Mujikaku Seijo wa Kyou mo Muishiki ni Chikara wo Tare Nagasu

Carolina has always considered herself the least remarkable member of her family. Her father is a powerful prime minister, her elder sister is a gifted mage expected to become the next Saint, and Carolina has resigned herself to living quietly in their shadow. Everything changes when a royal decree sends her into a political marriage with the feared Bloodthirsty Prince of the neighboring Malcosias Empire.

Determined not to become a burden in a foreign court, Carolina begins helping people in ways she considers ordinary. She does not realize that the power flowing from her without conscious effort is anything but ordinary. As royal politics, danger, and genuine affection enter a marriage arranged by others, she approaches a truth even she has overlooked: the real Saint may have been standing in plain sight all along.
