A Quick 411 on the Jeju Island Arc
In the original Solo Leveling manwha, the story opens right as Sung Jin-woo is facing certain death in the Double Dungeon. However, the anime chose to start things off differently. Instead, it begins with a scene on Jeju Island, where a group of Hunters is fighting for their lives against Monsters. This original scene was the first of several added throughout the anime, most of which would revolve around Jeju Island. There’s a very good reason for this: it’s the anime’s way of building up to one of the most important arcs in the entire story. And if you’re reading this, it means that the anime is making that arc into its season finale and not giving it the Demon Slayer: Mugen Train treatment or theatrical release, much to my dismay.
Personal feelings aside, this is meant to serve as a quick summary of what makes Jeju Island such an important location in Solo Leveling. And why what’s about to happen is going to be a speedrun of Hunter x Hunter’s Chimera Ant Arc on steroids.
Four Years Earlier…
The story begins four years before the events of Solo Leveling. An S-Ranked Dungeon spawned on Jeju Island, the largest island in the Korean Peninsula, forcing Hunters to attempt to close it. However, due to it being the strongest possible Dungeon, and how weak Korea’s S-Rank Hunters were back then, they failed to close it in time. As a result, it underwent a Dungeon Break, AKA what happens when the Monsters inside can spill over into the Human world. In this case, it was legions of ants the size of your average human being, if not bigger.

Thousands of people ultimately died at the monstrous mandibles of the insects, and the Hunters and Korean Government were powerless to stop them. All they could do was get everyone left alive and get them off the island before they met the same fate. Thus, Jeju Island was left abandoned, a wasteland devoid of any human life while its buildings served as an eerie monument to the Hunter’s failure.
And the ants were free to multiply and make the island their own kingdom. But Korea wasn’t going to sit back and let things remain as they were.
Three Years of Failures
Over the course of the next three years, the Korean Government and its top Hunters made repeated attempts to take back the island. To say that they proved disastrous would be an understatement. Their third and latest attempt not only failed, but it cost the life of one of their S-Rank Hunters. Baek Yoonho, Guild Master of the White Tigers, had to watch as that man died and couldn’t do anything about it! And their mutual friend was so traumatized that he quit being a Hunter altogether!
After that failure, the Korean Government decided they couldn’t afford to risk more lives, especially with how few S-Rank Hunters they had. So, they decided to leave the island and its ant masters alone, hoping that once they ran out food, they would either starve or turn on each other.
It didn’t work.
The Chimera Ant Arc on Steroids
The Ant Queen that served as the Dungeon’s boss wasn’t a mindless beast; she was intelligent. Intelligent enough to realize that if things remained as they were, her children would die. Unfortunately, that meant evolution kicked into overdrive. The newer generations of ants started being born with wings and the ability to fly. Slowly but surely, the first scouts started making their way to the surrounding nations, all of them full of humans and animals upon which they could feed.
In other words, if those ants aren’t taken care of now, then they would overrun Korea, Japan, and even China. And the rest of the world could be next.
The earlier comparisons to the Chimera Ant Arc from Hunter x Hunter weren’t hyperbole. Both center around fighting a colony of incredibly powerful, super-intelligent ants. If left unchecked, said ants could spread enough to conquer the world and turn humankind into its food source. And if that wasn’t scary enough, the Hunters of each story have to face an opponent that is beyond their worst nightmares. The only difference is that what’s about to happen in the Jeju Island Arc is going to be speed-running through the entire story and look far cooler doing so!
Regardless of whether the Jeju Island Raid Arc is a movie or just the season finale, the coming battle will be Solo Leveling’s biggest to date. It’s the kind of battle that will make even the internet-breaking feats of Jin-woo vs the High Orcs look tame. For a series that seems to thrive on serial escalation, that should not be taken lightly! So make sure you are prepared and have snacks ready. You will need them!
