Arpeggio Of Blue Steel: Ars Nova - Dc

In the near future, the mysterious Fog Fleet, a faction of thinking ocean-going warships and submarines, appears on the world's oceans and declares war on mankind for unknown reasons. Many of the ships have their own personalities, so-called mental models, which can take on physical form as female avatars of their ships. Due to the superior technology of the Nebula, however, it is a very unbalanced battle and mankind has to retreat more and more. Seventeen years later the naval officer cadet Chihaya Gunzo awakens the Fog Fleet submarine I-401 and the Mental Model Iona appears. She has the surprising mission to follow Gunzo's orders. Iona, Gunzo and his mercenary crew, the Blue Steel, take up the fight against the fog together.
