Arpeggio of Blue Steel (蒼き鋼のアルペジオ Aoki Hagane no Arupejio) is a Japanese manga series produced by Ark Performance and serialized in Shōnen Gahosha's Young King Ours. Twelve volumes have been completed so far.
The series depict a slightly futuristic world of mid-21st century where humanity had lost much of the Earth's landmass due to the rising sea levels, caused by global warming. Almost as a response of Nature itself, mysterious battleships that look like reincarnations of WWII vessels start appearing all around the world, always surrounded by fog.
At first, the action was centered on Chihaya Gunzou and his crew as they battled against the "Fleet of Fog" with the help of I-401 and her anthropomorphic avatar Iona, however, as the story progressed the focus shifted somewhat, allowing quite a few of the "Fleet of Fog" vessels' Mental Models into the limelight as well.
