The Second Empress hires a spear-wielding woman to save her son from the Mikado (emperor) who believes the young prince is possessed by a water demon foretold to bring a terrible drought upon the land should he live.
Balsa the spearwoman is a wandering warrior, who takes on the task of saving lives, in atonement for a past sin. On her journey, she happens to save a prince, and is tasked with becoming his bodyguard. And he is going to need one, for his own father, the emperor, wants him dead.—Anonymous
