In Saiunkoku, a fictional medieval empire, we follow the journey of Shuurei Kou, whose family has fallen on hard times. Her father works as a librarian in the Imperial palace but earns little compensation. Meanwhile, Shuurei teaches at a temple school and does odd jobs to make ends meet while pursuing her dream of passing imperial examinations and taking up government positions, which are forbidden to women. However, her plans take an unexpected turn when the Emperor's Grand Advisor offers her a six-month position as his consort in the imperial household. If she succeeds, she will receive significant financial rewards. The story explores Shuurei's relationships with the Emperor and other court members, the intrigues of imperial politics, and her determination to improve herself and her country.
