Fate intervened on the perpetual battlefield of two rival empires - the 'Country of Witches' and the 'Intelligence Empire' - with a chance encounter between a boy and a girl. The encounter brought together Aliceliese, the most powerful ice witch at the Imperial Household Agency, and Iska, the youngest and most formidable swordsman in the empire's history.
Aliceliese challenged Iska to capture her and fulfill his deepest desires, while Iska challenged Aliceliese to defeat him, hoping it would lead to the unification of their divided world. Though they initially intended to eliminate each other, Iska was taken by the girl's elegance and nobility, while the girl was captivated by the boy's unwavering courage and way of life. But their situations prohibited them from joining forces, leaving them with only one option - to triumph over the other.
