After ten years of surviving the harshest battlefields on the planet, I-Jin Yu is finally back home. For a former child mercenary who lived through a plane crash and a decade of constant warfare, a peaceful life in South Korea is the ultimate culture shock. He just wants to reconnect with the grandfather and sister he thought he lost forever, but the halls of high school are a different kind of war zone. Between power-tripping bullies, arrogant heirs, and shady underground figures, I-Jin quickly realizes that the lethal skills he used to survive the trenches are exactly what he needs to protect his family. He is not just another student; he is a professional operator in a world of amateurs. The real question is not whether I-Jin can handle the drama of senior year, it is whether the people who cross him can survive his ruthless brand of justice. Prepare for an adrenaline-fueled ride where the quietest kid in the back of the class is actually the most dangerous man in the room. This is Mercenary Enrollment, and school is officially in session.
