Anime suggestions plz?

I want something like Yu Yu Hakusho, flame of recca, black butler (kuroshitsuji), or Slayers. It can be extremely violent and gorey, or it can have tons of cause, I don't care. But, it just cant be hentai or yaoi or yuri. It can be a bit ecchi though. Don't suggest DBZ or One piece or Naruto or Bleach plz.
