In Japanese, a three-legged race is called ni-nin san-kyaku (lit. "two people, three legs"), and the phrase is also used idiomatically to mean "working together in cooperation."

During Neon's first solo stream, she referred to the three members of her unit working together as san-nin san-kyaku ("three people, three legs"), which confused the viewers. Even when they pointed out that "with three people, it would be four legs," she was completely baffled, convinced that she had merely played on the idiom a bit. It wasn't until the director Chi-chan explained it with a drawing that she finally understood what a three-legged race was and what happens when there are three people.
