As heir to the throne and royal priestess of the Elleraldian faith, Cecily is a well-loved and well-endowed figurehead of her kingdom. Though she cares deeply for her people and wishes to help them in any way she can, she secretly resents her own weakness and envies the brave warrior Noein.

Seizing the chance to gain power and defend her subjects, she becomes Eden’s Ritter Lucifel, a powerful magic-wielding warrior. But due to the forbidden nature of her new abilities, she must keep her identity a secret from the people she has sworn to protect.

The leader of the Holy Guard, Noein is a hardened war veteran, adored by people far and wide. Not only has she devoted her blade to Princess Cecily, but the two have been close friends since childhood; to this day, to this knight, no sacrifice is too great to protect her princess.

As the bulwark and buttress of the capital’s defenses, her reluctant absence has left a gaping hole. How long can the city stand until she makes her return? And will her sword alone suffice for her to safeguard what she loves?
