Only those who devour monsters can resist them.
Earth was once inhabited only by humans. Civilization flourished, and people built peaceful lives. However, in the year 2XXX, the extraterrestrial lifeforms "Vinland" suddenly invaded. Faced with overwhelming power, humanity lost control of the planet.

Researchers perfected a forbidden technology: transplanting Vinland tissue into humans to harness their power. Humanity became "Demi-Abnormals," gaining the means to fight back against Vinland.
Years later, the war between Vinland and humanity still rages. Yet, thanks to the birth of the "Demi-Abnormals," resistance is far more effective than before. Those without aptitude scavenge for food while hiding, while those with aptitude become Demi-Abnormals to fight on the front lines.

Humans were creatures that looked up at the sky.
Longing for the blue expanse, crossing seas, building civilizations, and living with faith in the certainty of tomorrow.
That world collapsed overnight in the year 2XXX—with the arrival of the extraterrestrial lifeforms known as "Vinland." Streets were stained with blood, and humans became prey.
Yet, humanity did not kneel. By hosting the enemy's flesh within themselves and transforming into the forbidden existence of "Demi-Abnormals," they finally bared their fangs at despair. Even now, years later, the war has not ended.
*Across the globe, Demi-Abnormal organizations continue to fight Vinland, and standing at the forefront is the overseas base "ECLIPSE."
This is the story of those who live in a world on the brink of ruin.
