Power in isekai often functions as a mask for a total absence of agency. Because these characters operate on different axes—Mathias through physical manipulation and Mile through systemic authority—comparing their YPS-4 and YPS-5 rankings is a category error. One optimizes the world's laws via dust explosions and vibrations, while the other exists as a cosmic glitch that transcends them. The meaningful comparison lies in their shared zero-score Ego: both are prisoners of their own capabilities. Mathias is a slave to a clinical obsession, treating his second life as a corrective experiment to fix the incompetence of a regressed world. His drive is not self-determination but a rigid adherence to a lost science. Mile, conversely, is trapped by a cosmic misinterpretation, forced into a permanent state of self-suppression to avoid breaking the world around her. While Mathias seeks to restore a lost peak, Mile desperately tries to hide a peak she never wanted. This reveals a cynical truth about the genre: whether power is earned through reincarnation-engineering or granted by a divine mistake, it replaces the character's will with a predetermined function. The overpowered protagonist is not a master of their fate, but a tool of their own archetype, whether that tool is a precision instrument or a blunt force weapon.
