In 2055, Daemon monsters breach the veil and threaten humanity's survival. Only Demigods blessed by the Celestials can stand against them—warriors granted divine power to fight the darkness consuming the world. Azrael Mortis seemed destined for greatness. Chosen by Thanatos, the embodiment of death itself, he possessed exceptional combat talent and relentless determination. Yet a tragedy at age one destroyed his God Aspect, the very power needed to battle Daemons. His dream of becoming the strongest seemed forever shattered. Until Thanatos offered him a choice. The god of death extends a dangerous hand—absolute power in exchange for his humanity. Azrael must accept a dark bargain: wield Thanatos's blade and become the Angel of Death, transcending human limitations to achieve the strength he's always craved. "I do not give out opportunities lightly, Azrael. I shall only present you with my hand once, and never again. Take my blade and become my Angel of Death, and in exchange, I shall give you power. All the power you ever wished for and more. Power beyond your wildest dreams. What is your answer?" "I don't care what I have to do. If I can become stronger, I would even sell you my soul." "Then may this oath be witnessed by the River Styx. From this moment forward, you shall be known as Azrael, the Angel of Death."
