It’s 2039 and the sea has expanded, claiming more land than ever before due to global warming.

As if responding to the rise in sea levels a mysterious new enemy rises with it going by the name “the Fleet of Mist” and claiming the oceans to be their own. One of the submarines from this Fleet of Mist is found by young cadet Gunzo Chihaya who becomes the first ever commander to an enemy submarine and giving humanity the first chance it’s had to fight back since the beginning of the conflict.

This is a great anime to watch whilst waiting, mainly because the theme is so close to that of Aldnoah except it takes place in the sea instead of in space. The enemy is humanoid in nature and it’s a battle for earthly resources.

The animation is a bit different, being more CGI than drawing but it’s refreshingly done, and the sequencing is incredible. Definitely worth a view!
