"Solo Leveling" features a world where humans have developed powers based on the concept of "Hunt." The main character, Sung Jin-woo, is a low-level hunter who was considered useless by society. However, after a near-fatal mission, he is granted the power to grow stronger every time he fights and kills a monster. Sung Jin-woo's journey from being a weak hunter to becoming a powerful "solo hunter" is filled with adventure, excitement, and high-stakes battles against powerful monsters.
