I hope this is the right place to ask for suggestions.
I'm looking for an anime that has a perpetual, perhaps overbearing sense of despair, misery, doom and gloom and all that fun stuff. I want scenes of comic relief or general silliness to either be non existent or kept to an absolute minimum. I'm thinking elements from Paranoia Agent, Madoka Magica, Attack on Titan and, like, the opposite of Space Brothers.
Started watching Elfen Lied today and I'm up to episode 5. All of the romance/drama crap is turning me off and the violence isn't really doing anything for me, but I might as well continue watching.
