This is the final battlefield between you and me, or the second season of the holy war to create the world.

A technologically advanced, mechanized ideal kingdom, the Empire. Driven by supernatural powers and the Stargazing Art, the Nebilis Imperial Court, known as the 'Witch's Country,' is feared by many. The long war between the two nations is still ongoing. The Empire's strongest warrior, Iska, and the Imperial Court princess, Alice Riche, also known as the 'Ice Calamity Witch,' gradually come to understand each other's true feelings through fierce battles, drawn to each other's life philosophies and ideals, becoming formidable rivals. The two crush the Empire and the Imperial Court's conspiracy in the independent nation of Arsamira. After promising to meet again someday, they each walk their own paths, yet fulfill their promise in an unexpected way. Iska strikes a deal with Alice's sister, Sisbell, infiltrating the Imperial Court as her bodyguard. Alice, in search of Sisbell, arrives in the Imperial Court's city of Risburton. Their chance reunion ignites their hearts even more fiercely; however, at the same time, a spy from the Empire, 'Pureblood Subject E,' secretly operates within the Imperial Court, and the Empire's 'Special Mission: Queen Capture Plan' is about to be launched. Iska and Alice's relationship is on the brink of being torn apart. Can they ultimately resist this fate?
