Shashi  

In the beginning, Shashi was just a miko for Ashura-ou along with her sister Kara. However, being a simple miko wasn't enough for her. Later, she married Ashura-ou and became his wife. But even then, it wasn't enough for her, so during the Holy War, she helped Taishaku-ten in his rebellion by revealing all the secrets of the Ashura clan to him. Her betrayal led to the complete destruction of Ashura-ou and his clan. As a result, she became Taishaku-ten's wife, "Empress" Shashi. She gave birth to twins, one being Taishaku-ten's son and the other being a child from the Ashura clan (Ashura-ou's child). Despite her attempt to kill her own child Ashura with her own hands, she was unsuccessful.
