In a fantasy world where many races - elves, beastmen, dragons, fairies, and humans - coexist under fragile peace, the balance is shattered with the Great War. Every 40,000 to 80,000 years, a Demon King is born, plunging the world into chaos. An ancient alliance of kingdoms forms the Grand Church of Light, uniting their strongest warriors and high priests to lead the charge.
Among them stand two of the most gifted - Polaris, the ethereal Elf High Priest, calm, breathtaking, and one of the most powerful, and Kanna, the fierce and determined of Beastman clan, heir to their throne, a warrior priestess known for her unmatched and fiery spirit. Bound by years of friendship and trust, they now march under the cause - each leading their people into a war that may decide the fate of their world.
But as blades clash and the end draws near, the bond between them begins to blur the lines between duty and desire.
When the heart wages its own silent battle, what will win - devotion to the alliance, or the emotions they both try to hide?
And when the final war begins, will friendship be their greatest strength... or their deepest tragedy?
