Recommend me an Anime

I've seen so much anime It feels like there aren't any good ones I haven't seen so I decided to ask the people of this site like usual. (I'd prefer it to be horror and whatever else with lots of blood and gore) but anything good works for me.

If you havent seen Gundam 00, you should definitely watch that. Even if you dont kno much about gundam you should enjoy it

Noragami, Haikyu, Another and.. Hmmm. I don't really know that many horror animes. Although I definitely agree with Gundam 00--it's really good as well.

Berserk is not in your seen list. I would recommend new movies over TV-series. Definitely has blood and core and some horror elements. Horror series, without blood and core but a neat idea, would be Hell Girl. However, I would only recommend the first season.

for blood and gore there is Elfen Lied, though it may not be as bloody as you want. For a good anime I recommend you to watch Steins;Gate, Baccano, Durarara.
