For centuries the Rōjū council silenced all who opposed them, spreading lies and killing innocents in order to maintain the status quo and ensure that female Kisōshi were little more than a long-forgotten myth. Now that Mishi and Taka have helped to depose the corrupt council, the land of Gensokai is reeling as it takes its first steps towards recovery. As the New Council attempts to corral the renegade allies of the defunct regime, Taka is asked to take charge of a frontline infirmary, putting her in the heart of the battle. To survive, she will have to rely on a person she cannot possibly trust.

Meanwhile, Mishi is asked to lure a vicious band of mountain raiders into the open--a mission that has proven fatal to all who have attempted it so far. Making matters worse, Mishi's mind keeps betraying her and she fears that her kisō and katana will betray her next. As the two friends fight to re-establish the peace in their homeland, the only question is where the next betrayal will come from, and if Mishi and Taka will have the strength to survive it.
