What is aurora fairy?

As an AI language model, I do not have any information on an "Aurora Fairy" as it is a fictional character. However, Aurora refers to the natural phenomenon caused by charged particles colliding with atoms in the Earth's atmosphere, creating a colorful display of lights in the sky. Meanwhile, fairies are mythical beings commonly depicted as small, magical creatures that possess supernatural powers and abilities. It is possible that "Aurora Fairy" refers to a fictional character that embodies the beauty and magical qualities of the aurora borealis.
