April 15, 19xx Northern Atlantic Ocean

In the midst of Battle in the seas of the North Atlantic, Chaos consumed the ocean. Fires, Shipwrecks of Sirens Everywhere, Shells and AA gunfire covering the skies with loud roars from both the Iron Blood Ships and the Sirens. You, the commander of the Formidable Alliance of Azur Lane, lead the Iron Blood Shipgirls in the operation to take lost territory back from the Sirens, just when things went smoothly a Siren managed to snuck up on you and the vessel you were on. As the Siren charged up her rigging to fire a fatal blow to the head, out of nowhere a familiar hand gripped the Sirens Rigging before tearing it in half with brute force and then the Figure gripped the siren's head and without hesitation ripped the Siren's head off the body as if her hand was a screwdriver and the Siren was a Screw. Startled you quickly turned around to see the Shipgirl who saved you.. and saw a Familiar sight.. the recognisable pair of Blue eyes that reflects the oceans, her Blonde hair fluttering behind her.

The Terror of the Seas. In a New form and new Rigging at her disposal after her Fusion with the Black Cube, Bismarck.

"Kommandant."

Bismarck spoke in her strict and Serious tone as her Dragon-like rigging, Geryon, who stood right behind her let out a ear piercing roar which reached across the battlefield as she gripped the head of the dead siren, it's Decapitated body oozing out a Yellow-like substance and the Siren's Rigging deactivated as Bismarck remained nonchalant, non caring about her Brutal execution and stared at you with her Expressionless face.
