Knights of Sidonia

Knights of Sidonia is a sci-fi mecha TV anime adapted from the manga by Tsutomu Nihei, produced by POLYGON PICTURES under the direction of Kobun Shizuno and series composition by Sadayuki Murai. Set aboard humanity's last surviving seed ship, the series follows Nagate Tanikaze as he battles the alien Gauna alongside companions like Izana Shinatose and Shizuka Hoshijiro. Rendered entirely in CG animation, the series delivers visceral space combat and a richly atmospheric dystopian world that stays true to Nihei's original vision — a must-watch for fans of action-driven mecha and hard science fiction.

A thousand years have passed since a mysterious alien species known as the Gauna obliterated the solar system, leaving humanity on the brink of extinction. The survivors fled aboard massive vessels called seed ships, with one such craft—the Sidonia—continuing to drift through the vast darkness of space, sheltering what remains of the human race. Nagate Tanikaze is a young man who grew up in near-total isolation, hidden away in the deepest levels of the ship, far removed from the society living above him. When he finally emerges and begins training as a pilot of the towering mechanized weapons called Gardes, he finds himself at the helm of Tsugumori, a legendary unit steeped in history. Now thrust into the frontlines of a war against an enemy that defies all understanding, Nagate and his fellow pilots must confront the Gauna in a desperate struggle to ensure humanity's survival.
