I promise I won’t be posting OPs every time I do a review, but Gargantia‘s does such a good job of sonically explaining the whole show in the first 20 seconds of the song that I just had to post it. The song sounds just like the setting looks, and unity of that sort is always impressive.
So, a quick plot summary: A space soldier named Ledo and his incredibly advanced robot suit/companion Chamber get knocked out of the galactic battle for the survival of humanity and wind up on Earth. However, this isn’t the Earth you know. There’s no land left. The entire planet is one huge ocean, with the remnants of the previous civilization resting at the bottom of it. The current inhabitants live on fleets of interlocking ships, where they grow their food, work and live their surprisingly beautiful lives. This isn’t your typical post-apocalyptic world; but a world whose people found a way to survive and now live pretty awesome lives. And when you see how beautiful the land…erm, ocean…they inhabit is, you’ll understand why.
