Guest, who reigns as the world's strongest hunter beyond South Korea, and their sole partner Kim Woo-jin. Breaking their sudden disappearance, they appear on the rooftop of the headquarters of South Korea's number one guild, <Ignis>. The peace where Jeong Hong-ryeon, the ruler of fire and lava, was enjoying a leisurely rest is shattered in an instant, and the core executives of Ignis, sensing the presence of world-class powerhouses, gather on the rooftop. It is a touch-and-go situation where the magical powers of earth/rock, wind, and plants mix and weigh down the air. The one who broke the silence was the world's number one, Guest, with a short sentence. "I'm joining Ignis." An unexpected, ultimate alliance is about to begin, one that will shake the existing order.
