I just thought I'd start this since there's already one about the most depressing.
hm. I guess Jisatsu Circle creeped me out. but it was more gory than scary.
I've only read a chapter, but for some reason meisou kuiki kinda scared me also.
I try to avoid "scary" manga because I'm already a bit of an insomniac o.o

I'm still scarred from those disgusting scene in Uncivilized Planet, Tropical Citron and Keep on Vibrating

That damn pig!!!

It kinda made me want to rip my eyes out...

Yeah.. when I saw that, wanted to throw up.

Don't think I have a most frightening manga.. Don't really read any suspense or horror mangas. <_<

Could you count MONSTER as one of them?

It has got me a few times.

I thought Zashiki Onna and Ode to Kirihito were quite frightening.

or 20th Century boys.............

oh oh, 7 seeds. That most scariest one yet.....

if you really want to scare yourself.....just take a look at my life. I guarantee you'll cry yourself to sleep.

Both my ignorance and my hidden hatred are overwhelming. Because I hate them all....all of them.....

hey. guess what.
I HAVE A SNOWDAY TOMORROW.
the super of my district is from canada or osmething so we /never/ have snowdays.
you may think that was totally offtopic, but it isn't =]
because since I have a snowday tomorrow I'm going to stay up until the early hours (3am-ish)
meaning I can read 'scary' manga without having to force myself to go to sleep.

ive just seen the most frightening manga in the "releases"

Naruto dj - Ninja Ballet Academy Exams
i knew itd be yaio but with the title i had to look at the descript anyway

that image is burned into my mind

               but to really gross you out, did you know pigs can orgasm up to 30 minutes?    

           hmmm, i am pretty frightend of shoujo,        the thought that some people actually think like those manga characters drives me into dispair

I really did not need to know that thing about the pig.
Actually, it would be an interesting conversation starter xP

&&I smite you, evil shoujo hater.
even though I guess I agree most shoujo is so cliche it makes me want to stick a toothbrush down my throat...
but there are a lot of great ones too.
