True agency in an isekai setting is measured by the distance between a character's function and their will. Comparing a YPS-3 physical combatant to a YPS-1 authority user renders traditional power scales irrelevant because their abilities operate on different planes of existence. Lugh Tuatha Dé operates through destructive output, while Sora operates through systemic manipulation. The meaningful tension here is not who wins a fight, but who owns their own existence. Lugh presents a facade of total control, yet his high Growth score reflects a clinical optimization of a tool rather than a liberation of the self. Even when utilizing 'My Loyal Knights' to build a support network, he treats human connection as another variable in a tactical equation to fulfill a mandate. In contrast, Sora's low Ego score is a transparent admission of fragility. He does not pretend to be a self-sufficient agent; he explicitly ties his identity to Shiro and the rigid laws of Disboard. Lugh is a man attempting to manufacture a soul from the ruins of a professional assassin's mindset, whereas Sora is a genius who accepts his limitations to exploit the loopholes of reality. This reveals a core genre dichotomy: one character seeks to escape the role of a tool by becoming a master of efficiency, while the other finds power by leaning into a specific, shared dependency. Lugh's struggle is against his own programming, while Sora's struggle is against the boredom of a world he has already solved.
