Agency defines the difference between a tool of destiny and a master of reality. While the gap between YPS-6 and YPS-7 suggests a quantitative difference in output, the real divergence lies in the relationship between power and will. One character views cosmic capability as a hard-won shield, forged through millennia of calculated risk and the overcoming of False Spiritual Roots. This path transforms a mortal into an architect of physical laws, where every single point of Growth represents a conscious choice to survive. In contrast, the other exists as a born catastrophe, possessing planet-level destruction as an innate trait rather than an achievement. This creates a fundamental stagnation; when power is a birthright, Ego collapses. The search for "fun" and the reliance on external figures like Rimuru are symptoms of a character who possesses the means to destroy worlds but lacks the internal drive to define her own existence. The comparison exposes a brutal truth about the isekai power fantasy: innate divinity is a gilded cage. True autonomy requires the grueling climb from the bottom, where the cost of Darkness is paid in exchange for the ability to say "no" to the universe. The disparity in Ego scores reveals that a YPS-7 status achieved through effort is fundamentally different from a YPS-6 status granted by blood. One is a survivor who conquered the system; the other is a system that forgot how to be a person.
