Wanting to find out the full story behind the Digimon Hunt, Xros Heart finds a lead in a mythical Digimon named MetallifeKuwagamon. Tagiru’s insect-collecting classmate Kaneda enters DigiQuartz with Tagiru and Hideaki. Later on, to Kaneda’s dismay, the bug he caught is actually MetallifeKuwagamon who later on takes the boy as a hostage to cover his escape. Eventually, Tagiru and the others find MetallifeKuwagamon with Arresterdramon defeating him while Tagiru saves Kaneda. However, Tagiru realizes MetallifeKuwagamon cannot be captured as the Digimon reveals that his data belongs to an evil Digimon Hunter. Suddenly, before he can reveals his master’s identity, an evil being with red eyes and mouth deletes MetallifeKuwagamon before attempting to suck the Digimon Hunters into it. But at the very last minute, Taichi Yagami (who arrives with WarGreymon) and Masaru Daimon (who arrives with ShineGreymon) arrive to the Hunters’ aid.
