Creation
The Hito-Shura (人修羅) or Demi-Fiend, is the protagonist of Shin Megami Tensei III: Nocturne. He was originally a high school student, who had gone to the hospital to visit one of his teachers, Yuko Takao. In reality, she had led him there so that he could survive The Conception. Following the Conception, Lucifer infects the student will a demonic parasite called Magatama. This transformed his body into a demon like body with glowing tattoos and a horn growing from the back of his skull. This allows him to fight like a demon, as well as communicate with them and summon them.

Importance to Shin Megami Tensei III
The Hito-Shura is an important component to the Conception. The Miroku Scripture had predicted that the Hito-Shura would be created and would be able to alter the results of re-creation. All the remaining humans in The Vortex World desire for Hito-Shura to side with and support their Reason. Using his strength, Hito-Shura opens a path to Kagutsuchi and defeats him. The path the player takes to get there determines what the result of Conception will be: the creation of a new world, restoration of the old world, or the shattering of the cycle of creation.
