About 30 years ago. "Gates" suddenly appeared all over the world. Black doors that looked like cracks in the air. At first, no one knew what they were.

However, not long after the gates opened, monsters beyond human common sense began to pour out of them. Guns and armies were not enough to deal with the monsters. Cities collapsed and countless people lost their lives. People call that day

"The Day of Catastrophe"

And after the gates appeared, special changes appeared in some humans.

Powers that work even against monsters. Abilities that exceed human limits. People began to call them "Awakeners."

Gates occur randomly all over the world. Inside the gate, there is a space different from reality. People call that place "Dungeons."

Various monsters exist in the dungeon, and a powerful boss monster exists in the center.

When the boss is defeated, the dungeon collapses and the gate disappears. However, if it is not cleared within a certain period of time, "Gate Break" occurs.

The monsters inside the dungeon pour out into the real world.

When a Gate Break occurs, an entire city can disappear.

Therefore, hunters must enter the dungeon and clear it whenever a gate is discovered.

Hunter Among the Awakeners, those with special abilities work as hunters. Hunters make it their profession to clear gates and hunt monsters.

There are a total of 6 hunter ranks.

F-Rank A level slightly stronger than an ordinary person.

E-Rank A level capable of dealing with low-level monsters.

D-Rank A level capable of clearing small-scale dungeons.

C-Rank A level capable of participating in clearing mid-level dungeons.

B-Rank High-ranking hunters.

A-Rank Top-tier hunters specially managed by the state. And there is only one rank above that.

S-Rank An S-Rank hunter is a being who can overturn a nation's military power alone. Only a very few exist in the entire world, and the mere appearance of one S-Rank hunter becomes global news.

World Hunter Ranking S-Rank hunters cannot be judged by rank alone. Therefore, the World Hunter Association operates a separate World Hunter Ranking. Rankings are determined by synthesizing combat power, dungeon clearing ability, and Gate Break suppression records.

Hunter Association An organization that manages hunters and gates around the world. It is responsible for controlling gate occurrence areas, hunter registration, dungeon clearing permits, and monster research. In South Korea, there is the Korea Hunter Association. However, the association is not very important to Han Sion. As the world's No. 1, he has no obligation to follow the association's orders, and even most executives cannot dare to order him around.

Monsters Monsters are creatures that appear from gates and dungeons.

There are various types, from relatively weak monsters like goblins or wolves to disaster-level monsters that can destroy an entire city. Monsters generally do not understand human language. However, some high-level individuals have intelligence similar to humans, and there are also sentient monsters capable of conversing with humans.
