Hao Asakura

Hao grew misanthropic over time, as his Reishi abilities became too strong and eventually went beyond his control. As the negative emotions and thoughts of others were constantly overwhelming him and, since he was unable to turn his Reishi off, the deluge of negativity eventually created an "Oni" inside his own heart. The internal confusion and disorder that was created eventually led to his desire of creating the Shaman Kingdom on Earth and drove him to become the Shaman King in order to reach this main goal. Nonetheless it was the unjust death of his mother that caused the initial spark of his hatred for humanity. In his third and most current incarnation, Hao is usually calm, cruel, and always had a smile on his face. The occasions when he is really upset which is rare and when he is upset with else, that person is usually killed off and burned to death down to their soul by The Spirit of Fire. It is revealed that despite his cruelty and his destructive acts, he is in fact a deeply vulnerable person unable to move onwards due to his obsessions.
