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!
