Shusui Hyou is Shuurei's main lady-in-waiting during her time as an imperial concubine. Her beauty is said by Ryūki to be comparable only to Kochou, the famous courtesan in the Red Light District. She loves the smell of sandalwood and had kept a fan made of sandalwood as a prized possession, though the fan is later given to Shuuei. Shusui is deeply attached to Shouka, although he doesn't return her feelings, and is the only person who says that his tea is delicious. She is terrible at embroidery, which Ryuuki likes to tease her about; when she attempts to make a sunflower-like floral pattern, Shōka mistakes it for a lion. Shusui appears kind and caring to Shuurei and Ryuuki, although Ryuuren is suspicious of her swift agility in dealing with Kourin's clumsiness.
