If you are unable to read the title in-full, I apologize, but it is one of those jokes that is best told in the original language from which it is derived.
The title above is a play on the title of the film Gangs of New York. I’ve replaced “New York” with “乳良ーく” which sounds very similar to New York when spoken — Nyuu Yooku. In truth, this is a nonsense title; it literally means “breasts really great” and even native Japanese speakers will not catch the joke unless they first understand the nuance of what I was trying to share here.
The image at the very top is the inspiration for my little pun. It is from a new Japanese browser game at DMM.com entitled The Gangs of Heaven. Your goal? Run the most perverted gang in all of Tokyo. (You will need to understand Japanese to register and play.) I thought my title was better.
