A lot of those demons look like some of babilis students and teachers, like balsam's dad, lied's dad( i believe he's his dad because he looks young unlike balsam's dad), that demon women looks like the teacher that was attaked by a misfit student in the entrance ceremony!, the clan that had to cast spells on the cage of lied's dad looks like that teacher who can measure powers and emotions and he's a evidols fan, that 13 crowns warrior looks like the demon who was disguised as teacher and had 6 hands and tried to kidnap Iruma
Almost all those demons are a relatives to the demons we see in Iruma's time line, i love it!!! ლ(´ڡ`ლ)
