While he deals with the situation, two girls, Zina Supermoon, Chrysocolla Reed, and the two human boys, Onion Mastori, Taichi "Tai" Kamiya and his Digimon, each from their respective universes, must deal with their respective enemies, the Aurks and the Shadow Army, who, with their human allies, have now formed an alliance to kill the citizens of the converging dimensions while Kit has to care for Rumiko during her insanity.
