True autonomy in isekai is rarely about the ceiling of one's power, but rather the cost of acquiring the will to use it. While both characters sit at YPS-3, a direct comparison of their capabilities is fundamentally flawed because they operate on contradictory axes: one wields arcane authority and the other masters physical violence. This cross-type divide renders the YPS tier a mere coincidence of output rather than a measure of similarity. Instead, the meaningful parallel lies in how they navigate the gap between their own capabilities and the people they love. Beatrice spends centuries in a state of arrested development, her magic serving as a gilded cage of waiting. Her growth is not an increase in output, but a psychological collapse of the walls she built around her heart to survive abandonment. In contrast, Eris views her initial inadequacy as a physical deficit. Her departure from the Greyrat household to undergo grueling training is a rejection of the role of the protected. While Beatrice finds agency by allowing herself to be vulnerable and dependent on a contractor, Eris finds it by scrubbing away every trace of dependency through the blade. Ultimately, these two trajectories reveal a core tension in how the genre treats female agency. Beatrice proves that liberation can come from the surrender of a lonely ego, whereas Eris demonstrates that liberation is forged through the violent pursuit of competence. One breaks her chains by finding a reason to stay, the other by finding the strength to leave.
