Comparing a physical combatant to an authority-based entity renders YPS tiers functionally irrelevant. Filo operates at YPS-2, while Satou exists at YPS-7; this gap means any direct comparison of capability is a category error. The real insight lies in their shared Growth score of 100, which reveals a fundamental divergence in how the genre treats evolution. For Filo, growth is a trajectory of emergent sentience. She evolves from a mindless monster into a Filolial Queen, moving from a tool of the Shield Hero to a partner with her own emotional weight. Her growth is an ascent into personhood. Satou uses his growth to achieve the opposite: invisibility. He leverages his vast capacity for improvement not to climb a social or political hierarchy, but to construct a domestic sanctuary in Labyrinth City. While Filo grows to claim a place in the world, Satou grows to curate the world from the sidelines. The disparity in their Darkness scores emphasizes this tension. Filo’s zero-cost growth reflects her role as a symbol of purity and loyalty, whereas Satou’s higher moral cost stems from the detachment required to treat a living world as a sandbox. One evolves to become a protagonist in her own right, while the other evolves to become a benevolent, invisible landlord.
