wanting anime like ao no/blue exorcist T.T something that's ACTUALLY like it?

im simply lusting for something similar to ao no exorcist!!! ive looked up what other people recommend and most of them have been awful! i really want n anime with that same shonen feel with some good comedy but loads of serious stuff in it, obviously has to be themed around demons, vampires or similar etc. ive watched most of the main stream anime like naruto an so on. just please!! ANY recommendations that are not on my myanimelist linked below (non of he ones in want to watch tickle my fancy right now)

i have ended up watching some anime and then going back to blue exorcist over an over an have watched it from start to finish 7 times now, just cant get enough!!

this is what ive watched that people have said it was like

dead man wonderland - hated every moment of it! dunno why people said it was like ane, only good thing about it was the intro song

high school dxd - -good story but dropped it after a couple of episodes cause the constant and unnecessary focus on boobs and up skirts really put me off, no one said it was a bit ecchi

buso renkin - loved it but i just didn't warm to it as much as i did ane

blood c - i did enjoy this but i didn't get the thrill i did from ane

ANYTHING would be great!!

thanks =)
