True agency in isekai resides in the source of power rather than its scale. Comparing a YPS-7 physical entity to a YPS-1 authority user renders standard power metrics meaningless because they operate on divergent axes of influence. While one rewrites the laws of physics and the other exploits the laws of a game, the real divergence lies in their DNA Ego profiles. Han Li represents a complete triumph of self-determination, evolving from a farmer with mediocre spiritual roots into a cosmic architect who dictates reality. His trajectory is a linear ascent toward total autonomy, where every resource gathered and every risk mitigated serves the goal of escaping external control. Conversely, Sora operates as a high-functioning prisoner of the system. His intellectual dominance depends entirely on the existence of rigid rules; without the Ten Pledges of Disboard, his authority vanishes. His low Ego score reflects a fundamental dependency, not just on Shiro, but on the game-state itself. One character breaks the cage to build his own universe, while the other becomes the master of the cage without ever questioning the bars. This reveals a critical genre distinction: xianxia views power as the means to transcend the system, whereas game-based isekai often treats power as the ability to optimize within a system. The gap between a world-ender and a human is irrelevant compared to the gap between one who owns the rules and one who is owned by them.
