The world is full of mysteries and secrets.
In the shadows, beyond what ordinary people can see, demons, witches and other supernatural beings live and fight.
But on a night 20 years ago, the balance of this world was offset. Until today, no one knew what truly happened that night. The only sign, one that even normal humans could sense, was the 'Hoshi no Ame': a rain of colorful stars all around the world. Since then, there have been several mysterious occurrences that even supernatural beings could not explain.
One of these occurrences is the appearance of the Shin.
The Shin is a mysterious special ability granted to a few human children who were born in the past 20 years. However, this power comes at the cost of great misfortune, bringing danger to to the bearer and those around them. Because of this several tragedies happened.
Now those children, who have survived such a cruel fate, are slowly gathering in one place to finally reveal the truth:
Aurora Academy.
