翠星のガルガンティア Suisei no Garugantia

Gargantia on the Verdurous Planet (翠星のガルガンティア Suisei no Garugantia?) is a Japanese anime television series produced by Production I.Gand directed by Kazuya Murata, and aired between April and June 2013.

Plot

In the distant future, mankind has taken to the stars and formed the Galactic Alliance of Humankind (人類銀河同盟 Jinrui Ginga Dōmei?). The Alliance is engaged in a perpetual war with a tentacled alien species known as the Hideauze (ヒディアーズ Hidiāzu). 16-year-old Ensign Ledo is a soldier in the Galactic Alliance, piloting a Machine Caliber (マシンキャリバー Mashin Kyaribā), an AI-automated, humanoid-shaped battle suit, which he refers to as 'Chamber'. After a failed attempt by the Alliance forces to destroy an enemy super-weapon, Ledo is knocked into a wormhole and loses consciousness. When he awakens, he learns from Chamber that he has been in cryo-stasis for 6 months while his wounds were healing. Ledo learns that he and Chamber have been 'found' by a rag-tag band of 'primitive' human scavengers. Ledo quickly discovers that he is on board a massive fleet of ships on an ocean-covered planet. Chamber tells him that local star charts reveal the planet is Earth, the birthplace of humanity, a place that members of the Alliance were only familiar with from stories and believed was a myth.
