True protection in the isekai framework is often a mask for personal indulgence. When placing a YPS-4 powerhouse against a YPS-2 frontline defender, the gap in raw output is secondary to the gap in intent. Darkness embodies the paradox of the tank who desires the hit, turning the act of defense into a private reward system. Her utility to the party is a byproduct of her own internal needs. In contrast, Azusa utilizes her capacity for national-level destruction to ensure that nothing ever happens. She does not protect her household out of a sense of chivalry or a desire for impact, but to maintain a vacuum of peace. While Darkness finds fulfillment in the collision, Azusa finds it in the absence of one. This reveals a fundamental split in the defender DNA: one uses the shield to feel something, the other uses the shield to feel nothing. The comparison breaks down if viewed as a combat trial, as the YPS gap makes a physical confrontation meaningless, but it succeeds as a study in how power is used to curate a specific psychological state. Azusa's 100-point Bond score is not about loyalty to a cause, but the construction of a safe harbor, whereas Darkness's Bonds are the anchor that keeps her tethered to a reality where her desires are tolerated.
