After the defeat of Myotismon, things begin to return to normal, everyone's relieved, until one day something even stranger in the sky. It's an upsidedown image of the Digital World, showing that while the DigiDestined have been fighting Myotismon for only a few days, centuries have passed in the Digital World revealing that something is terribly wrong. The DigiDestined decide to head back to the Digital World right away to investigate and sort the problem out. Now they must face an evil that can bring forth more destruction and darkness than even Myotismon.
