The story is set in a fictional Germany and centers around the outbreak of bio-mechanical creatures named "Demoniacs", who rise from corpses and attack people mindlessly. All the while, a number of human-turned-Demoniacs appear. Some use their powers for good whilst others for evil. One will rise above all other Demoniacs to become the "Blassreiter".
