As of this startling revelation, I noticed something peculiar: Mimihagi has one pupil, Pernida has two pupils, Yhwach has three pupils in each eye, Soul King has four pupils in each eye. It seems there's a sequential numbering of pupils which represent facets of the Soul Kings power; Mimihagi can take organs and extend life, Yhwach can give/take power and foresee the future, Soul King can foresee the future and regulates the influx of souls in transit, etc. I guess we'll just have to wait next week to see what Pernida can really do. Surely it can do more than just manipulate a person's nervous system.
