The story of RG Veda took place in Tenkai, the heavenly world that used to be very peaceful under the rule of Tentei the Emperor. One day, Taishaku-ten, one of Tentei's warriors, rebelled against the Emperor. He defeated the strongest warrior in Tenkai, Ashura-Ou, who was also the Guardian God of War, and killed the Tentei to take over Tenkai. Taishaku-ten then crowned himself as the new Tentei. This was referred to as the Holy War. 300 years after the Holy War, a prophecy by a stargazer named Kuyou foretold the future of Tenkai. It was said that the gathering of six particular persons, known as the Six Stars, would result in the "break" of the Heavenly World. The story then begins.

Thus the wheel of destiny begins to turn towards the "Break" of Heaven...
