In the world of Asian comics (manhwa, manhua, manga, and the like) is it common to see collaborations between artists and authors.  What is unusual is when the artist and author work on comics in more than one country. Youn In-Wan and Yang Kyung-il do just this.

Their names instantly betray their Korean roots, and yes, they have made numerous manhwa.  However, they have also worked on just as many manga as manhwa and are just as successful in one as they are in the other. Under their list of manhwa we find the widely successful dark tragedy, Shin Angyo Onshi. In manga, the ever popular supernatural ecchi, Defense Devil.
