You could try 'Parasyte'. It has a horror element and keeps you on the edge of your seat. The story and art style are quite engaging and similar to the kind of horror in Ibitsu. Also, 'Uzumaki' is another great option. It has a unique and disturbing horror concept that might appeal to you if you like Ibitsu.
I'd recommend 'Tomie'. It has a similar creepy and mysterious vibe as Ibitsu, with lots of twists and turns.
Well, 'Junji Ito's Collection' is worth checking out. It has various horror stories with similar levels of intensity and strangeness as Ibitsu. The art is really creepy and adds to the horror factor. Another one is 'Gyo', which has some terrifying and unusual elements that might remind you of Ibitsu.
