Following the defeat of Bagramon, a year passes before Taiki Kudou and Yuu Amano unite with Tagiru Akashi to form a basketball team. Tagiru stumbles upon the enigmatic DigiQuartz, a realm bridging the human and digital worlds. Across the globe, children acquire Xros Loaders and Digimon partners for the 'Digimon Hunt' competition. As Digimon stray into the DigiQuartz, they thrive on human negativity, growing formidable but dangerously aggressive. Tasked with thwarting these threats, the Digimon Hunters, including the mischievous Gumdramon, strive to maintain peace. Unbeknownst to Tagiru, Taiki and Yuu harbor past ties to Digimon. Amidst their pursuits to dominate the Digimon Hunt, a dark presence emerges from the DigiQuartz, revealing a game with stakes far beyond mere amusement.
