In the historical setting of Edo, specifically the Fukagawa ward in old Edo (now Tokyo), a unique practice takes place due to the frequent fires and floods in the area. Instead of buying household items, residents opt to rent essentials like pots, futons, and clothes to facilitate swift escapes during disasters. At Izumoya, a rental shop managed by siblings Obeni and Seiji, a curious collection of items, known as tsukumogami, resides. These objects have transformed into spirits after a century of existence. Occasionally, the duo loans out these sentient possessions to customers. With the ability to perceive and communicate with these spirits, Obeni and Seiji attract other tsukumogami to their shop, drawn by the siblings' reputation.
