Takato ever wanted was his very own Digimon; all Ruki ever wanted was a strong Digimon; and all Jen ever wanted was a partner Digimon. Their wish came true, but along with it a string of Digimon came to destroy the world and conquer it. This unlikely trio must now fight with their partner Digimon created from the mysterious blue card and stop the impending doom that is coming their way. Together with some other friends they explore the Digital Zone to find out what is happening, and to discover the mystery behind the D-Reaper. This is not just a regular digital monsters card game, because this time, the Digimon are real!
For the first time in both of these series, the digital enemies (viruses and evil digimon) invade the real world and threaten the safety of everyone there. In response, the digi-destined and net battlers also find a way to bring their digital friends into the real world, and the battles begin. Both groups have to deal with the safety of people around them, threats that pop up without warning, and the secrecy needed to protect those they care about.
