Butaro is an anthropomorphic pig depicted as a sentient being who wears clothing and attends school with humans and cats. He endures systemic discrimination in his environment: pigs are confined to cramped sleeping pens and fed bland rations while other species experience greater comfort. Socially, teachers overlook him during lessons, and peers explicitly shun him due to his species. His personal tragedy includes the slaughter of his family for food, culminating in an incident where his sister unknowingly consumes parts of him posthumously. His character symbolizes marginalization and vulnerability. Personality assessments assign him an ENFP Myers-Briggs type and Enneagram 1w9, reflecting idealism and integrity-seeking traits, contextualized by his harsh reality. His arc concludes when the kittens' father kills him and serves him as tonkatsu to his sister, cementing his victimhood within the narrative's carnivore-dominated societal cruelty.
