Loyalty in the isekai framework functions either as a catalyst for liberation or a mechanism of systemic stagnation. While both characters occupy the role of the devoted subordinate, the distance between a YPS-3 spirit and a YPS-4 demon reveals a fundamental divergence in how agency interacts with devotion. Beatrice begins as a prisoner of her own directive, her low Ego score reflecting a centuries-long paralysis. Her growth is not measured by the expansion of her mana capacity, but by her decision to abandon the purgatory of waiting for "That Person" to embrace a messy, fragile partnership with Subaru. In contrast, Demiurge possesses a higher baseline of self-determination, yet his agency is a closed loop. He does not grow because he is already the perfect instrument of Ainz Ooal Gown's perceived will. His intelligence is not a tool for self-actualization but a means to refine the cruelty of the Sorcerer Kingdom's administration. Where Beatrice uses her bonds to climb out of a hole, Demiurge uses his to build a more efficient dungeon. The power gap here is less about destructive output and more about the direction of their trajectories. Beatrice moves from a static object to a living subject, whereas Demiurge remains a high-functioning extension of another's shadow. One transforms through the vulnerability of needing another; the other reinforces his existence by erasing the needs of everyone else.
