The disparity between a YPS-5 continent-level entity and a YPS-1 human renders traditional power scaling irrelevant. This comparison is not about combat output, but about the nature of dependency. Both characters share a zero-score in Ego, yet the origin of this void differs fundamentally. Mile's lack of self-determination is a choice—a desperate attempt to blend in by suppressing an innate, overwhelming authority. She exists in a state of perpetual self-censorship, where her only real action is the denial of her own nature. In contrast, Shiro's dependency on Sora is a psychological necessity, a vulnerability that makes her intellectual dominance fragile. Shiro's trajectory is defined by the tension between her genius and her social paralysis. While Mile spends her narrative trying to shrink, Shiro is fighting to expand her world beyond the safety of her brother's shadow. The narrative weight shifts heavily toward the YPS-1 tier here. Mile is a solved puzzle; she is a god pretending to be a girl. Shiro is an unsolved problem, a human navigating a surreal landscape where her intellect is a weapon but her heart is a liability. The true conflict in this pairing is not between power and wit, but between the boredom of omnipotence and the terror of vulnerability.
