True agency in isekai subordinate roles depends not on the level of power, but on the price paid for loyalty. When comparing a YPS-5 general to a YPS-4 sovereign, the gap in raw destructive output is irrelevant compared to the chasm in their moral costs. Benimaru’s transition from Ogre prince to Minister of Defense is a luxury of alignment; he fits into Rimuru's system because his desires—martial authority and order—align with the state's needs. His low Darkness score reflects a path of least resistance. Raphtalia, conversely, navigates a trajectory of high Growth fueled by a high Darkness score, proving that her loyalty is a conscious act of reclamation rather than a natural fit. While Benimaru finds fulfillment in the hierarchy, Raphtalia must dismantle her identity as a slave to function within one. The comparison exposes a genre blind spot: the "loyal right hand" is often a placeholder for a character whose internal struggle is entirely decoupled from their combat tier. Raphtalia’s ascent to the Heavenly Emperor of Q'ten Lo is a political necessity that highlights her low Ego, whereas Benimaru’s role as a general is a personal preference. Loyalty for the former is a tool for survival and healing; for the latter, it is a professional optimization.
