Azur Lane

Azur Lane is a military alliance formed by four countries - the Eagle Union, Royal Navy, Sakura Empire, and Iron Blood - in response to the sudden appearance of the Sirens, an alien force with advanced technology. This alliance initially led to a victory against the Sirens, but the nations soon splintered due to ideological differences. The Sakura Empire and Iron Blood broke away to form the Red Axis, re-fragmenting humanity. Enterprise, a seasoned fighter and central figure in Azur Lane, grapples with her own insecurities despite her tough exterior.
