A History of Disaster: Jeju Island’s Past
Four years beforethe main Solo Leveling storyline events, an S-Rank Gate appeared on Jeju Island. This gate opening marked the beginning of a series of devastating raids that would leave a lasting negative impact on the island and its poor inhabitants caught in the crossfire. The initial attempt to conquer the dungeon within the Gate ended in catastrophic failure, resulting in a Dungeon Break thatunleashed hordes of monstrous large antson residents of Jeju Island.
Despite multiple attempts by the Korean government to reclaim the island, every raid proved unsuccessful. One such raid on Jeju Island resulted in the tragicdeath of a top S-Rank hunter, Eunseok. The loss of such a powerful hunter demoralized the Hunter Association and forced them to retreat from Jeju Island. They thought the ants would stay trapped on the island since they could not fly or swim. This tragic event weighed heavily on Choi Jong-In, who led the third raid, leaving him with a deep sense of survivor’s guilt and a burning desire to redeem himself.

This is where the story of the popular anime series begins with the introduction of our beloved E-Rank hunter – Sung Jinwoo – in the current timeline.
Basic Understanding of How Raids Work in Solo Leveling
In the world of Solo Leveling, Gates serve as portals to dungeons that house a variety of monsters and magical beasts. These dungeons are classified by rank, from E to S, with S-rank dungeons being the most challenging. Hunters, individuals who are awakened with supernatural abilities, are tasked with raiding these dungeons to prevent Dungeon Breaks and protect the humans from these monsters.
Hunters are also classified into six main types:Fighter, Mage, Assassin, Tanker, Ranger, and Healer. Each type possesses unique strengths and weaknesses, and a balanced team composition is crucial for successful dungeon raids.

The Rise of the Ants: Evolution and Flight
Meanwhile, left unchecked, the ants continue to multiply and evolve on Jeju Island. As their numbers grow and as resources on the island get depleted theybegin to develop wings, driven by the need to leave the island and seek sustenance elsewhere. One of the ants eventually makes landfall killing and injuring a few civilians. This forces theHunter Associationto organize a fourth raid, this time with the assistance of Japan’s strongest guild, the Draw Sword Guild, led by the formidable Goto Ryuji.
The Fourth Jeju Island Raid: A Desperate Battle
The fourth Jeju Island raid was a desperate attempt to eradicate the ants before it could spread further. The plan involved the Japanese S-rank hunters acting as bait to draw out the ant drones while the KoreanS-rank huntersfocused on eliminating the Ant Queen and her Royal Guards.
Initially, the plan seemed to be working. The Japanese hunters effectively lured the ants away, and the Korean hunters successfully located and killed the Ant Queen. However, the situation took a drastic turn with thearrival of the Ant King, an incredibly powerful magic beast that quickly decimated the Korean hunters.

This devastating encounter resulted in thedeaths of eight S-Rank hunters, including some of Korea and Japan’s most formidable hunters. The table below lists all the hunters who lost their lives in the Jeju Island raid:
Adding another layer of complexity to this international collaboration was the hidden agenda of the Japanese hunters. Their participation in the raid was partly motivated by adesire to weaken South Koreaby reducing the number of S-Rank hunters. This ulterior motive foreshadows potential future conflicts and highlights the political tensions that underlie the seemingly cooperative effort.

Despite being invited to participate in the raid, Jinwoo initially declined, choosing to stay with his mother who had recently awakened from a coma – thanks toThe System. He was also concerned about the well-being of his sister and hesitant to leave his family while they were still adjusting to his mother’s return.
However, upon sensing the escalating danger and the deaths of his fellow hunters,Jinwoo decided to join the fight. His arrival on Jeju Island marked a turning point in the battle. With his overwhelming strength andShadow Army, Jinwoo single-handedly dominated the Ant King, ultimately defeating him and saving the remaining hunters.
This victory showcased the stark contrast between Jinwoo’s unique ability to level up and the static power levels of most other hunters. While other hunters are limited by their initial rank and abilities, Jinwoo’s potential for growth is limitless, making him a crucial asset in battles like the Jeju Island raid.
