Our Last Crusade or the Rise of a New World anime
Astral mages control an Astral power, which is a force that permeates the entire world. The “Empire”, fearing its destructive power and persecution of those who demonstrate their talents, persecutes all who are able to. To escape their oppressors, the tormented mages founded the Nebulis Sovereignty. The war has raged for over a century, and the nations have been at bitter conflict ever since.
The great crime of releasing a witch imprisoned in prison is committed by the skilled knight Iska, who is sentenced to imprisonment. One year later, the Empire leadership decides to release him with the condition that Iska hunts down the “Ice Calamity witch”, a terrifying mage. Iska agrees to end the war in an attempt to bring it to an end. Coincidentally, Iska agrees to end the war.
Alice and Iska both long for a crusade to end suffering, woe and pain in the world. The strings of fate bind them together, creating a bond beyond coincidence.
