As the assassin lord of the 23rd century fell into his death, his guardian had used his influence in the 18 Rings of Hell to sway the Yama's judgment on his charge.
This Assassin lord had used his skills and power to punish wrongdoers, and expose the truth of criminals and politicians. However, his path of protection and truthfulness lead him to an early grave, killed by his enemies and his family he walked to meet his judge, Yama.
After his verdict was decided Yama sent him to the wheel. This human would be reborn into the Asura realms human world this world would be judged by a different deity so any bearing he had on Earth would be irrelevant and the laws of existence would be different than Earth.
