Episode 1 Summary: Siblings Okou and Seiji manage a rental shop in Edo called Izumonya. While their bread and butter is based around renting everyday objects to customers, they also hold onto an inventory of tsukumogami, well-loved items that have gone on to develop souls. Though they try to keep a lid on this strange specialty, word tends to get around; they’re called upon by a man about to marry into a wealthy family who’s lost a particular family heirloom. The mouse netsuke (charm) that’s gone missing is said to have sprouted legs and run away, and while the siblings are coy about the possibility of it being a tsukumogami (or even acknowledging that tsukumogami are real), they soon employ their own tsukumogami to gather information about the situation. What are eventually discovered are some half-truths about the impending marriage, as well as some fuller truths about the groom’s relationship with his older brother. There might also be some complicated feelings between Seiji and Okou, who aren’t related by blood.
