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.
While it is, indeed, difficult 
to use a full moon hanging scroll,
،مع أنّه من الصّعب استعمال لفيفة بدر معلّقة
Es stimmt schon, dass eine
Vollmond-Wandrolle selten eingesetzt wird.
Aunque es ciertamente difícil
usar un pergamino de una luna llena,
Aunque es ciertamente difícil
usar un pergamino de una luna llena,
Sebbene sia difficile trovare un'occasione
 adatta per usare un kakejiku con una luna piena,
De fato, é difícil usar um kakejiku de lua cheia,
Соглашусь, свиток 
с полной луной не везде повесишь,
