The gap between authority-based influence and physical mastery makes a direct YPS comparison irrelevant. Demiurge operates at YPS-4, manipulating geopolitics through the facade of Jaldabaoth, while Eris functions at YPS-3, focusing on the tactile precision of the blade. This is not a clash of power, but a clash of purpose. Demiurge is a static entity; his growth is a delusion projected by Ainz, where his efficiency is simply the execution of a pre-existing program. In contrast, Eris defines her entire existence through the agony of improvement. Her departure from Rudeus to endure the brutal training of the Sword God represents a rejection of the supportive role typically assigned to isekai female leads. While Demiurge treats humans as raw materials for parchment, Eris treats her own body as raw material to be forged. One embodies the horror of a perfect machine, the other the struggle of a flawed human. Their DNA profiles reveal the core tension: Demiurge's high Bonds are based on absolute servitude, while Eris's Bonds are the catalyst for her personal evolution. In the isekai landscape, Demiurge shows how power can be a cage of expectation, whereas Eris proves that power is the only way to break a cage of inadequacy.
