After the Earth was destroyed by mysterious alien lifeforms known as the Gauna, surviving remnants of the human race escaped to space in the enormous generation ship Sidonia. Having drifted through space for millennia, the Sidonia found itself once more under attack from Gauna for the first time in a century. Once again facing the threat of extinction, a temporary victory against the Gauna was eked out thanks to the human-Gauna hybrid Tsumugi Shiraui and ace Guardian mech pilot Nagate Tanikaze. 10 years later... The people of Sidonia enjoy a brief respite. Peaceful days pass, during which Tsumugi begins to realize her feelings for Nagate, who is now celebrated as a hero of Sidonia. However, as Captain Kobayashi has always known, as long as the Gauna remain, peace cannot last. The decision is made: a final battle, upon which rests the fate of humanity's last survivors. As the end approaches, will the crew be able to protect those they love?
