Shura

About
The main character of AmbivalenZ who is also known as the cursed knight. Before being cursed he served the kingdom of Saeruuna as the 5th strongest of 17 knights. His job was to protect the princess since her birth.

This ultimately went wrong and Deirdre came to be who summoned a dragon who was cursed with immortality, upon slaying it he got covered in its blood and suffered the same curse. He turned Albino in the process and now only lives for revenge.

After roaming the world, slaying Duendy and thwarting their plans, he ultimately settles for a time in the town atop the Lid of the Kettle of Hell where he meets the then 15 year old Ky of the time, Shou Ky. They travel together to do more of the same and at the start of the game he is still doing just that, but Shou Ky only seals them now.

He is an accomplished swordfighter who uses the negative Kusanagi and air magic to fight. He has also gotten quite knowledgeable when it comes to Duendy and uses this knowledge to combat them. His years of living through horrible events leave him cold and uncaring.

Trivia

 * The name Shura has ties to Buddhism in Japan, namely the term Asura which refers to a demigod.
 * This fits in well with AmbivalenZ as the Asura are a case of dualism, with the Deva and Asura being two sides of the same coin.
 * As they are always in conflict with the other side, it depicts Shura and the Duendy quite well.
 * In his own tongue his name is written as シュラ.
 * He isn't totally immortal as he can still die if he gets beheaded.
 * He also heals 5 times as fast thanks to the curse.
 * Makes a cameo in Toushin Toshi 2 as one of the dimensional door opponents.
