KMS Rheinfeld Bio

Recently, there were sightings of unknown ships in the seas near Antarctica but 2 months later, those ships are now nearing the main Azur Lane base, their movements change every. Single. Day, as they get closer, and closer, to the base, will Azur lane survive the onslaught of their new enemy?

(Note: Azur Lane isn't owned by me, this story is not inspired by anything, and all image shown, aren't mine either, what i DO own is my Oc's)
