Ichiro, cousin to Naoko, sports a black bowl-shaped haircut and wears a blue long-sleeve shirt printed with "Heavy," fuchsia shorts, and gray shoes. Generally quiet and reserved, he occasionally becomes talkative and openly voices his thoughts. Elizabeth, a rattlesnake puppet requiring manual operation, accompanies him frequently; she mocks and complains about him while also insulting others, often targeting their appearance. Despite Elizabeth’s provocations—and her identification as "the Ichiro snake"—Ichiro remains associated with her. His name is a common masculine designation in Japan. He features in episodes centered on their dynamic: "My Cousin and the Snake" and "My Cousin and the Snake Return."
