Imo Kusa Reijou desu ga Akuyaku Reisoku wo Tasuketara Kiniiraremashita

Because of her family's obsession with tradition, Agnes, who always wears old-fashioned dresses and makeup, is ridiculed in high society as an outdated "country bumpkin." As a result, she often attends parties hoping to find a fiancé, only to suffer defeat after defeat...

While attending another party today, Agnes accidentally saves Nazelbert, the son of a duke whose engagement was broken off by the princess. Then, upon seeing this, the princess orders her to marry him and be exiled to the frontier! Any ordinary young lady would be devastated, but Agnes, who had found her family's policies annoying, readily agrees, knowing that she can enjoy a carefree life on the frontier!

With the help of a skilled maid, she is able to shed her country bumpkin look, and using the powers of her newly developed strengthening magic, she fights hard for the frontier! As a result, the people of the frontier, who were initially cold towards her, gradually begin to accept her! What's more, Nazelbert, who she ends up marrying, is gradually growing closer to Agnes...!?
