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.
To be frank, the pictures on some 
of my hanging scrolls change at night.
في الحقيقة، تتغيّر الرّسومات على 
.بعض لفائفي المعلّقة في اللّيل
Ich sag es frank und frei. Meine Wandrollen
wechseln jede Nacht ihre Motive.
Si les digo la verdad, las imágenes
de mis pergaminos cambian cada día.
Si os digo la verdad, las imágenes
de mis pergaminos cambian cada día.
Les dessins de mes rouleaux suspendus
changent chaque nuit.
Sarò diretto, le immagini rappresentate
 in alcuni miei kakejiku cambiano durante la notte.
Sendo direto, meus kakejikus 
 mudam de imagem à noite.
Дело такое: картина на одном 
из моих какэмоно ночью меняется.
