We plunge into a world where 71% of the world's waters have not yet been discovered in Azur Lane, the anime adaptation of the mobile game of the same name. Long ago, the Sirens, a formidable foe from another dimension attacked this earth! In order to defeat this adversary, humanity established Azure Lane, a world organization that used so-called Wisdom Cubes to give girls and young women the might of great warships. These courageous and attractive shipgirls, divided into the four camps of Eagle Union, Royal Navy, Iron Blood, and Sakura Empire, were essential to the victory over the Sirens.
But now that the conflict is done and the Sirens have been driven back, the four groups' various ideologies are at odds. The Eagle Union and the Royal Navy stand in the path of the Iron Bloods and the Sakura Empire's attempts to study and utilize the power of the Sirens. Iron Blood and Sakura Empire, who were once close partners, now depart from Azure Lane to establish the Red Axis. Azure Lane builds a new stronghold in the ocean to watch over the Red Axis' schemes out of suspicion for their erstwhile comrade.
