Everything about my O.C.s

Background Info

All of my characters live in the same place (besides side characters). At this point, I'm unsure whether to make them all live in the same small apartment complex or live on the same street but in different houses. Besides that, everything else is pretty true to the story and is consistent throughout the whole making of my characters. 

Hell or the underworld is a real thing but has nothing to do with religion. I just needed a place where demons come from. Demons are a big part of my world but act as just another type of person. There's a lot of lore behind demons since the normal world acts as the real world. I'll have to make another entry for the lore behind demons and things about them. 

I've always seen the school (high school specifically) in this universe as being very corrupt, as well as Ellie and her gang or friends being a vigilante. They would essentially kill corrupt adults. This idea is fun and might be kept but I'm on the fence about this. It comes down to 1) how does Ellie and her friends get away with this and 2) how Ana, Ellie's adoptive mother, would react to this. This'll have to be worked on if I want to keep it, but if anyone has any ideas for this, let me know in the comments. :)

I'll make specific chapters about each character so it'll be nice and neat. These chapters won't be in any specific order, but I do pair up my characters with one another. An example of this is when I'm drawing, I'll draw one of them, then draw their pair after that. The pairing system is like this: Lillie and Vi; relation: siblings. Fay and Sylv; relation: married. Ana and Ellie; relation: mother and daughter. The side character will also be paired with their counterparts but this is the main six. 

This is all the basic information for understanding the world (besides the underworld/hell).
