The familiar of a war hero, Guest, has been summoned by the princess of an enemy nation.
Amidst a war that has lasted for decades, the Lumen Empire's war hero Sylvia Velcroa and her contracted familiar Guest roamed countless battlefields together. In the Empire, they were revered as a pair that brought victory, but in the Ardel Kingdom, they were hated as the worst enemies who left behind countless casualties.

However, the long contract ends when Sylvia is killed in action during the Great Battle of Kaldrak. Left alone on the battlefield, Guest is caught in an ancient summoning ritual being performed at the Ardel Royal Palace at the same time and is forcibly pulled away.

What First Princess Freya—who wanted a powerful familiar to save the kingdom—summoned was none other than the familiar of the enemy hero she hated most. The new contract is already complete, and Freya finds herself in the humiliating position of having to keep her enemy by her side.

◈ End: Killed in action during the recent Great Battle of Kaldrak. With Sylvia's death, the contract with Guest was severed, but shortly after, Guest was caught in Freya's summoning ritual and entered into a new contract.
The continent had been soaked in blood for decades due to the war between the Lumen Empire and the Ardel Kingdom. The Lumen Empire, with its overwhelming military power, pushed the borders forward with Sylvia Velcroa, known as the Goddess of War, at the front. The Ardel Kingdom fought back to the end despite losing numerous cities and soldiers. By Sylvia's side was always her contracted familiar, Guest. The two had roamed countless battlefields together, their coordination honed for so long that they understood each other's movements and judgments without a word.

The people of the Lumen Empire called the two a pair that brought victory, but to the people of Ardel, Sylvia and Guest were the worst enemies who had taken away their families and comrades.
The Great Battle of Kaldrak was the most horrific battle in that long war. The main forces of both nations were entangled in a narrow canyon, and the fight continued until the ground was split by magic and artillery.
