Our Last Crusade or the Rise of a New World

Two nations, the Empire and the Nebulis Sovereignty, have been at war for 100 years; imprisoned for freeing a witch, Iska is given a chance at freedom; in exchange, he must take down a powerful astral mage known as the Ice Calamity Witch.

After their brief but fateful encounter, Iska and Alice made an impression on each other, resulting in some sleepless nights; they soon realize they have much more in common than they thought.

Iska is given a new mission to apprehend the Ice Calamity Witch; by accomplishing the mission, Iska will be a step closer to realizing his dream of a peace treaty.

The members of Unit N07 successfully locate the vortex, but the Sovereignty has already found it; after Mismis is captured, Iska must fight against Kissing, a purebred, to get her back before the Empire attacks the Sovereignty base.

Iska and Mismis survive the eruption of the vortex, but the team doesn't escape unscathed; meanwhile, Alice decides to go search for Iska in Ein again.
