The anime is based on Almond’s light novel series of the same name which is illustrated by Yoshiro Ambe. A manga adaptation by Yona Etō is also being published. J-Novel Club publishes both the light novel and the manga in English and describes the story as:
Lady Carolina, the overlooked daughter of a powerful duke, has always believed herself to be the black sheep amid her illustrious kin. Her father is the distinguished prime minister; her elder sister, a prodigious mage destined to become their nation’s next Saint. In comparison, Carolina resigns herself to a quiet existence in their shadows until a sudden and unexpected royal decree alters her destiny, thrusting her into a political marriage with the formidable “Bloodthirsty Prince” of the neighboring Empire of Malcosias. Determined to prove her worth, Carolina takes a bold step into a world fraught with both political and mortal peril. As royal obligations intertwine with hints of true love and the stirrings of her own latent power, Carolina moves ever closer to understanding what it truly means to be exceptional.
