As the inhabitants of Aries go stronger in the ascension system, they go from the first step all the way to the fourth step. The fourth step is equal to the C grade, and only the Sovereign of the world can possess such a power.
The Sovereign of Aries can reach the power of 99C or 1B. A little more power will bring the power of the Sovereign to 100C, which is 100%B or simply 1 B.
With this kind of power, the Sovereign of the world should be unmatched in the whole world. After all, not only is the Sovereign the only one at the fourth step, but she is also reaching the limit of the fourth step.
So, usually, Sovereigns die of old age. But the previous Sovereign, Taka's mother, was killed.
There shouldn't have been anyone who could threaten Taka's mother. But a traitor of the Vulcan race helped invaders enter the world. In return for gaining entry into Aries, they ganged up on Taka's mother and killed her.
