Two adopted siblings operate a rental shop in old Edo (modern-day Tokyo), an area prone to fires and floods. They rent out everyday items so that residents are not hindered when fleeing. Among the inventory are ancient objects that have become spirits after centuries of existence, known as Tsukumogami. These supernatural beings eavesdrop on conversations around town and spread them as gossip. The kind-hearted siblings must respond to these disputes and resolve the situations by utilizing the powers of the Tsukumogami.
