Not really dark/horror to begin with, but one of the craziest endings in an anime series has to be from "School Days". Starts off as a bit of a romance-themed anime, then takes a huge twist.

"Higurashi no Naku Koro Ni" and it's sequels/spin-offs. Might get a bit confused, but it's definitely insane.

"Tokyo Majin Gakuen Kenpucho: Tou". Hard to describe. Reminds me a bit of the Shin Megami Tensei games. Gist of it is about the "reborn dead".

Other mentionables... "Gantz", "Elfen Lied", "Paranoia Agent" (Maybe), "Claymore"...

Could watch the "Ichi the Killer" one-shot anime. Or the live-action movie. Same goes for the "Battle Royale" live-action.

That's all I have for now.

Edit: OH. Dunno how I forgot "Deadman Wonderland" ;-; That's one of my favorites. I second that recommendation.

You have to watch mirai nikki. It has the craziest, wierdest and creepiest characters ever. It's not really a horror, but it does give you the creeps. There is also a lot of gore, echi and violent scenes if you like those kinds of anime. The plot is really interesting and the ending is so good :)

I hate while human beings merely ask to advise an anime, thank you for being so precise ^__^ Now, enable me see...>.> ... <.< ...^.^...v.v... i know! Watch this Anime: - D. gray guy (it is likewise my 2d admired anime, 1st being One Piece) >> Episodes : 103 >> My score out of a 10: 9/10 >> Uhm...hi! lol i'm nonetheless going to assert: This teach is incredibly solid! crammed with awesomeness!!! precis: Allen Walker is a youthful Exorcist who has a cursed eye that could see the suffering of the Akumas created by making use of The Millenium Earl. He travels to England to the Headquarters of the Exorcists the place his grasp has despatched him to fulfill with the different Exorcists. The conflict with the Millenium Earl and the Noah relatives vs. the Exorcists intensifies while the various appropriate Exorcists start to get killed by making use of hoards of Akuma. Japan takes middle degree in this end of nineteenth Century plot with the intention to no longer enable the full human race be became into Akumas and the Exorcists be able of "Innocence" that replaced into given to them by making use of God on their element. What i like: i in my view like the story a lot. The Millenium Earl is the main suitable enemy who makes use of human beings's sorrow and dying souls to make the Deamons (Akuma). The Exorcists job is to wreck those akuma and save the souls. i like this plot and all, and that i like how the Akuma are in a position to take over a human and act as a human to no longer be observed. this is creepy and funky. The Exorcists all carry divine ability called "innocence" which i think of is marvelous, all of them have a various unique ability that replaced into given to them by making use of God. in addition they conflict against the Noah, a team of persons who're alongside the Millenium and his military of Akuma. What i do in comparison to: properly there won't be a lot i do in comparison to..perhaps the fillers are slightly demanding. And the akuma are demanding I wish they might die lol yet so do the Exorcists. what I hate is they did no longer end the Anime thoroughly, however the manga remains ongoing the place the anime left off and that i choose the manga too. although that's an exceedingly solid anime, you're able to provide it a attempt. i'm constructive you will like it. It has what you're soliciting for: action, Blood, and Comedy ~~(^__^)~~
