Un Kajou, also known as Yun Huaniang, holds the position of Duck Consort in the imperial court. Granddaughter of Prime Minister Un Eitoku, she shares a childhood history as playmates with Emperor Ka Koushun, exhibiting more tomboyish traits in her youth. She is three years Koushun's senior and approximately ten years older than the Raven Consort, Ryuu Jusetsu; her youngest sister is Jusetsu's age. As Duck Consort, she possesses the second-highest rank among the imperial consorts. Residing in Enou Palace and with no empress appointed, she manages the inner palace affairs. Her position requires her to maneuver through complex court politics, including addressing rumors and jealousy arising from Koushun's frequent visits to the Raven Consort. She initiates contact by visiting Ryuu Jusetsu at Yamei Palace, seeking clarity on Koushun's activities and inquiring if he requested a deadly curse against the Empress Dowager. This encounter reveals both diplomatic caution and underlying concern; she expresses relief after meeting Jusetsu and indicates a desire for future communication. Their interactions evolve, particularly after Jusetsu assists her in resolving a personal matter involving a former lover, leading Un Kajou to regard Jusetsu with sisterly affection. Her characterization emphasizes pragmatism and strategic awareness. She operates with measured confidence in her duties, reflecting her understanding of palace dynamics and her role within them.
