South Azur Airlines is an airline operating at the Republic of Saromo, an island nation at the Caribbean and former Dutch colony. The airline is popular for still flying the Antonov An-2, the first aircraft it acquired during the era of the nation's socialist regime, and now uses it for tourist flights around the island and surrounding Caribbean nations. One day, while taking part in an international airshow to celebrate the airline's 45th anniversary, the pilots, lead by Captain Dimitru, decide to perform a low level flyby with all the aircraft as part of the show's finale. As soon as they reach the coast and prepare to turn around for a second flyby, the fleet is caught in a geostorm that interferes with their electronic systems which shuts down the radars and navigation systems. When communication is finally restored between the aircraft, the pilots are shocked to witness a battle between two fleets of old warships and air forces. Soon, the pilots realize that they are no longer in their universe, and the storm has transported them to some sort of WW2 alternate universe. Now trapped in this world, Captain Dimitru and his pilots decide to land in the Azur Lane Base, arming their jets and flying for the Azur Lane warships, which to their surprise, can take the forms of young girls. How will the presence of the modern jets and their pilots affect the war effort of both sides? Note: South Azur Airlines is not related to the real-life Russian Azur Air company or the defunct German Azur Air.
