Killing Stalking
Before you even start to think about reading it, here comes the triggers (you should know before reading): Stalking, female and male nudism, straight and gay Sex, choking, torture, hallucinations, forced suicide (?), mutilation, self-mutilation, dismemberment, lots of blood, use of chains, attack on/by family member, rape, murder, mental illness, general abuse, willing incapacitating others, general body fluids, heavy verbal depreciation, humiliation. After knowing that you may find those and more, if you are still willing to read, I highly recommend i, since it is an actual thriller,it gets you on the edge, it's dark, scary, ducked up, but extremely well written and down. Depending on your personality you may not even hate none of the characters (I do not hate any, but I pity all with no exceptions)
Apocalypse No Toride
It's been over a year, and I'm not even close to be over some deaths and this fucking ending
Shuuen no Shiori
So, this is freaking amazing, I love all the characters, someone picked it up again (after almost two years, but that's fine). This is extremely pleasing to read if you like urban legends (I'm fine with gore but weak to them, so I found this extremely disturbing/scaring). Worth my while.
Gesshoku Kitan
Horror AND yaoi? Hell yes, count me in! Like wow! I love the art, like, I actually really love it. And suddenly there's a kiss and then there's a murder and then WOW!! I may be enjoying (and hyping) this way too much but I REGRET NOTHING!
Pet Shop of Horrors
This! Is! ART! My new baby favorite.
An Uncomfortable Truth
One of my most favorites
Sabi no Yume
Edit: looking back on it... Yeah, not that good MC is asked to test a sex toy, that is made from a dead kid's body. He tests it profissionally (no sex or self-satisfaction usage). They robot seems to be unable to speak and only obey commands but after receiving the smallest of the caring he seems to starstruck by this behaviour towards him that he never felt. This manga is probably going to follow the line of robot discovering feelings and the line of what is and what isn't morally okay. Hopefully we will have a lovely ending or a tragedy but good ending.
Juveniles
Not yaoi but the plot is wow, art is beautiful and is a psychological fantasy.
Save Me
The fucking best. Finished re-reading it. Still one of the fucking best.
