I also like this comic:
Demonology 101
It's a little slow in the beginning but it starts to get interesting, it's a little serious at times, but every now and again it has a bit of humour put into it
This comic is about a young demon by the name of Raven, who is going through life and is starting to discover the secrets behind her past, and most importantly starting to converse with humans.
I suggest you read the character profiles first so you know what is going on.
