Defending Chicago from dark forces is a grueling job, especially when you're just a senior student classes.

But when they infiltrate the school, Lily remembers who and what she swore to protect. She dives into searching for her magical powers and suddenly discovers that they have disappeared. It turns out that she is not the only one who has encountered this problem. A magical blackout, the origin of which no one knows, blocked the path to all paranormal forces in Chicago.
