RT5 (the "King") believes that the trait inherent in humans capable of subverting the calculations is freedom, a concept that they have always found most difficult to understand. The resolve to pursue freedom leads them to reject the consciousness link, to refuse to become one and be measured as a whole.
RT6, on the other hand, believes that the answer to this problem lies within the "Emperor".
Or more accurately, in her process of spending day and night with the "Emperor", embarking on a journey together.
Perhaps in the focal point of this hero versus Demon King-style journey, the children will find the answers they seek.
