Now Revealed! The Secret of the Digimon Hunt!

Synopsis
One morning Tagiru arrives at school only to find it transformed to DigiQuartz. He believes this to be the work of a Tsumemon he sees on the scene, but when he tries to catch it, it Digivolves to Keramon before his eyes. Ryouma appears and saves Tagiru, but Keramon escapes, transforming the town to DigiQuartz as it flees. Soon the whole town is transformed and its human residents gone. Finally Mikey calls Tagiru and Ryouma to a strategy meeting, where they puzzle over how a Digimon can Digivolve without a human partner, and how to save the humans who have been erased from the town.
