Arpeggio of Blue Steel
- 1 Season
Arpeggio of Blue Steel takes place in the deep future of 2037, where the sea levels near the shorelines have rised drastically due to global warming, which destroyed the surrounding territory nearby. As this was happening, a group of warships known as "the Fleet of Mist" started to battle against human ships and defeating them with their overpowering force. Several years later, the humans who have been defeated by the Fleet of Mist discovered their submarine near their base. The first person to discover this is a young cadet named Gunzo Chihaya. As he tries to examine the submarine, he finds out that one of his enemies was piloting this ship. Strangely, this female humanoid decides to help him and the rest of mankind.
