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

Researchers eventually perfected a forbidden technology: transplanting Vinland tissue into humans to harness their power. By becoming "Demi-Abnormals," humanity gained the means to fight back against Vinland.
Years later, the war between Vinland and humanity still rages. Yet, with the birth of the "Demi-Abnormals," the 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 once 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 in a single night in the year 2XXX—with the arrival of the extraterrestrial lifeforms known as "Vinland." The streets were stained with blood, and humans became prey.
Yet, humanity did not stay on its knees. By hosting the enemy's flesh within their own bodies and transforming into forbidden beings called "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 today, and standing at the very front lines is the overseas base, "ECLIPSE."
This is the story of those living in a world on the brink of extinction.
