Knights of Sidonia

Humanity’s last vestiges cling to survival aboard the colossal generation ship Sidonia, fleeing a devastating war against the inscrutable, shapeshifting alien known as the Gauna. Centuries after Earth’s destruction, a new generation of genetically engineered pilots, capable of wielding giant mechs called Gardes, represents mankind's only hope against extinction. This desperate struggle for existence is a daily reality, where every sortie into the void could be a pilot's last. As new recruit Nagate Tanikaze emerges from the ship's forgotten lower levels, his natural piloting talent quickly thrusts him into the forefront of this unending conflict. Navigating the rigid, sometimes brutal, social structures of Sidonia, Nagate must confront not only the terrifying Gauna in visceral, high-stakes battles, but also the complex ethical dilemmas that arise when humanity is pushed to its absolute limits.
