Waking up underneath the sea in the body of a pony mixed with a world war 2 warship was defiantly not how the newly named Yamato thought her morning would go. But since it did, she was going to find just what had brought her to this foreign land and fused her with a ship. Now she and three thousand members of her crew prowl the Oceans of Equis, intent on finding the rainbow light that seemingly brought her here. But Yamato's return has stirred up the ocean floor, and creatures never before seen rise from the Abyss to claim the oceans as theirs.

Will Yamato wield her cannons in defense of the innocent life of Equis? Or will she turn her 18' turrets on those who would prevent her from returning to her previous life? One things for sure, those who underestimate the might of Yamato will know the fury of greatest battleship ever built. (Kancolle Kantai Collection/MLP crossover/SI, not anthro)
