There was a world that existed in a galaxy that thrived and coexisted with magic. It was called Xia. It was lush with plants and filled with animals. A large number of majestic and mystical creatures roamed in this blissful utopia. Among the most treasured were the unicorns, they were guardians of every living thing. Everything was peaceful and just, and evil was not known there, until an evil force entered the galaxy and destroyed everything in its path. The world itself also became a victim to this force; therefore, the once peaceful and beautiful planet turned into a dangerous and barren wasteland. The wise and kind wizard, Yinglong, who helped protect the land, managed to preserve a little bit of the world's beauty and saved most of the creatures. Unfortunately, he was not able to protect the unicorns, but the unicorns' fate was not all lost.

The rulers of the unicorns managed to save their only daughter's soul. Her name was Annchi. When the king and queen learned of their beloved daughter's death, they decided to use the legendary Crystal of Life in order to preserve Annchi's soul. However, in doing so their lives would be lost forever. Ignoring the risk, they used all their power to make sure that Annchi's soul was sent to the future where she would be reborn. They succeeded at the price of their own lives. But something else happened. During the process, Annchi's soul separated into two parts. One was her unicorn soul, and the other was her human soul. When both of Annchi's souls were reborn, it had been ten years since what came to be known as the Invasion. The human Annchi, having no memory of her identity or her past life, was born to a poor yet loving family. Evil had spread throughout the galaxy like a disease, but there was still good in different places.

And so this story began in the year 1100, eighteen years after Annchi's reincarnation. Unlike her days as a unicorn when she was a care-free, spirited, and graceful young woman, Annchi was now melancholy, quiet, and withdrawn. She knew that she was different and felt that something was missing from her life.

Annchi only had one friend, a little girl named Lanying. The eight year-old was the complete opposite of Annchi. Where Annchi was shy, Lanying was outgoing. Annchi's figure was willowy and seemed fragile. Lanying's figure was slender and athletic. Annchi trusted her instincts whereas Lanying trusted her mind. Annchi was pale completed and her platinum blonde hair was nearly white. The only color on her face was her piercing, celestial blue eyes. Lanying held more color to her face with her peachy skin and pink cheeks. Her hair was dirty blonde and her eyes were hazel. Despite their differences, they both went together like two peas in a pod. They also knew of the evils around them, but never imagined how drastically it would turn their lives up-side down.
