what are some good as shit horror manga? I wanna get really scared

Ito really has a monopoly on "absolute horror" manga, everything else that I've read has horror elements sometimes, but isn't horror exactly. Dunno if you'll find another manga like that.
The only thing even remotely close that I can think about is Berserk, which has some pretty messed up parts.

I asked me m8 about horror manga a while ago
he mentioned one of either Parasyte or Terra Formars as examples of horror done right in contrast to Tokyo Ghoul

Kago Shintaro is more creepy than horror to me, but could work for some. Horror in his work is part of the prevailing surrealistic approach he has in his art.
