Kirie Goshima lives with her family in the small town of Kurouzo-chou. Her life is uneventful until, one day, strange events begin to accumulate. At first, they are just shells arranged in a certain pattern, as well as eddies in the water and the air. According to Shuuichi Saitou, Kirie’s friend, they are all connected to a phenomenon that haunts her hometown: Uzumaki, the secret form that can change the entire world. Soon, people begin to behave strangely, too, as the spiral forms are increasingly found on their bodies as well. Before they can prevent it, the entire city threatens to sink into chaos and madness, caught in a vortex from which there is no escape.
