Most Hunters in the world joined the Mercenary Association. It is the largest independent organization that is acknowledged by the Seven Great Powers.
It had its own currency and services it provides to people who hunts.
The Mercenary Association is affiliated with many other world powers as they supplied most of rare treasures and materials in the worlds.
Most of the hunters that register with the Mercenary Association would get all kinds of benefits like insurances against their death and he guarantee that their family would be provided for after their death.
It is also because of such benefits that the Mercenary Association usually give one year and a half trial period to any hunter before they are qualified to register their name into the Mercenary Association.
The Mercenary Association is given the list of the forbidden areas by the Seven Great Powers and in turn, the Hunters tell the people of the forbidden areas.
