For more than 1,000 years, an organization known as the Slayers has fought against the Oni menace from the shadows. Since the large-scale emergence of the Oni ten years ago known as the Awakening, they have served to protect the realm of man and history itself from certain destruction.
The warriors that serve within the Slayers organization are also referred to as Slayers, and they possess the special ability to perform a ceremony that can purify the evil spirits cast forth by the Oni, earning them a reputation as "demons who slay demons."
