After accompanying her fiancé, Prince Henri, on a quest to defeat the Demon King, Romelia von Graham finds herself unexpectedly cast aside. Deemed useless for her lack of combat abilities, she is stripped of her engagement and sent home in disgrace. Returning to a homeland devastated by years of war, Romelia realizes that defeating the Demon King has not brought true peace. Demonic forces still threaten the kingdom, the economy is in ruins, and countless people struggle to survive.

Using her remarkable talents in strategy, negotiation, finance, and intelligence gathering, she sets out to rebuild her province, establish an army, and restore stability to the kingdom. As new enemies emerge and political conspiracies unfold, Romelia must prove that true leadership requires more than strength alone.
