The historical fantasy romance novel series is written by Akumi Agitogi and illustrated by Tsukiho Tsukioka. It was first published under Kadokawa’s Fujimi L Bunko imprint on January 15, 2019 and has released 10 volumes in Japan as of March 2026.
The light novels have also inspired a manga adaptation from Square Enix drawn by Rito Kosaka and is published in English by Square Enix Manga & Books. A live-action film was also released in Japan in March 2023.
Yen Press licensed the light novels for English release and describes its synopsis as:
Born talentless to a noble family famous for their supernatural abilities, Miyo Saimori is forced into an existence of servitude by her abusive stepmother. When Miyo finally comes of marriageable age, though, her hopes of being whisked away to a better life crumble after she discovers her fiancé’s identity: Kiyoka Kudou, a commander apparently so cold and cruel that his previous would-be brides all fled within three days of their engagements. With no home to return to, Miyo resigns herself to her fate—and soon finds that her pale and beautiful husband-to-be is anything but the monster she expected. As they slowly open their hearts to each other, both realize the other may be their chance at finding true love and happiness.
