44 years ago, a great war known as the Valbanill War raged the land. One of the war’s most dangerous weapons was the Demon Contract, where humans sacrifice their bodies to become powerful demons. Realizing the damages the contracts have caused the land, the surviving nations made peace and banned the use of the Demon contracts.
Cecily Cambell is a 3rd generation Knight from Housman, one of the cities of the Independent Trade Cities, a democratic federation of cities. As her grandfather was one of the founders of the Independent Trade Cities, she is proud of her heritage and wishes to protect her city as a knight, like her father and grandfather before her. One day, she fights a mad veteran of the war causing trouble in the market, and, inexperienced and overmatched, faces defeat. But she is saved by a mysterious blacksmith named Luke Ainsworth. Cecily is impressed by Luke’s katana, a weapon she has never seen before, and asks him to make one for her. Her involvement with Luke will bring her to an adventure she never expected.
When Cecily sees his katana cut a sword in two (as per typical of the supposed magical qualities katana have over broadswords), the same sword that shattered her own, she desires one of her own and persistently asks him to forge one for her. While he often comments on her pride and hotheaded personality and her large breasts, he comes to like and admire Cecily. Her will to protect the city and everyone within it reminds him of Lisa Oakwood, the love of his youth who was slain before his eyes by Valbanill.
