Ninjas have pretty much given up even trying since winning the trademark lawsuit in the late 2000’s. With a legal ruling on their side preventing anyone else from effectively practicing anything relating to “stalking” or “hunting” or “stealth” or “assassination”  their competition disappeared and when that district court ruled in 2018 that defending yourself against a ninja attack was unfair competition that was pretty much the end. Why hide if it makes no difference who sees you? Yesterday I saw a ninja passed out asleep at a bus stop. Today I saw a ninja wearing a t-shirt with a brick wall printed on it leaning against a concrete block building. It’s embarrassing.
