In the town of Kurouzu-cho, Kirie Goshima lives a fairly normal life with her family. As she walks to the train station one day to meet her boyfriend, Shuuichi Saito, she sees his father staring at a snail shell in an alley. Thinking nothing of it, she mentions the incident to Shuuichi, who says that his father has been acting weird lately. Shuuichi reveals his rising desire to leave the town with Kirie, saying that the town is infected with spirals. But his father's obsession with the shape soon proves deadly, beginning a chain of horrific and unexplainable events that causes the residents of Kurouzu-cho to spiral into madness.

After being aggressively rejected, Momo Ayase finds herself sulking when she stumbles across a boy being bullied. Saved by her rash kindness, the alien-obsessed boy attempts to speak to her about extraterrestrial interests he believes they share. Rejecting his claims, Ayase proclaimed that she instead is a believer in ghosts, starting an argument between the two over which is real. In a bet to determine who is correct, the two decide to separately visit locations associated with both the extraterrestrial and the supernatural—Ayase visiting the former and the boy visiting the latter. When the two reach their respective places, it turns out that neither was wrong and that both aliens and ghosts do exist. This marks the beginning of Ayase and the boy's adventure, as they attempt to fix the surreal, supernatural, and extraterrestrial elements around them to return to a normal life.
