Solo Leveling is an action-fantasy webtoon written by Chugong. The story follows Sung Jinwoo , a young hunter considered the weakest in the entire Hunter community. In a world where portals open to dungeons filled with monsters, hunters are humanity's only defense. But Jinwoo, despite his determination, possesses almost no abilities and often comes close to death.

During an expedition that turns into a nightmare, he and his group find themselves trapped in a mysterious temple with deadly rules. Just when all seems lost, Jinwoo miraculously survives and receives a unique power: the ability to see a virtual interface like in a video game. Now, he can become stronger without limits, complete quests, increase his stats, and acquire new skills that no one else possesses.

As Jinwoo's meteoric rise to power unfolds, he attracts the attention of formidable enemies and forces far more ancient and dangerous than mere dungeon monsters. Seeking to understand the origin of his power, he finds himself at the heart of a titanic conflict between the Monarchs and the Rulers , divine entities who have been battling each other for millennia.
