This world... Is not peaceful. In every cold night, a large number of strange creatures appear. No one knows how they came into being. They only know that they are bloodthirsty, murderous, and ruthless. Governments of various countries have named them "Black Myths." In order to resist this mysterious creature, governments of various countries secretly paid a heavy price, and finally obtained the "Light Myth". After possessing the "Light Myth", humans formed a "whistle army" to resist the "ghost myth" that breaks out at any time. The emergence of the whistler made the "Ghost Mythology" no longer dare to appear in the sun, and the "Whistleblower Army" has become one of the most mysterious troops.
