I would say Beelzebub, but the people don't look like demons. Maybe Soul Eater. See Soul's inner demon. He wears a suit. Soul Eater does not have many demons.
You pretty much have all of the animes I watch.
FMA doesn't really have demons same with Death Note. Ao No Exorcist is only 26 episodes long and atleast 50 % of it is lame fillers and the author does not seem to understand that Japan is not a good place to have a Christian themed anime and he also does not seem to understand the difference between a youkai and the Christian demon.
The author is a woman for Blue Exorcist. See Kazue Kato. Just to edit your comment.
Cool! Most people tell me to read the manga version of Beelzebub since the anime is diverting a bit from the storyline. (Not to spoil you).
I know you wanted a light hearted anime, but I want to suggest Supernatural based on the tv show on the CW. I haven't finish watching it, but the first two episodes are bizarre, violent, and tearful.
I heard of Shounen Onmyouji that has demons as the enemy, but I never watch it. Did you watch that?
