They made it sound like split personalities in the beginning. In that case, they are all mugo.
Honestly after reading a bunch of fantasy books where there are multiple snakes that have more than one head I’m starting to think that this personality disorder is just another way of saying mugo is a snake with 3/4 heads
So there are 4 mugo,so who is the real mugo among them,there has to be the one who's the owner of the original body
