The Living Nightmare
A boy labelled CR-155 or Criss as he refers to himself, is a boy who has lived a very sheltered life spending all of his time a school with the only thing he would learn was the almighty power of lord and that "Hard work is the skeleton key to all locked doors towards the path to happiness." So he continues to work hard so that he may be granted the right to serve the lord in the real world. Until he makes a fatal mistake causing The Living Nightmare to be awakened and ruins any possibility of that becoming a reality. Wanting to fix his mistake for its awakening he takes it upon himself to hunt the creature down which allows him to learn more about outside world, the beings that haunt it and to realize that hard work might not be a true skeleton key.
