By "messed up" I mean when something shows things your generally never shown. For example, usually when an army pillages some place in some story somehow nobody gets raped. But every now and then there comes a piece of fiction where they're not afraid to say/show/depict the fact that people are raped, that is what it actually means to pillage. Also if you want nightmares Eden of the East has a person referred to as the Johnny Hunter. Now if that isn't nightmare fuel I don't know what is. Make sure you don't read a certain manga to do with a certain panda... If anybody gets this you are a sick bastard, lol.
