I heard a lot about him and his works and I was always fascinated by his drawings but there are a lot of collection of his short stories (I don’t know if it’s the proper way to call them but you got the point) so I was wandering which was the best one for someone who never read anything about him
If you’ve ever seen that “This is my hole” meme, the story Enigma of Amigata Fault is where that originated from. A personal favorite of mine is Long Dream. And a longer series of overarching stories called Uzumaki is great as well.
he has a bunch of shorter stories that you could easily jump into without any order but i’d recommend reading uzumaki first. its a classic, is one of his longer mangas, and encapsulates a lot of what makes ito’s stories unsettling. i’ve never actually gotten one of the short story collections so i can’t recommend any in particular, but i’ve yet to read an ito manga i regretted reading so i would say just pick whichever one interests you the most.
also, if you’re into cosmic horror, i recommend hellstar remina since i don’t see it talked about as often as his other stories.
