The utility of a YPS rating collapses when comparing a YPS-1 narrative anchor to a YPS-7 reality-warper; measuring their combat potential is a category error. Instead, the real friction lies in their shared maximum score in Bonds, which reveals two opposing philosophies of isekai survival. For one, social connectivity serves as a passive defense mechanism. By obliviously dismantling "doom flags" through genuine kindness, the narrative transforms a lack of agency into a strategic advantage. This is an isekai of assimilation, where the goal is to fit into a social fabric so tightly that the world cannot discard the protagonist. Conversely, the other uses bonds as an exclusive fortress. The transition from a betrayed classmate to a god-slayer in the Orcus Labyrinth replaces social integration with absolute selectivity. Here, bonds are not about harmony but about the fierce protection of a chosen few against a rejected world. While one character survives by becoming the center of everyone's world, the other survives by building a world that contains only those they trust. This contrast exposes the genre's divide between the "social isekai," where power is the ability to be loved, and the "power fantasy isekai," where power is the ability to ignore everyone else.
