The utility of social gravity far outweighs the utility of physical durability in the isekai survival loop. Because these characters operate on entirely different axes—narrative redirection versus physical attrition—the gap between YPS-1 and YPS-2 is effectively meaningless. While one functions as a sentient shield, the other functions as a social black hole. Darkness exists as a specialized tool within a party, her YPS-2 status manifesting as an ability to absorb punishment that would kill a normal human. However, her Ego score of 0 reveals a character who is a passenger in her own story, defined by her reactions to external stimuli rather than her own will. In contrast, Catarina transforms her environment through an aggressive expansion of Bonds. By treating "doom flags" as social puzzles to be solved, she replaces the need for combat power with a network of unconditional loyalty. Her Growth score of 100 reflects a complete psychological pivot from the original game's antagonist to a centripetal force of kindness. Where Darkness finds satisfaction in being a victim of circumstance, Catarina actively dismantles the circumstances that would make her a victim. This comparison reveals that isekai power is often a choice between being the hammer or the magnet; the magnet survives longer because it convinces the hammer not to strike.
