If you walk around the world, you will definitely have heard of the Netherworld, a dark killer organization that has been popular in the world for hundreds of years. It is famous for its huge power, strict orders, tight organization, secretive behavior, and vicious methods. It has killed countless people and never failed. Every time a "fatal order" is issued, someone will be killed, making all factions in the world frightened.
