One day, a Digimon Xros Loader appears before Taiki, an exceptionally warmhearted seventh grader, along with Shoutmon's voice, asking for his help. The D Xros Loader is an essential item that is capable of transferring power to Digimon by means of 'DigiXros'. He was chosen as a 'General' to control it. Taiki and his friends are thrown into a parallel universe, the Digital World. Due to the appearance of rival and enemy Digimon, the Digital World has been driven into a state of 'Xros Wars', a large-scale war with battles like those of the Sengoku period. Taiki and Shoutmon form a Digimon Army using the D Xros Loader and battle against formidable opponents with 'DigiXros'.
