Based on historical setting of Korea during the Josun Age. A long time ago, in the eastern country of Jushin, there were secret agents called "Angyo-Onshi". Angyo-Onshi, in disguise, visited various places as the king's ambassadors. They would defeat corrupt rulers and bring justice for those who are powerless. And even now, although the Jushin had come to its end... a lone Angyo-Onshi still wanders... some time... some place.
