A quick review of the smash hit game Azur Lane
The story begins with the formation of a military union named Azur Lane by several nations in order to defeat Sirens, enemies that appear at the sea. Although the union succeeded in defeating their enemy, different ideologies lead to a military conflict between the opposing faction Red Axis and Azur Lane. The plot becomes more complicated when Sirens, the enemies that aren't supposed to still exist, begin their movements underwater once again.
There are many factors that make Azur Lane popular in Japan as well, for instance, the girls have unique personalities, the way they move around in the sea is entertaining to watch, and many other characters with realistic personalities also appear in this game.
