Anything by Motoni Modoru, really. All her mangas fuck with you on a psychological level big time. She even abandoned one of her mangas becoz it was getting too much even for her.
Dog Style is her only ''normal'' yaoi. Though you WILL bawl your eyes out reading it. :P
Don't remember where I read it but there was this boy and he was tied up and hung from his arms in a (storage?) room by I think three other boys. Main leader of the boys (A) pulled the tied up boy's (B) pants down and hit B's crotch so hard it bent. The two other boys ran away. Long story short, A mutilated B's body (shoved a bat in him) a security guard came in and found B's dead body along with A who committed suicide. (Story is all foggy since I read it way back when and tried to forget about it)

Harada isn't that bad. But it might be because my first Harada manga was: http://www.mangago.me/read-manga/gintama_dj_kabe/

Same... it was my first hardcore yaoi
I was just a newbie in the BL world when I found this manga's cover and thought, "Oh, he's cute. Let's check this out~"
BOY WAS I WRONG
I didn't touched yaoi for like a year┗( T﹏T )┛
So I thank "Beelzebub" and the OgaFuru shippers for bringing me back here ╮( ̄▽ ̄)╭
Well funny enough, when I gained enough experience, I looked back and read this doujinshi again...
I kind of like it now... but it still breaks my heart ╥﹏╥
Hey humans so I was wondering what the most disturbing manga you have ever read is?
Stuff like violence psychological gore rape murder etc..
