She was not able to control several thousand tons of steel with her mind. Most importantly, however, she was NOT okay with this insanity!

An AU set in the present where the Sirens won and the long since reunified Azur Lane Alliance fell before they could deploy their 'Shipgirls'. The hero of this story isn't some war veteran or even a member of Azur Lane; he's just some random guy who just got lucky, that's it.

In the seas between the Isle of Patch and Vale, there were hushed whispers of a Great War Era Battleship still sailing around.

The official report was that he was shot down over Zhytomyr, but that isn't the case. The main part of our story takes place in the far away world, a world different from mine or yours, a world where people give logic, science, gravity, and basic physics a big fuck you. This is the world of Azur Lane. The Russians haven't shot him down, he is just fighting other demons.

Some years after Ulysses 1994XF04, Erusia had taken control of Stonehenge and used it to take control of the skies and dominate the continent of Usea. The Sirens take full advantage and discover two new pilots for their project…

A foolish attempt to keep power summons dangerous entities from another dimension. Now Izuku and others must call on the spirits of warriors from the past to fight again, against this terrifying threat.
