True agency in the YPS-4 tier is not about the ability to dismantle a national army, but about who owns the will behind the weapon. While both characters operate at a nation-level destructive ceiling, their DNA profiles reveal an inverse relationship between capability and autonomy. Alpha manages a global economic empire and a shadow military with clinical precision, yet her Ego score of 0 reveals a total vacuum of self-determination. She functions as a primary administrator who converts her immense capacity into a mirror for Shadow's perceived genius, choosing to be a tool because she views her own identity as inferior. In contrast, Emilia's trajectory is a slow, painful crawl toward the autonomy Alpha discards. While Emilia faces systemic hatred due to her resemblance to the Witch of Envy, her narrative is defined by the reclamation of a stolen identity and the gradual assertion of her own will. The divergence is most stark in the Darkness dimension; Emilia carries the moral weight of a century of isolation and the pragmatic cruelty required by the Royal Selection. Alpha remains morally shielded because she delegates the burden of ethics to her master's imagined plan. This comparison proves that identical power ceilings create opposite narratives. One character uses nation-level capability to erase herself in service of another, while the other uses that same scale to carve a space where she can finally exist as an individual.
