Our Last Crusade or the Rise of a New World

The Empire benefits from vast knowledge, while Nebulis is feared as the "Witches' Territory". On the battlefield between these two nations, a young man and a young woman have crossed paths: Iska, the youngest swordsman ever recorded in the history of the Empire, and Aliceliese Lou Nebulis IX, the princess of the Imperial dynasty, known as the "Ice Witch".

As both are avowed adversaries, they are supposed to fight to the death. Nevertheless, Iska has fallen in love with Aliceliese's beauty and dignity. For her part, she is fascinated by his power and way of life.

Together, they will strive to establish peace between their two kingdoms.
