I am now positive that the sonichu demon is actually Legion.
With each victim, a piece is stored away and it becomes part of the whole. They are many. They are indeed Legion.
Here, in it's latest victim, an individual formerly known as Nicholas Rekieta, we see the manifestation of both CWC and Ralphamale, both former hosts of Legion.
Sadly, there's no cure possible, since the demon was smart enough to possess a jew, so crosses and holy water are ineffective. It all runs off him like water off a raincoat. But call him a meme laywer and you will be astonished at how he recoils, how injured he is, how he suddenly shrinks back: "I’ve been found out".
