Jokaku was Youko Nakajima's immediate predescessor as the ruler of Kei. After her death, she was posthumously known as You-ou, the Prophet-King. Jokaku's inability to control of the court resulted in her withdrawal into the Inner Palace and refused to involve herself in governing Kei. She became susceptible to flattery and elaborate gifts from her advisors - including a small village of elderly people and children that she would frequent in order to teach children embroidery and poetry, reflecting the ideal life she wanted; this gift was from Gahou, who Jokaku rewarded by making him the governor of Wa. Her sister, Joei, encouraged Jokaku's withdrawn behavior and used Jokaku's affection for her in order to gain power in court. In hopes of improving Keiki's relationship with Jokaku, the Genkun Gyokuyo on Mount Hou, arranged for Keiki to help Taiki and learn to be more sensitive to the feelings of others. However, Keiki's awkward kindness caused Jokaku to fall in love with him. Out of jealousy, she banned all the women from the palace and then the entire country, so that no else could take advantage of Keiki's kindness. Jokaku's tyranny continued until Keiki fell ill with shitsudou. Grief-striken, Jokaku realized that she had lost the way and ascended Mount Hou to abdicate her throne and end her life in order to save Keiki. (Source: wikia)

Rangyoku is a resilient and cheerful sixteen year old girl who lives in a rike in the Ei Province. She and her younger brother, Keikei, originally came from the Wa Province. When their parents died late during the reign of Jokaku, they elected to leave Kei, but they changed their minds when a new ruler supposedly ascended. Despite the fact the ruler, Joei, turned out to be a false queen, Rangyoku and Keikei remained in Kei and were able to enjoy the ascension of the true monarch, Sekishi. In the rike, Rangyoku helped take care of household tasks for one of the village elders, Enho. When their rike is attacked by youma, a number of people are killed until the arrival of Chuu Youshi, a young woman who is staying with Enho as a guest. Rangyoku quickly becomes friends with Youshi and helps teach her about every day life in the Twelve Kingdoms. However, when Youshi is away, men ordered by Gahou, the governor of Wa, arrive to kill Enho. Keikei is badly injured and Enho is abducted. Rangyoku is fatally wounded and stumbles into Youshi's room, where she finds the seal of the king of Kei. Realizing that Youshi is the new monarch of Kei, Rangyoku spends her last moments concealing the seal so the attackers will not learn that the ruler of Kei has been residing with Enho and prays for Youshi to save Keikei.
