Hahahaha! 😀
As soon as you put on a mask, you’ve joined the Kakashi hive mind: Kakashi is all, all are Kakashi.
Maybe it’s a running joke in ANBU–any unidentified masked people are called Kakashi, and while eventually it becomes a sort of “oh, of course, scarecrows that makes sense” the truth is it’s referring to the one, the only, infinite masks himself.
I am now wondering about a Majora’s Mask fusion/crossover, but unsure where I’d go with that…
