The mysterious blade Sento was wielded by the Warrior Kings for many generations, until it was no longer used and was placed on the Well of Souls in the tomb of the Kings inside the House of Pekara. It was remained unused and undisturbed.
Centuries later, a young and proud fighter, Kenshi who lived by the sword, was approached by an old man called Song who offered him a powerful weapon, a sword that will make him the greatest warrior that ever lived. Kenshi agreed to this. He went with Song to an ancient temple and enters alone. He passed through the underground labyrinth that was under the temple, and found himself in the catacombs. There he saw a sword on a stone well-like monument, Kenshi then pulled the sword out of the stone and spirits suddenly bursts out of the monument and were unleashed, fever blinding Kenshi. They were then asborbed by Song who revealed himself to be none other then the vile sorcerer Shang Tsung. Kenshi was left there to die in the tomb, but the sword Sento came to him and revealed that he was a direct descendant of the legendary Warrior Kings. It then let him out of the depths and saved him.
With the aid of his ancestoral sword Sento, Kenshi vowed to destroy Shang Tsung and free his ancestors from their captor.
