So was Elmir really Persona like he claimed to be, or was it merely more Omega-memory shenanigans? At first I thought he was another host to Dark Falz Persona like Margaretta and Gettemhult were hosts for Apprentice and Elder respectively. But later dialogue by the player seems to refute this. His personality also doesn't match Persona's, since Persona's obsession is trying to "save" Matoi.
So who is he then?
