Azur Lane - Operation Grey Talons

The Pacific Ocean, 1941.

The ocean is calm and peaceful, the skies are obscured by white clouds, and the air runs thick with the tension of war. For years, humanity has been waging a war against an alien race known as the Sirens, whose advanced technology has allowed them to take over much of the waters of Earth and rule over it with an iron fist. In response to this threat, humanity would utilize one of the Siren's very own technologies against them: The Wisdom Cube, a mysterious cubical construct capable of making dreams and imagination into reality.

Through this cube they managed to forge the "Kansen", sentient ships from the second world war granted female humanoid bodies, capable of housing both the will of mankind and the armaments that they have forged; yet even this has not granted humanity the necessary edge over the Sirens they need, for the technological difference remains too great to surpass with just these girls.

Yet, above the waters of the Pacific, the air began to thrum with something foreign, something alien. Soon enough, a great floating citadel appears high in the sky, carrying heraldry native not to earth, but rather to an entirely different world:

Neter.

I do not own Azur Lane and From The Depths, this is just a fanfic crossover between the two with some original characters and semi-original characters.
