Agency is inversely proportional to inherent scale when comparing an evolved warrior to a primordial entity. The gap between YPS-4 and YPS-5 represents a shift from earned capability to ontological fact. Asuna’s trajectory is defined by a Growth score of 80, moving from a sheltered student to a tactical anchor who defines her reality through struggle. Her power is a result of iterative mastery and the refusal to be a passive participant in a death game. In contrast, Diablo operates with a Growth score of 20 because his existence is static; he does not evolve, he simply manifests. While Asuna fights to secure a place for herself and others in a digital void, Diablo uses his continent-level capacity to curate a comfortable environment for Rimuru. This reveals a fundamental narrative divide: one character uses power to achieve autonomy, while the other uses absolute power to surrender it. The comparison breaks down at the point of utility; for the former, power is the means of survival, whereas for the latter, power is a prerequisite for a specific brand of obsessive servitude. Asuna's lack of Ego reflects a selfless integration into her bonds, while Diablo's minimal Ego is a calculated decision to replace self-determination with a master's will.
