Aozora Kaede is on the run. Forced to flee from home after a violent disagreement with her aunt and cousin, she is a wanderer with a spirit wolf as her only companion. Homura Imari lives in the lap of luxury. As the daughter of a daimyo, her duties are clear: stay home and learn how to rule the province she will inherit. But when fate brings the two of them together, Imari notices Kaede’s connection to the spirits and decides to ask for a favor. She needs someone to guide her to Hongshan, a faraway mountain where a magical blacksmith is rumored to live—a blacksmith who can hopefully replace her missing left hand. Together, they must travel across the treacherous Jade Sea, protect themselves from Kaede’s vengeful family, and perhaps even save the Empire from destruction.
