Spiral into Horror: Junji Ito

Uzumaki: Spiral into Horror

According to About com:Manga, its story summary is: 

A small seaside town turns upside down when its occupants become mysteriously obsessed with spirals. How can something so small and insignificant become the catalyst for an entire population's descent into insanity? Only Junji Ito, Japan's master of horror manga knows, and he's not telling until you get to the last volume of Uzumaki.

Uzumaki is a series of short horror stories that have one thing in common: the spiral. Each story can stand alone, but also works cumulatively to build suspense as the spiral's grip on the villager's sanity tightens and more people, young and old, succumb to its hypnotic allure.

The spiral incidents, each more bizarre than the last, are narrated by Kirie, a teenage girl who lives and goes to school in Kurozu village. At first, she's skeptical when her childhood friend Shuichi begs her to leave town with him because he senses the evil surrounding them. Later, as the madness claims her classmates, her family members and even herself, she begins to realize to her horror that it may be too late to escape the supernatural spiral snare that is choking the sanity and life out of her hometown.

Tomie: Museum of Terror

Another remarkable work of Junji Ito is "Tomie - Museum of Terror". Tomie is also a three volume series and is continuously-cropped short stories. Its beginning one is his debut volume. Tomie is more grotesque than Uzumaki.

According to Amazon's publish description,  "Tomie" is the story of an eternally youthful and beautiful high school girl, whose admirers are obsessed to the point of murdering her. But to their horror, she is reincarnated over and over.

If you are horror story mania, I bet you would love his manga.
