A daughter of the Shu family, who govern the element of Fire. Backed by the Noble Consort Shu Gabee, she resides in the Maiden's Palace as a consort candidate for Crown Prince Ei Gyoumei. However, due to her lower-class birth within the clan and her own poor reputation, she is despised by those around her as the 'talentless gutter rat' and is treated with contempt by everyone in the palace. Since the incident, she seems to have become close with Kou Reirin of the Kou family?

The Crown Prince of the Ei Empire and the next Emperor. He is addressed as 'Your Highness' and served with utmost devotion by many. Shin-u, the Captain of the Vulture Guards who oversees the inner court and Maiden's Palace, is actually his younger half-brother (though this is kept secret due to the complexity of Shin-u's birth). He dotes on his maternal cousin, Kou Reirin, to such an extent that others call her 'His Highness's Butterfly,' but his obsession often makes him lose sight of his surroundings. He is a handsome young man, accomplished in both literary and military arts, sincere, and highly responsible. He possesses 'Ryuki' (Dragon Qi), which causes his emotions and physical condition to instinctively influence the weather and environment.

One of the Vulture Guards, officials (a type of military officer) who maintain discipline in the inner court. He holds the position of Captain of the Vulture Guards. He is actually the younger half-brother of Crown Prince Ei Gyoumei (meaning his father is the current Emperor, Ei Gen-you). He has blue eyes inherited from his mother, who was a foreign slave. Due to these complex origins, he has not been welcomed into the Imperial Family despite being the Emperor's son. He strongly inherits the psychological traits of the Gen family from his father's side, rarely letting others read his emotions through micro-expressions. His reactions to sudden emotions like laughter or anger are often delayed by several beats. Because he approaches people (especially Reirin and Keigetsu, for better or worse) without revealing his feelings, he can frankly be quite intimidating at times.

A lady-in-waiting to the Maiden of the Shu family. Her rank is 'Araishu' (flesh-pink), which corresponds to a lower-class attendant. A mixed-race girl with red hair inherited from her mother, who was a dancer from the western country of Shelba. True to the Shu family bloodline, she is emotional and impulsive. Having grown up in the downtown slums, she reverts to a blunt and rough way of speaking even toward superiors when she lets her guard down. She is somehow managing to get by with Lady Keigetsu.
