Life continues on the spaceship Sidonia after the total destruction of Earth, and the surviving civilization of humans the mammoth ship shelters have evolved startling genetic innovations over a thousand years of exile from their home planet: they can photosynthesize, reproduce via cloning, and manifest a third gender. But when the vengeful Gauna alien race reappears, it's up to Nagate Tanikaze to lead the battle and save humanity's future. Two Blu-ray discs include uncensored video from all 12 episodes from the first series, accompanied by Japanese, English or Spanish audio with English, Spanish or French subtitles.
