USA is one of the notable countries in the series. The country was said to hold the most numbers of S-Rank hunters number to 50 hunters, most of which not born in USA but from other countries.
The country collected a lot of hunters from all over the world through the means of their hidden hunter Norma Selner, a hunter with the power to upgrade a hunter's abilities. Using her as bribery, strong hunters such as Hwang Dong-Su were cajoled to join the strongest American guild, Scavenger Guild or to move to USA. This move was done to Sung Jin-Woo through Adam White but for the first time, a hunter rejected their offer.
