Top 17 Dementia manga you should read right now. [2025 List]

17. Uzumaki

Kurozu-cho, a small fogbound town on the coast of Japan, is cursed. According to Shuichi Saito, the withdrawn boyfriend of teenager Kirie Goshima, their town is haunted not by a person or being but by a pattern: uzumaki, the spiral, the hypnotic secret shape of the world. It manifests itself in small ways: seashells, ferns, whirlpools in water, whirlwinds in air. And in large ways: the spiral marks on people's bodies, the insane obsessions of Shuichi's father, the voice from the cochlea in your inner ear. As the madness spreads, the inhabitants of Kurouzu-cho are pulled ever deeper, as if into a whirlpool from which there is no return...
