Uzumaki by Junji Ito
From a gentle contemporary comic to the most disturbing panels you’ll ever lay your eyes on, I think this gives you an idea of how much variety there is within manga and manhwa. Junji Ito’s name is synonymous with horror manga, so if you’re looking for a Halloween manga read, you really can’t go wrong picking up any of his books. Uzumaki is his most popular, and it’s about a town haunted by a spiral pattern. If that doesn’t sound scary to you, believe me, you will change your mind after reading this.
