Knights of Sidonia

In a distant future, humanity clings to survival aboard the colossal spaceship Sidonia, a vessel that has journeyed through the cosmos for a thousand years since the Earth's destruction. Constantly under threat from the Gauna, monstrous alien entities bent on their eradication, the remaining population dedicates itself to an endless war for existence. A unique culture has blossomed within Sidonia's confines, where cloning, asexual reproduction, and even photosynthesis are commonplace, all serving the singular goal of preserving the human race. Our story begins with Nagate Tanikaze, a young man who has spent his life in the ship's forgotten lower levels. His unexpected emergence into the upper echelons of society thrusts him into the cockpit of a legendary Guardian, Sidonia's primary combat mecha. As he grapples with the intricacies of piloting and the brutal realities of interstellar warfare, Nagate becomes a pivotal figure in humanity's desperate struggle against an incomprehensible enemy, forced to confront the true meaning of courage and sacrifice in a world teetering on the brink.
