Solo Leveling is a story about the weakest hunter Sung Jin-Woo and his quest to become the strongest, S-Rank hunter.
After the appearance of portals known as “gates” connecting the world of monsters to humans, a small portion of the population has acquired superhuman powers to defend against the monsters. The protagonist of the story, Sung Jin-woo, is a member of the lowest rank of hunters and is the weakest hunter in all of South Korea, barely stronger than a normal human. One day, he and some other hunters find themselves trapped in an extremely dangerous and rare dual dungeon, and only a few of them survive and manage to escape. Sung Jin-woo himself “dies” but manages to complete all the trials in this dungeon. He then wakes up in a hospital and finds he has turned into a reawakened “player” who can now see an interface showing him quests, stats, inventory, store, and levels, along with the unique ability to grow exponentially stronger. Sung Jin-Woo begins on a quest to become the strongest hunter in the world and uncover the mystery of the world of monsters.
