The princess of Augland has turned 21. As successor to the kingdom, she must marry.
She understands the feelings of her elder brother who arranges many suits, but each suitor rejects her.
The reason------she is called a witch.

Her mother was a prostitute.
She bears this eternal stigma, spoken of as a devourer of men only fit to attract the lowest of lows.
This, anyway, is the circumstance of her thoughts. Feeling despised and believing the world's judgment,
the pure-hearted girl has still never been kissed.

Nevertheless, prince Walt tirelessly searches for a noble, marriagable aristocrat.
At last he finds Eya, who is different from the others. Eya agrees to marry the princess.
There was no reason for celebration, for the princess. It seemed too strange a match.
There must be something... wrong... beneath his visage.
No matter how she racked her brains the princess can't identify the problem.
She only feels an eerie dread around his knight.

What mysterious secret is Eya hiding?
What hostile truth lurks behind the clouds of what should be a joyous union?
