What is nigo in English?

"Nigo" is a Japanese name, often written in katakana as ニゴ. It can be a first name or a surname. There isn't a direct English equivalent, but it's often translated as "Second", as the character "二" (ni) means "two".

However, "Nigo" is also the name of a famous Japanese fashion designer and the founder of the streetwear brand A Bathing Ape. In this context, it is not translated and is simply his name.
