The tension between systemic mastery and emotional surrender defines the gap between physical combatants and authority-based entities. Comparing a YPS-4 physical powerhouse to a YPS-3 authority user is fundamentally flawed because their abilities operate on different axes; one optimizes a game's physics while the other manipulates conceptual laws. Asuna utilizes her combat efficiency to seize agency from a rigid system, transforming her high-tier status into a shield for others. Her growth is a trajectory of ascent, where power serves as the vehicle for her liberation from societal and digital expectations. In contrast, Beatrice's narrative function is a descent. Her power is not a tool for liberation but a symptom of her stagnation within the Forbidden Library. For Beatrice, agency is not found in increasing her output, but in the vulnerability of the contract. While Asuna fights to maintain her identity against the game's constraints, Beatrice fights to destroy her identity as an immortal observer to become something small and dependent. This reveals a core isekai dichotomy: power as a means of independence versus power as a barrier to intimacy. Asuna proves that mastery of a world grants freedom, but Beatrice proves that the willingness to be powerless is the only way to truly belong.
