Summoned from a diverse range of worlds and time periods to save a mysterious land at the brink of destruction, the champions of Warriors All-Stars find themselves in the middle of a clash for control. When a magical power source dries up after the king’s passing, princess Tamaki performs a ritual to summon saviors in times of dire need, but her power spirals out of control and scatters them across the domain. As the legend foretells that the land’s liberator will be crowned its new ruler, Tamaki sets out at once to seek the new arrivals and restore peace to the kingdom. However, so do her rivals Setsuna and Shiki – descendants of the royal family who also vie for the throne. Uncertain of their fate, the champions are split into three separate groups with no choice but to duke it out for dominance.
