Our Last Crusade or the Rise of a New World Season Ⅱ

"The Empire": a mechanized utopia with highly developed science and technology.
"The Nebulis Sovereignty": a nation feared as the "Land of the Witches" whose people use paranormal power.
The two nations have been at war for a long time.

Iska, the strongest knight of the Empire, and Aliceliese Lou Nebulis IX, the princess of the Sovereignty who is also called Ice Calamity Witch, got to know each other through fierce battles, and they became worthy rivals who are drawn to each other for who they were and their ideals.

After destroying the ploys of the Empire and the Sovereignty at the independent nation of Alsamira, the two promised to see each other again and went their separate ways. But that promise came true rather unexpectedly.

Iska makes a deal with Sisbell, the little sister of Alice, and infiltrates the Sovereignty disguised as a guard. Alice visits the city of Riesbarten in the Sovereignty to search for Sisbell.

The chance reunion lights up the fire in their hearts once more. In the meantime, the spy from the Empire, "Purebred Subject E" is active behind the scenes in the Sovereignty, and the Empire’s secret mission, A Plot for the Queen's Assassination-Turned-Capture, is about to begin.

Whether they like it or not, fate is about to tear Iska and Alice apart. Will they resist fate, or...?
