Gyokuyo

玉葉

Gyokuyo serves as Youko's personal handmaiden during her reign as the monarch of Kei. She holds a high rank among the palace staff and is entrusted with overseeing Youko's well-being in domestic matters, having served the kingdom for a long time. Although she appears to be a woman of middle age, Gyokuyo's actual age is unknown, and it is implied that she is much older than she seems.
Before becoming Youko's personal maid, Gyokuyo worked in the Ministry of Spring, where she was involved in administering the kingdom's education system. However, she was removed from her position late in Jokaku's reign when the late ruler banished all women from Kei. Although Youko remarks that she thinks it would be good for Gyokuyo to re-enter the administration, Gyokuyo tells her that she is satisfied with serving as Youko's maid.
