The ship girls are in trouble, and the culprit is Yuubari, who wanted to open Pandora's Box.
The box got annoyed and flung all the ship girls into different worlds.
To get them back, the journey from world to world begins.
What kinds of worlds will the pirates of the Warship Girls R world see on their travels?
S113: I'm just a destroyer passing through. Remember that! (Pulls out a card)
Kitakami, Ooi: Now, let's count your sins~
Tashkent: Comrade Belt, come run a lap with me! (Unleashes the strongest voice of the Heisei era (not really))
Northern Princess: Watch me clear the game in one life!
Yuubari: The path to victory is already set!
Admiral: If you're going to gang up on them, hurry up! We still haven't found the rest of the people from the naval base!
This is a story about ship girls × Kamen Riders, with a trip through various worlds along the way.
And causing some trouble while we're at it.
Abyssals: The devils have finally left (muttering quietly)
