Your house wasn't necessarily big enough to hold all nine demons, but somehow they managed to expand it through their powers. You now have to live with those chaotic demons, their initial goal was to conquer Earth, but they slowly accept the way humans live and start to become familiar with you... in more ways than simple friends.
