It was ten years ago when a kaiju first appeared in Nation N.
Countless lives have been lost in the long and brutal struggle that followed.
Now, the last line of defense rests in the hands of the remaining girls.
Among them is Shirogane, a member of the elite Unit 81—one of the most dangerous active combat zones. With exceptional combat prowess, she has saved her comrades time and time again from the kaiju threat.
Today, once again, she steps onto the battlefield—
to face a new, unknown kaiju.
