In a world where living beings were always born with unique abilities, allowing easy civilization and destruction. These abilities were trained to further help the development of countries and their lives. Years later, a outbreak of these abilities occurred. Using abilities now has a risk of their abilities taking control of them, turning them into demons. Oblivious to this, half of the world civilization disapeared.Six years later, these abilities were now referred to as curses. These curses was now maintained properly and used to defend the rest of human's civilization. However, it was not the same for Zaki. Zaki hates this society. Instead of trying to save those who turned into demons, they kill them to protect themselves.
