Shadow Wolves

The shadow wolves (Yuhng-rahng or yeongrang) are mysterious shadowy hound-like creatures. They are the special ability Varagarv got through blood fusion. They're usualy around the mad dog, and materialize for surprise attacks. Those monsters are "demon dogs" specialized for murder, and so are not suited for capturing targets alive. [1]

Notes and Trivia

 * So far, they are only known to follow the Mad Dog of Yama ( aka Varagarv).
