Izumoya is a rental shop in the Fukagawa Ward of old Edo, modern day Tokyo, run by siblings, Oko and Seiji. One day, they receive a request from a samurai from a noble family who has lost a precious item that he believes might be a tsukumogami, especially treasured objects that become imbued with spirits. Seiji comes up with a plan to use the shop's resident tsukumogami to help collect information and find the missing item, but when the item is located the case becomes a bit more complicated than expected.
Besides, while it may not 
be the mouse netsuke, Rikyuu,

il netsuke a forma di topo,
Além disso, eles podem não estar
procurando o netsuke de rato,
Да и дело не только в мышке Рикю.
