The story follows Ani, a princess of the small but peaceful nation of Inaco. She is sent to the signing ceremony of a peace treaty between the powerful military nation of Militonia and the religious nation of Selenfallen. However, the ceremony is thrown into chaos by the presence of several eccentric and problematic princes who are anything but ideal royalty. Ani finds herself tasked with the difficult mission of keeping these 'dame' (no-good) princes in check while navigating the complex political tensions between their respective kingdoms. As the series progresses, Ani must deal with the narcissistic Prince Narek, the lazy Prince Ruze, the charming but manipulative Prince Mare, and the mysterious knight Teo. Through a series of comedic mishaps and character-driven developments, the group forms an unlikely bond. The anime explores themes of personal growth and responsibility as the princes slowly learn to overcome their flaws and step up to their duties, all while Ani tries to maintain the fragile peace of her homeland.
