Chouka

Originally from a foreign country but stowaway to the Ken Empire. She was then picked up by Keirou and now serves him loyally. Now a court lady attached to the Emperor where she guides the weak-willed Emperor to follow Keirou's wishes. She distrusts Ryuukou and Shoukaku, despite them claims to serve Keirou. In the anime, Shoukaku deducts, apparently correctly, that she is in love with Keirou.
