The Sacred Blacksmith (聖剣の刀鍛冶（ブラックスミス）)

Storyline

The knight Cecily wants to defend the weak, but her lack of skill makes her an unlikely heroine - until the blacksmith Luke comes to her aid, using magic to forge blades of supernatural strength. Cecily wields this sacred steel and charges forth to face a new threat; a cloaked fiend is unleashing demons upon the land, and though he lurks in shadows, the villain is closer than Cecily knows.
