About Shin Angyo Onshi

This series takes place in the fictional land of Jushin, modeled after feudal Korea. In Jushin, there once lived secret government agents called the amen osa (or angyō onshi in the Japanese version), who traveled the countryside in disguise. They were charged by the king with finding and punishing corrupt government officials, and bringing justice to the country's citizens. The story follows the adventures of one of the remaining amen osa, Munsu, as he continues to wander the countryside and deals with the chaos caused by Jushin's fall.
