Since 500 years ago, Victoria heads into greater despair due to the influx of demon-possessed souls known as "The Fallen". The ones who govern Victoria have gathered a group of Knights known as the Mystic Dogs who presumably have the blessings of the Goddess, "El" to combat the Fallen and hopefully end the Demon Realm's reign of terror. The story follows a young woman named Revery who has a strong desire to become a knight. What she is ultimately fighting for, only time will tell.
