An old man who trained Hakufu when she was a child. He is an old friend of Goei, and he possibly trained her too, and has also trained Ukitsu and Rikuson. He explains to Goei about Hakufu's fate to be killed by Ukitsu. When Ukitsu was recovering from her fight with Hakufu, Chokou mentions that her loss to Hakufu was a necessary sacrifice needed to awaken Hakufu's dragon. He is currently trying to teach the Water Dragon Fist to Hakufu with the help of Rikuson and Saji.  In the anime, he is referred by Hakufu as "Grandfather" (it may just be a title, as elderly family friends are called grandfathers in Japan), and he helps train Hakufu and Ryomou at his hot springs. He is also shown to be slightly perverse, as seen during one sparring session when he purposely knocked both Hakufu and Ryomou into a lake just to see them wet. In Dragon Destiny, he is the one who performs a revival on Hakufu's body where he only manages to awaken her dragon, but was able to keep her dragon under control. He tells Ukitsu that only she is able to revive Hakufu's spirit. We find out that he also trained Hakugen. At the end of the series, he and Hakugen are seen attending Ukitsu's grave, and he gives thanks to Ukitsu for sacrificing her life in order to save Hakufu, thus changing the fates of many fighters for the better. 

Seven schools are constantly 'at war' with each other, and the students within - both male and female - have become skilled fighters and constantly battle with rival schools. Their lives and fates are guided by strange jewels that contain the spirits and destinies of warriors from the Sangokushi period. One girl, Sonsaku Hakufu, has recently moved to Japan and is apparently destined to unite the schools as her counterpart united seven countries long ago. But, like all heroes, there is a darker side to her fate, and as always there is a constant struggle by those around her to break the chains of their own destinies and make their own lives.<br><br>

Sealed in ancient jewels are the spirits of the heroes who tried and failed to unite China in the Three Kingdoms era. These jewels have been scattered throughout Japan, and have the power to draw out the full potential of those who inherit them. However, those owners, known as Toushi, are possessed with an insatiable appetite for battle. Hakufu Sonsaku is one such Toushi. Living in the country, Hakufu's desire to beat something to a pulp goes unfulfilled until her mother tells her to go to Tokyo, where she starts training with other Toushi and sets foot on the path to her destiny. <br><br>
