Siblings Minato and Akira Lee have moved to a new town, and they're expecting things to be different— but not this different! Ghostly figures tower over and pass through buildings, drawing no reaction from the locals, some of whom appear far from normal themselves. When Akira spots a strange creature outside her window, she and her new friends organize a search. If no one else can explain the uncanny appearances, the investigation club will get to the bottom of it!
