To everyone: This story originally belonged to Vengeful Spirit. He openly offered this story out, and I have taken it over. It shall be going through edits and changes, until hopefully, it can be completed and put out for everyone's enjoyment. As it stands now, it still contains the original chapters Vengeful published, so it is unedited.
