Our Last Crusade or the Rise of a New World

After their brief but fateful encounter, Iska and Alice made an impression on each other, resulting in some sleepless nights. Despite being on the opposing sides of the war, they soon learn that 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. When Iska and Alice meet again, they aren't prepared for what's coming for them.

The members of Unit N07 successfully locate the vortex, but the Sovereignty had 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. They are reunited by fate, but everything is jeopardized when Rin makes a big miscalculation.
