Yasha-ou is the King of the Yasha clan and Bushinshou (warrior god) of the North, also happens to be the strongest one out of the four bushinshous. His given name is Yama, that is what it was before he became Yasha-ou. After he heard the Prophecy from Kuyou, he became very interested in the whole rebellion deal, so he went and broke Ashura's seal and freed him. After the Yasha clan was demolished because Ashura was brought into the village, Yasha-ou and Ashura set out on their journey to find the other members of the Six Stars. Yasha-ou is a pretty stoic person who doesn't like to talk much, but is very determined to defeat Taishaku-ten. Yasha-ou is Ashura's best friend and a kind of fatherly figure for him.
