December 31, 201311 yr Mirai Nikki, I think. I've heard a lot about it, and seems to be a pretty freaky anime with insane people and plenty of murder. Hellsing Ultimate also has a horror vibe, with the ghouls and vampires.
December 31, 201311 yr Mirai Nikki Darker than black Higurashi No Naku Koro Ni (Definitely recommend it.) Elfen Lied (Kinda sad but great anime) Attack on Titan (gory but awesome)
January 1, 201411 yr Soul Eater has some horror aspects to it during certain moments, that's all I watch in terms of horror though.
Any recommendations about horror anime/manga?
