A Story Between Warship Girls R and Azur Lane

(Abandoned) There was once a great war between Fleet R and Azur Lane. That war directly led to the Second Deep Sea Invasion. People learned their lesson, but the United Fleet split apart, forming the Eastern Alliance and the Western Union as the headquarters of Fleet R and Azur Lane. Many years have passed since that war. An old veteran hopes his grandson can find the ship girls he once knew and apologize to them on his behalf.
