Looking for dark mangas

Supernatural with demons or angels, beasts
or just plain evil semes or ukes
like Honjou's ones
and if Im not asking much, not dark/pink please, like a succubus suddenly being all corny,
I want something like Crimson spell or Yokubou no Shizuku or something like Chemestry lab or Kibishiku aishite
or maybe a yaoi kind of shonnen
kind of like Kizuna or Crimson Spell
please no shonen ai....I cant stand shonnen ai :$
thanks
