In the near future, rampant genetic disorders have wreaked havoc on the human population. Society has reverted to a medieval state, in which teenagers await the horrific mutations that come with adulthood.
In this desperate wasteland, a new class of ''guard maids'' arises - young woman trained in the arts of servitude and combat. Sarai knows that her hours are precious, and enjoys her work, but she brings more to it than loyalty - she also applies her own bleak sense of justice.
