Corona is a knight, the daughter of the two best knights in the entire kingdom. She has lived her life training to become as great as they are, but she has something that gives her an advantage over almost all other Knights, including her parents. Psychic powers that she must keep hidden, for her parents see them as nothing more than lazy ways of fighting with an unfair advantage.

There, she is charged with defending Princess Anne, and they quickly become amazing friends. One day, they wake up to find the castle under siege and the Queen disappears. The two are discovered by a handsome knight, and he takes them back to his kingdom where they can wait for the Queen to return. Soon, however, Corona finds out a dark secret of the knight. Before she knows it, she and Anne are drifting apart, and Corona remembers her duty to protect her, but how can she protect the Princess from a man that has stolen Anne's heart?
