i'm looking for a really creepy manga ; something out of the ordinary, which can't be seen here and there;
more key words: blemish, schizophrenia, murderous mind, sex(any type), violence;

something violent like Battle Royale + something creepy like Homunculus; more creepiness over violence would be better;
something extremely creepy-crawly indeed

apologies if a topic like this was brought up before

Tokyo Akazukin

Edit: for something with a better plot and less creepy, but still violent, I'll say Elfen Lied.

What I like in Trivial Pursuit style. Pick your category:[img]http://i379.photobucket.com/albums/oo233/Reid4891/Manga/trivia-1.jpg[/img]

4th Class Biology (Maybe?)
Bradherley no Basha

I second Tokyo Akazukin

Edit; Also, Ichi the Killer

Does the walker choose the path, or the path the walker?

Shamo

Ima go ahead and also recommend Bradherley no Basha

I second Skyhigh and Skyhigh Karma. To be honest, any of Takahashi Tsutomu's works could fit your criteria.
