Once, there existed a group of people called the “Ih-Meh Mang Liang,” who sought to rule the world. They were infamously known to have the character “Gwi (demon)” tattooed somewhere on their body. But these people are not merely of legend… Mu-Sang is a ruthless warrior with the single mission of eliminating every Gwi he comes across. With the power of his sword “Pa-sweh” that can cut through anything, there seem to be none that can stand in his way. But what reason could Mu-Sang have to kill Gwi...when he has the mark of the Ih-Meh Mang Liang as well...!?
