I believe we discussed this Log in to see images!

Anyway, School Mermaid is short and kind of spooky. it doesn’t comapre to Ito’s work, but it was a medium fix for my post-Uzumaki depression.

Jiatsu Circle is also good. It’s about suicide.

Biomeat Nectar is sort of horror-sci-fi, but it’s still scary and violent.

Manhole is a horror that’s not all CRAZY like Ito stuff, but I feel it’s spooky in an intellectual way. It’s a psychological thriller as opposed to horror I guess.

Variante is good too, it’s sort of action/drama but it’s pretty weird compared to my other suggestions.

Arm of Kannon is really good. It’s similar to Ito stuff and is visually and intellectually disturbing.

Also look up stuff by Ono Fuyumi. Fuyumi’s stuff is sometimes themtatically similar to Ito’s a littl bit, but the mangas might be hard to find.

That’s all I can think of right now, but I’llg et back to you if I make any discoveries.
