True agency in isekai is often masked as competence, but the overlap in these profiles reveals a stark divide between submission and systemic efficiency. Because this comparison pits a YPS-4 physical combatant against a YPS-7 hybrid entity, any attempt to quantify their combat output is a category error. The meaningful metric is the shared zero-score in Ego, which functions in opposite directions for each character. For Alpha, this absence of ego is a psychological prison. She constructs a global economic and military hegemon not for her own ambition, but as a desperate bid for validation from a master she fundamentally misreads. Her competence is a mask for an internal void, turning her into a high-functioning instrument of another's perceived will. Rimuru, conversely, utilizes a lack of ego as a strategic asset. By discarding traditional human pride and malice, Rimuru transforms from a protagonist into a bureaucratic engine. The evolution into an Ultimate Slime is not a personal victory but a systemic upgrade that allows for total geopolitical engineering. While Alpha is a person attempting to be a tool, Rimuru is a tool that has successfully replaced the need for a person. This reveals a cynical truth about the genre: absolute power is achieved only when the individual is entirely erased, whether through the tragedy of devotion or the cold logic of administration.
