A sleepy coastal town is at the center of something terrible. It begins innocuously, with the spirals in rivers, plants, seashells. Then it progresses. These spirals become more prevalent, appearing on people’s bodies, taking hold of their minds, and driving them to kill others, and themselves. It becomes apparent that the spirals are part of something larger, and no one in the town is safe from this phenomenon.
The protagonists are high-schoolers, Kirie and her boyfriend Shuichi. The stories are told from their point of view, but the story is much larger than either of them. The author manages to tell the story of the whole town and works a multitude of unique characters into the novel. What makes this collection truly scary is the art. The often vicious actions of the townsfolk are made real by the equally monstrous illustrations provided by Ito. This collection fits squarely into the genre of body horror, so squeamish readers should be wary.
