Uzumaki

Kirie Goshima lives an ordinary life in the coastal town of Kurouzu until her boyfriend Shuichi tells her that the town is “infected by spirals.” His warning sounds absurd, but Shuichi's father has become obsessed with the shape, finding it in shells, whirlpools, and everything around him, and his fixation soon becomes something too horrifying to dismiss as ordinary madness.

Spirals begin appearing in people's bodies, behavior, weather, and even the town itself. Each incident is stranger than the last, while every attempt to escape seems to curve Kirie and Shuichi back toward the same pattern. The spiral is no longer merely a shape, but a force slowly coiling around Kurouzu until its residents can no longer tell which direction leads out.
