After successfully solving the mystery surrounding the missing netsuke belonging to Sakuma Katsusaburo, Oko and Seiji are surprised by a well-known local antique art dealer stopping by their shop seeking their assistance. According to the old man, Hamamatsuya Souemon, the paintings on his hanging scrolls are changing each night and he asks that the siblings help get to the bottom of why. With the assistance of the Izumo-ya's tsukumogami the reason for these bizzare occurences is revealed and sometimes fact can truly be stranger than fiction.
