By forming a contract with a demon and using the power of a demon through a guardian who was its familiar, one could wield power equal to that of a demon, control magical energy rivaling that of a high-ranking demon in a human body, and surpass even the highest-ranking Magi in magical skill. Such a being could stand on equal terms with high-ranking demons and even contend with the very best among vampires, who were hailed as the strongest demons—the Witch.
As the price for obtaining that power, every one of them had to pay the reward stipulated when the contract was formed, without exception.
For example, Sendougi Yuma's price was freeing the Prison Barrier and internalizing that absolute command, being raised solely to fulfill it. In exchange, she gained the power to control space.
Then, Nangong Natsuki's skills surpassed even Sendougi Yuma's, making her a demon hunter feared by the demons of Europe. Even Luo Zhen did not dare claim that his Space Control Magecraft surpassed Natsuki's in level. To obtain such power, just how great a price had Natsuki paid?
One had to understand that a Witch's power and guardian both depended entirely on the price paid. The greater the price, the greater her power—and the stronger the guardian, the embodiment of the contract, would be.
Natsuki's Ring King possessed enough power to destroy Kageno Island with a single blow, nearly rivaling a progenitor-class familiar. It had even earned the respect of Vatra, who was said to be the closest to a progenitor, and its strength approached Vatra's. To gain such power, how could the price Natsuki paid possibly be small?
In the past, Luo Zhen had wondered what price Natsuki had paid to obtain the power she possessed now.
That mystery had finally been revealed.
