Basics and grounding/Character information

There's a lot of information here and it's all pretty good to be honest with you, though I might be pretty biased due to my love of demon characters that break the expected molds. Maybe just build off of her already existing personality and maybe add to her hobbies a bit more and a bit more development and she should be good to go.

Relationships

So I don't really know which characters here are original or from the franchise (except Annabelle), but I'm fine with relationships with canon. Really just develop this further and add more detail to make these feel realistic and well fleshed out more.

Backstory

Since this was in an oc book, I'll let this slide but it'd be useful to know her Backstory to accurately judge her.

Other

That's a lot of powers but since it's a demon you can get away with it, but be careful with it because we don't want her being two op.

Stats
There was no stats so I definitely recommend coming up with some because they act as a really good grounding for some character aspects.

Extra

Cool cool, not much to say here.

Final thoughts
This is a pretty decent character and all I can really tell you to do is develop her further and add to her so you can build up from what you've already got. Apart from that, good job.
