The ancient agreement of mutual non-intervention between humans and demons has begun to fall apart as mankind derails to the dark path. Humans and demons have colluded in criminal gangs and corporations, causing havoc and bringing forth an age of chaos. But those who follow the path of virtue have not been left powerless.
