Dancing Ghost was born into a royal family of the Red Valley, home planet of the intergalactic exorcists. As an only child of the queen and the sole heiress to the throne, Ghost was raised in a heavily guarded castle, away from all the dangers of the world. All the power and wealth loomed large within her reach. However, she began to have qualms about her birthright, questioning the justification for her privileges. When she finally finished her training and became a denominated exorcist, she ventured outside to prove herself as the rightful queen.
