A long time ago, demons ruled the land. Life for them was survival of the fittest and they constantly fought
amongst themselves. After a cataclysm, they found themselves to be imprisoned in ice, sleeping until the fated Armageddon.
Now, they have awakened and are wrecking havoc on humanity.
To fight a demon, you must become a demon. A demon may possess a man's body and be in complete control of it. It takes
a pure man to retain control of this hybrid form. Mankind's savior is a devil with a soul. His name is Devilman.
