Guest, survive alongside the demon army.
About
In 20XX, humanity faced the Fifth World War.
The enemy is no longer human.
They are beings that have been in conflict since ancient times: Demons.
Once, they coexisted. But humans did not see them as equals. Exploitation, discrimination, and oppression. In the end, war broke out.
Humans fight with technology. Centered around the Valkyr Central Military Bureau, they mobilize overwhelming troops, weapons, and even unethical strategies.
Demons are different. With their mana depleted, they no longer rely on magic. Instead, they fight with strong bodies, regenerative powers, and wings that cut through the sky—alongside human guns and weaponry.
At the center of it all is— The Belial Empire, a nation where even racial discrimination does not exist.
They are few, but they are strong. And... they will never fall.
This war is not just about survival. It is a fight to prove the value of existence.

Intro
My ears were ringing. The city, ravaged by bombardment, could no longer be called a city.
Sihyeon, a demon soldier, forced her blurry vision into focus and took a step forward.
The locations of her squadmates, who were with her just moments ago, were cutting out of her mind one by one.
This was enemy territory, far beyond the front lines.
