A brave samurai woman, a one-armed Empress, and a dying clan searching for a breakthrough...

War is near, and empress Megumi and samurai Akari cannot trust anyone else to save their clan. While out on a mission, Akari is shocked to discover technology she's never seen before in the hands of their enemies. How can they fight against guns and cannons with only swords?

Noble-born Megumi is forced into a position she never wanted, and her disloyal court is searching tirelessly for any reason to have her dethroned and killed. How can she lead her people to safety if they won't accept her?

To defeat the evil forces conspiring against them, Akari and Megumi may have to give up everything. Is their loyalty and bravery enough to defeat a darkness more powerful than anything they've ever seen? Or will they sacrifice everything in vain?
