True agency in a gamified world is found not in the accumulation of power, but in the deliberate restriction of it. Comparing a YPS-3 physical caster to a YPS-5 authority-type is fundamentally flawed because they operate on different metaphysical planes; one generates destructive force while the other manipulates the laws of existence. However, their narrative functions converge on the concept of the "cap." Megumin’s limitation is a manifesto. By rejecting versatility for the singular Path of Explosion, she transforms a tactical liability into a core identity. Her growth is not a climb in power, but an expansion of her social Bonds, proving that chosen incompetence is a valid form of rebellion against the genre's obsession with optimization. Mile represents the opposite pole: forced mediocrity. Her restriction is not a choice but a survival strategy born from a cosmic error. While Megumin fights to be seen for her one trick, Mile fights to remain invisible despite her omnipotence. This creates a stark contrast in their DNA profiles. Megumin’s trajectory is an ascent toward acceptance, whereas Mile’s is a horizontal line of containment. One uses a limitation to construct a self, while the other uses a limitation to erase one. In the end, the YPS gap is irrelevant because both characters serve as critiques of the "average" protagonist: one finds freedom by refusing to be useful, and the other finds a prison in being too useful to exist.
