The Z-class destroyers, a group of destroyers that makes up most of Ironblood's destroyers, they vary wildly from each other all having their own personalities and strengths. However, nearly erased from history, because of its unorthodox method of battle, the Z-73, the lead and only ship of its class, was a monster of the ocean. No songs are sung of it, only legends. The ship seems to be a phantom amidst the war, attacking in storms to disoriente and decimate its foes, even fighting the likes of Hood without so much as a scratch. Earning the feared name "Blitzmeister" Being laid down at the end of the war, the story was never told, but now, awoken once again in the world of ship girls, she shall demonstrate why she is called the Lightning Master.

5 individual worlds. 5 different ships, all having gone through challenge after challenge. 5 different paths...all converge onto one. When a threat that is both familiar and oh so distant makes itself known, they will need each others help. Yet the secret fell out, they need to travel to more worlds to loosen their foe's hold on domination. That's something they are more than willing to do. Something that they must do. Or they will all fail.

Hunger can change people, but hunger is controllable when you know what to do. True starvation however, leads to dangerous things, death being the worst. Or was it?

The Golden Queen... The one who felled Kulve and donned her armor... The one who saved us from the Blazing Black Dragon... The one who turned Raging Brachydios into her blade... and the one who met her match in Fatalis... in a bit of an... unexpected turn.

A derelict and broken ship. Cast to death for a complete misunderstanding. Her old allies, hoping to locate her corpse to at least give her a proper burial. The deep Brine she has been corroding in for years, in the dark depths of the ocean. The Trench, the entrance of the Abyss...it calls her name, it welcomes her into its grasp. "Welcome to your throne, o great queen of the Abyss"
