Shoukun Hyou was the mother of Shuurei, adoptive mother of Seiran, and wife of Shouka. She was known as a legendary beauty with a kind heart to match. She taught Shuurei how to make steamed buns, discovering Shuurei was a much better cook than she was; how to pick tangerines from the trees, and how to behave like a lady. She also gave the name 'Seiran' to the boy she and Shouka found lying in the snow when the family traveled to Kiyou. The name meant 'Silent Orchid', and was given because the boy that they found never said a word and was presumed to be a mute. She grew very close to both Shuurei and Seiran, and encouraged Seiran to smile all the time to make Shuurei happy.
Shokun is later revealed as the Rose Princess (Bara-Hime) of the Hyou family. She had the ability to cure any illness and many men sought her hand in marriage. Her beauty even mesmerized the leader of the Hyou family, Riou, who locked her from the world. She was considered a threat by the previous Emperor and was targeted for assassination by a woman called the Black Wolf, who failed and died in the attempt. The Emperor appointed a new Black Wolf, nicknamed Kaito: Shoka Hong. However, Shoka fell madly in love with the Rose Princess during his first meeting with her, causing him to abandon his mission and carry her away. After some time and difficulty, she returned his feelings. Afterward, she lost her powers of healing but retained the power to make one wish come true, which she used to make Shuurei healthier at the cost of her own life. Shokun is eventually revealed to be the Red Immortal, one of the Eight Sages who served the first emperor; her spell to make Shuurei healthier is the result of sealing her spirit within her daughter. Though her spirit is dormant within Shuurei's body, it is said that Shūrei will lose her own personality and "die" when the Red Immortal's spirit inevitably awakens.
