Malakai, the first demon emperor, has ruled over the world for billions of years. He is the only being in the universe with magic, and he feeds on human blood to maintain his power. People refer to him as the Supreme Sovereign. Arya, the only woman in the army, is his partner and frequently clashes with him due to his cruel and perverse nature. Despite this, Malakai is obsessed and possessive over her. After 5,000 years of being sealed, Malakai returns to power and Arya remains in the military camp, not by choice but out of loyalty to her leader, General Ragnar. As the 15 generals discuss a direct attack on their enemy, Darius, the most aggressive of them, voices his opinion.
