Comparing divine authority against primordial physical force renders a direct YPS scale analysis irrelevant; the gap between a YPS-3 city-level nuisance and a YPS-5 continent-level deterrent is a category error. Instead, the real tension lies in their inverse relationship with servitude. Both possess stagnant Growth trajectories, yet they occupy opposite ends of the psychological spectrum regarding their status. Aqua holds the title of a goddess but lacks the discipline to utilize her authority, turning her divinity into a liability that creates chaos for her party. Her existence is a critique of the divine guide trope, proving that raw capacity without competence is merely a source of collateral damage. Conversely, Diablo possesses terrifying autonomy but chooses total submission. His obsession with Rimuru transforms his primordial nature into a bureaucratic instrument. While Aqua struggles to adapt to a world she views as beneath her, Diablo adapts his entire identity to fit the mold of a perfect butler. This reveals a fundamental divide in how the genre handles non-human entities: power is either a punchline that exposes a character's vanity or a luxury that allows a character to find purpose in absolute loyalty. One is a goddess who cannot serve; the other is a demon who exists only to serve.
