The gap between a city-level combatant and a planetary force is a void in terms of raw output, but this disparity exposes the fundamental difference between a character who exists to fight and a character who fights to exist. While YPS-6 entities operate as catalysts for cosmic events, the real narrative weight sits with the YPS-3 operative who treats his own existence as a tactical error. Lugh’s journey is a clinical attempt to manufacture a soul from the wreckage of a tool, a struggle far more complex than the infinite loop of self-improvement that defines Goku. The Saiyan’s drive is ludic; he seeks the thrill of the struggle, effectively making him a prisoner of his own appetite for combat. Conversely, Lugh’s high Growth score reflects a desperate, clumsy integration of human connection—seen in his fragile bonds with Dia and Tarte—into a life designed for cold efficiency. Goku possesses an absolute Ego, driving the plot through sheer will, but Lugh’s struggle with a stunted sense of self creates a tension that raw power cannot replicate. The tension between being a "necessary hand" and a "person" provides a psychological depth that becomes diluted when a character can simply erase a planet. In the isekai landscape, the lower-tier character often proves the more sophisticated study because their stakes are internal and existential, rather than external and geographical.
