Asura

Asura is a beautiful looking woman. The people of that land call her and her kind, demons. She is extremely powerful, possessing incredible magical powers, whose destructive properties rivals a god. She is first introduced as a mysterious character who plays a subtle hand in aiding Kurohime and Zero defeat a witch. She is next seen fighting a Mountain God and is severely wounded while protecting Zero and Kurohime. Shortly after being tended to by Zero, they are attacked again by the Mountain God, and Kurohime and Asura team up together to destroy their enemy.

She is attuned to the element of fire, and much of her magic revolves around flames. She also has a demonic form that allows her to use her powers more efficiently. However, as a demon of fire, she is vulnerable to water and cannot swim. She was initially reluctant in having anything to do with Zero and Kurohime, but after being saved by Zero and witnessing the power of a vengeful Kurohime, she has a change of heart, and tells Kurohime about her master who seems intent on helping Kurohime regain her full power.
