Story: After the disappearance of the kingdom of Jushin, the power-hungry governors bring terror to the defenseless villagers. Only one of the secret agents of that kingdom is left, the Angyo Onshi named Mun-Su. Together with his bodyguard Mon-Ryong, he travels the country to protect the oppressed and punish the tyrants.
Art: The art of this series is very different from the usual manga series. Drawn by a korean artist, it really brings about a new scope in the art of manga. The character designs are memorable and detailed. Even a simple coat is drawn to show a huge amount of detail. The backgrounds are also detailed and intricate.
Overall: The art style is really a new insight. The difference in styles between korean and japanese art is distinct. The story buildup is also good. The story starts off simple. But the final story arc really tops the story off. A really good read for people looking for something different.
P.S. The series is already licensed, so I gotta recommend getting the book to read. If not, get a preview here.
