Cecily's a blushing knight in shining armor. Unfortunately, it seems most battles end with her as the damsel in distress. Her lack of skill and distaste for violence make her an unlikely heroine - until the brooding blacksmith Luke comes to her aid, using his powerful magic to forge blades of supernatural strength. Cecily wields this sacred steel and charges forth to face a dangerous new threat. A cloaked fiend is unleashing demons upon the land, and though he lurks in shadows, the villain is much closer than Cecily can imagine.
In an era where aliens have invaded and taken over feudal Tokyo, an unemployed samurai finds work however he can.
