True agency in isekai is inversely proportional to raw output. Comparing a YPS-2 narrative climber to a YPS-5 authority figure is a category error because their abilities operate on different axes; one is a trajectory, the other is a static state. The real divergence lies in how power dictates their social architecture. Iruma’s lack of innate strength serves as the catalyst for his massive Growth and high Bonds. By starting as a vulnerable human in a demon school, he earns his leadership through genuine adaptation and relational weight. His story is an ascent. Mile, conversely, exists in a state of permanent descent. Her authority is so absolute that it functions as a narrative wall, flattening her Growth and Ego to near zero. She does not evolve; she recalibrates. While she protects her allies, her need to maintain the facade of an unremarkable hunter ensures that her relationships remain superficial compared to Iruma's. The YPS gap is a distraction from the actual tragedy: Mile is a prisoner of her own scale. Where Iruma finds freedom in his inadequacy, Mile finds a cage in her competence. This comparison reveals that isekai often treats high-scale power not as a reward, but as a constraint that trades character development for tactical convenience.
