Narrator: Yin and Yang, Light and Dark, Good and Evil. The universe was comprised of two opposites, Positive Ki and Negative Ki, two forces in a silent eternal battle against each other that keeps the universe balanced. However, when the Zoto crystal was formed, all Negative energy was stripped away, resulting in an abundance of Positive Ki, which now without it's counterpart, threatens to tear the universe apart. Shinigami, emanator of Dark Ki, has returned to our Universe, now physically manifesting himself to do battle with his immortal rival. Whoever wins, the universe will lose.
