Jinwoo is alarmed to learn about the timeless war between the Monarchs and the Rulers―a war that, according to the King of the Giants, will soon rage on Earth. To complicate matters, the world’s third-strongest hunter is found dead, and Jinwoo’s father is the primary suspect―despite having been lost to a gate ten years ago!

Little do they realize that setting foot in America means crossing paths with Dongsoo Hwang, who has a bone to pick with Jinwoo about the death of his brother―and isn’t above using Jinho as bait!
