Mercenary Enrollment

Mercenary Enrollment (also known as Teenage Mercenary) is a South Korean action manhwa written by YC and illustrated by Rak Hyun, serialized on Naver Webtoon since 2020. The story follows Yu Ijin, a teenager who, after surviving a tragic plane crash and spending years as a child mercenary in a foreign war zone, returns to South Korea to reunite with his remaining family and live a peaceful life. However, adjusting to normal school life proves difficult as his combat instincts, emotional scars, and strong protective nature clash with the everyday challenges of being a student. With a blend of gripping action and emotional depth, the series explores how someone forged by violence navigates love, friendship, and loyalty in a world far removed from the battlefield.

Visually, Mercenary Enrollment is marked by clean, dynamic fight sequences and expressive character design that balance intense combat with quiet moments of reflection. Yu Ijin’s calm but intimidating demeanor contrasts with the often chaotic and threatening world around him, especially as he faces school bullies, corporate corruption, and hidden enemies from his past. As the story progresses, the manhwa dives deeper into themes of trauma, responsibility, and the price of survival, while building a cast of complex allies and adversaries. With its steady pacing, strong character arcs, and high-stakes tension, Mercenary Enrollment has become a standout in the modern action genre.
