Thirteen for thirty years while her father was King of Hou, her name was Sonshou but she was called Shoukei. She lived like a spoiled brat in the palace because her father would never let her out into the kingdom. When her father was overthrown by Gekkei, her mother and Hourin (kirin) were killed before her eyes. She was then removed from the registry of immortals and forced to live out her life in a rike in Gekkei's Kei province. Three years later, she looked nothing like the over-dressed princess and felt even more bitter. She blamed everyone else for her misfortune and never once tried to understand anyone else's perspective. She considered Gekkei a usurper who wanted nothing but the throne and was unjust in his taking it. She couldn't understand why anyone would praise him for his actions, especially since she believed he was living lavishly in a palace while she was forced to suffer. When her identity was revealed to those living in the rike, they attempted to kill her. Only the old matron had enough self-restraint to run to Gekkei's palace and have someone sent to remove Shoukei in order to save her life. Gekkei then exiled Shoukei to the kingdom of Kyou where she was allowed to stay in the royal palace on the condition that she work as a servant. She would not be made into a Sen-nin, though, because the queen thought she had too much pride. Shoukei agreed to stay but she hated it. Working as a servant meant she had to bow. So she stole treasures and escaped to Ryuu. She heard there that a person could get land and citizenship without a pass if they came from Tai. Thinking this would be a great way for her to get close to Youko, she decided she'd go to Tai and then to Kei. Before this plan could come to fruition, she was arrested and spent a night in jail with Rakushun. He slowly came to gain her trust and show how spoiled and self-indulgent she had been throughout her life. By the time Shoukei reached Kei, she was a better person. She wanted to get to Youko not to hurt her, but to tell her what would happen if she lost her way. She unknowingly met Youko in the Wa Province when she threw a rock at a soldier during a public execution. From there she met up with the rebel group who want to overthrow Gahou, the evil lord of the province. While on assignment to pick up touki weapons, she stayed with Suzu. The two of them share information about the rebellions. Shoukei assured Suzu that Youko was a good person and would have done all she could to help Seishuu. Now completely reformed, Shoukei had learned to empathize with other people. She was appointed courtier by Youko. She sent a letter to Gekkei apologizing for her behavior and hoping that he would take the throne until the new ruler was chosen. (Source: A Twelve Kingodms Fansite)
A little girl who makes and sells candies. Youko denies an offer to eat lunch with the girl and her family. In the novels, she and her mother make a very brief appearance in The Twelve Kingdoms: Sea of Shadow, where she is referred to as Kuyo. She and her mother find Youko on the road in a forest in Kou. Noticing that Youko is exhausted and near collaspe, Kuyo offers sugar water to Youko to help rehydrate her. However, Youko rebuffs the efforts of the mother and daughter for her to travel with them into a town for the night, as Youko is unable to trust others after being betrayed so many times. When Youko meets them again enroute to En, Kuyo inquires after Youko's health, noting that her mother had told her that Youko had been grumpy because she had been tired. Youko thanks Kuyo and her mother for their kindness before parting ways with them, as she tries to find Rakushun. In the anime, Gyokuyo's role is expanded alongside her mother's role. She travels with her mother and a group of performers. Like her mother, she is a shusei. (Source: 12kingdoms wikia)

Shoushun is a nyosen (female sage) who resides at Mt. Hou. She is among the fifty oracles dedicated to caring and protecting the young kirin (a creature that chooses the ruler of each kingdom) that are born on the mountain. Shoushun was from village in En that was suffering from Setsuzan (the destruction and devastation of one's kingdom caused by a corrupt king) caused by the previous king, Kyou-Ou, repressing his people. One day, her village had burned down to the ground and only the village children survived the fire. She came upon the shrine of Oubo and prayed to Seioubo of Gozan to be taken to Mt. Hou and become a sennin. Shoushun held onto a fallen pillar and kept chanting to Seioubo until she was visited by the people of Gozan and became a sennin. When Shoushun meets Enki, she becomes his frequent companion and tells him of his duty to eventually choose the next king of En, whose presence should stabilize the state of En and bring peace again. However, she is deeply saddened by Enki's cynicism and determination never to choose a king, believing them to be war-mongers who do nothing but destroy lives and entire nations.

When Suzu flees from the Bluemist Aerie and the service of the flying sage, Riyo, Kouko and Sairin give Suzu sanctuary in the royal Choukan Palace. While Kouko promises that Suzu will not be removed from the Divine Registry, she does not allow Suzu to join the servants taken from Riyou's aerie to work in Choukan Palace. Because believes that Suzu must learn to understand how others are feeling rather making assumptions and becoming disappointed when the person does not live up to her expectations, Kouko sends Suzu away to try and see more of the world. While she is somewhat disappointed that Suzu insists on going to Kei believing that the ruler of Kei will understand her better than Kouko or Sairin, Kouko provides Suzu with a travel pass and funds, in hopes that Suzu will learn from her experiences.
