Satomi, a wealthy student attending the same elementary school as the main protagonists, embodies the quintessential "rich girl" archetype with a perpetually haughty demeanor. As a recurring antagonist in school-centered conflicts, she habitually stirs up trouble through calculated acts of superiority, targeting those she deems beneath her social standing. Her bullying tendencies peak in documented instances like harassing a junior student, an act that provokes another character to openly challenge her behavior—exposing her reliance on social hierarchy to enforce dominance. Unwavering in her elitism, Satomi maintains a rigid aura of entitlement, consistently leveraging her status to assert control while reinforcing her role as a persistent source of friction within the school’s social dynamics.
