Blade of the Phantom Master (Japanese: 新暗行御史, Hepburn: Shin Angyō Onshi; 'New Secret Royal Agent') / (Korean: 신암행어사; RR: Sinamhaengeosa) is a South Korean-Japanese manga series written by Youn In-wan and illustrated by Yang Kyung-il. The story takes place in a world reminiscent of ancient Korea, and follows the Korean-folktale-inspired adventures of Munsu, one of the few remaining guardians against corruption and tyranny, as he seeks to find those responsible for the destruction of his country. It was serialized from 2001 to 2007 in South Korea (as Shin Amhaengosa) and in Japan (as Shin Angyō Onshi), and was adapted into an anime theatrical-release film in 2004 in a first-of-its-kind collaboration between Japan and South Korea.
