True agency in isekai is inversely proportional to the scale of the protagonist's power. The gap between a YPS-3 tactical mage and a YPS-7 cosmic architect is an unbridgeable void, rendering a direct combat comparison useless. Instead, the interest lies in how the lower-tier character possesses a far more volatile narrative tension. Tanya Degurechaff exists as a study in friction. With zero Luck and zero Ego, her every victory is a desperate optimization of a system designed to crush her. Her battle is not against a physical foe, but against Being X and the suffocating inertia of military bureaucracy. She is a cog that refuses to turn, making her narrative weight heavier than her destructive output suggests. Conversely, Han Li’s ascent to YPS-7 is a masterclass in patience and resource acquisition. While his Growth score reaches the maximum, his journey is a long-term investment strategy. Once he gains the ability to rewrite physical laws, the story ceases to be about struggle and becomes about administration. The tension here is between the triumph of the individual over the system and the individual becoming the system. Tanya’s struggle is more visceral because she remains a victim of circumstance, whereas Han Li eventually transcends the very concept of circumstance.
