Long ago, there once was a kingdom called Goyou where youkai were forced into servitude using the mother and child talisman. One day, a youkai rebellion occured in that kingdom. Youkai who had spent hundreds of years being oppressed rose up seeking their freedom. That was also the day of the Goyou kingdom's princess's wedding. As the youkai lay siege to the castle a single man faces them in an effort to repel their attack and save the woman he loves. This is the story of the Northern Mountain Emperor.
