Paul, George’s younger brother, exists as a canon character unique to the 1975 anime adaptation. Embodying the exasperating younger sibling archetype, he routinely tests George’s patience with impulsive behavior and tactless comments, shaped by his rural background into a brash, unfiltered manner of speaking. A pivotal river accident—where Nello rescues Paul from near-drowning—cements George’s lifelong gratitude toward Nello, directly influencing their evolving friendship.

Functioning as comic relief, Paul’s guileless inquisitiveness and social obliviousness drive moments of unintentional provocation, such as bluntly inquiring about Alois’s terminal illness. His antics accentuate George’s nurturing tendencies while contrasting Nello’s reserved demeanor. Narratively, Paul underscores familial ties and communal interdependence within the village structure.

Exclusive to the 1975 series, the character appears in no other novel or film iterations. His limited development unfolds through episodic subplots, positioning him as a secondary fixture within the protagonist’s orbit.
