A generation ago, an abominable war foisted a "devil's contract" upon the soldiers of countries warring on a single continent. In the middle of the legacies of that war, Cecily Campbell, a daughter of a noble house with diminished power, joined the knighthood of the free city she lives in.

One day Cecily encounters a man who dispatches some hoodlums with one sweep of a mysterious sword. The man possesses the power on the same level of the "devil's contract" that has become taboo, now that peace has been restored. Cecily has been searching for a blacksmith who can repair an old sword she inherited from her father, and that mysterious young man happens to be a grumpy blacksmith named Luke. This encounter launches their adventures together.
