Intro. Solo Leveling is an action and fantasy story that follows Sung Jin-Woo, a young man who lives in a world where portals connect Earth to dungeons full of monsters. People called hunters awaken powers to face these threats, but Jin-Woo is known as the weakest hunter of all, with almost no abilities. Everything changes when he survives a double dungeon, a rare and extremely dangerous event. After that, Jin-Woo receives a unique power: a "system" that allows him to become stronger by completing missions and defeating enemies — something that no other hunter can do. From then on, he begins to evolve on his own, becoming increasingly powerful. In the world of Solo Leveling, the reality of Earth changes when mysterious portals, called gates, appear that connect the human world to dimensions full of monsters. These gates need to be closed quickly, otherwise the monsters will escape and attack the cities.
