Momo Ayase and her classmate Ken Takakura, nicknamed Okarun, could hardly disagree more about the supernatural. Momo comes from a family of spirit mediums and believes in ghosts but dismisses aliens, while occult-obsessed Okarun is convinced aliens exist and refuses to believe in ghosts. Their argument leads them to test each other's claims: Momo visits an abandoned hospital associated with UFO sightings, while Okarun enters a supposedly haunted tunnel.

Both quickly discover that the other may have had a point. Their separate encounters with frightening paranormal forces draw them into a much stranger world than either expected. As Momo awakens a hidden power and Okarun becomes empowered by a curse, the pair must face new dangers together while their combative friendship begins developing into something more.
