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 "three people would make four legs," she couldn't understand at all, convinced that it was just an idiom. It wasn't until the director Chi-chan explained it with a drawing that she finally learned what a three-legged race was.
