Simoun

The sacred aircraft of Simulacrum were meant for prayer, but war has turned their priestess-pilots into the nation's defenders. Only girls who have not undergone the ceremony that determines their adult sex can fly these machines, making military duty inseparable from a deeply personal choice.

Aer joins the battered Chor Tempest squadron eager to take to the sky. Her chosen partner, Neviril, is still mourning the loss of her previous companion. As neighboring powers seek the secret of their aircraft, the pilots must decide what to preserve, whom to trust, and who they wish to become.
