Bangtan Samurai

Ten years have passed since the violent events that took place during feudal times in South Korea. Times of big changes. During these events, there was a skilled, merciless and bloodthirsty samurai known as "Red". He collaborated on various murders to make way for a new government, and thus eliminate the abusive and oppressive system that reigned.
As soon as the murders ended, "Red" disappeared.
Nobody knows what happened to him, where he is, or if he's still lives.
Truth is that some might look for him for revenge.
But there's other side to the story, a side in which some people claim that he was more than just an assassin, they say he was a LEGEND.
