At Frankenstein's lab, Frankenstein explains to Tao and Takeo how powerful the Nobles are in order to reduce their inferiority complex after fighting Rael. Nobles are the longest living race on earth. Even the Union, the oldest human organization, would be incomparable in terms of noble power. The unique abilities of mind control and long lives make it hard to oppose them. Rael, who ages above 500 years, is an adult noble who has realized his full powers. So, it is but only natural that there is a huge power difference between him and Tao, Takeo who didn't even fight with their specialized weaponry. Also they have yet to realize their full potentials. Apart from that, the location also plays a vital role influencing combats; e.g. in the school ground, they had to be careful not to use much power. It's like fighting the worst possible opponent, in the worst possible way at the worst possible place. But from now, Frankenstein, himself, will look into their physical condition and the two have no other option but to agree to whatever he says.
