Taiki Kudo is an upbeat boy with a desire to help those in need, although tends to overexert himself. One day, when digital devices start going beserk, he hears the voice of a Digimon named Shoutmon who is on the verge of death. Wanting to help him, Taiki is given a Digivice known as a Xros Loader, and he and his friends Akari Hinomoto and Zenjirou Tsurugi are warped to the Digital World where they meet Shoutmon's allies, Ballistamon, Starmon #2, and the Pickmons. By using the power of the Xros Loader, Taiki can perform a Digi Xros which can fuse his allies together into powerful forms. Taiki and his friends use this ability to fight the forces of the Bagura Empire.
