The disparity in agency defines the difference between a companion's evolution and a protagonist's maturation. A YPS comparison between a YPS-2 Awakened physical fighter and a YPS-3 narrative-driven survivor fails because they operate on different axes of influence. Filo’s perfect Growth score reflects a biological and social ascent from a mindless Filolial to a Queen, yet her zero Ego score proves she remains a passenger in Naofumi’s narrative. Her development is a function of her bond, not her will. Kazuma operates on the opposite end of the spectrum. His Growth is not a climb in stats but a psychological pivot from a NEET escaping reality to a man who accepts the burden of his broken party. While Filo's power is an extension of her master's success, Kazuma uses his high Luck and pragmatism to manipulate the world's systems to his advantage. This comparison reveals a fundamental divide in isekai power dynamics: the difference between the "loyal tool" who scales through association and the "system-breaker" who scales through adaptation. Filo evolves to fit a role, whereas Kazuma matures by refusing to fit the role the world expects of a hero.
