Kunato Hyoma, who harbors a hatred for tsukumogami, is forced to live with a house full of them and their enigmatic mistress, Nagatsuki Botan.

A bad first impression threatens to get Hyoma kicked out of his new home after only three days if he can't win over his tsukumogami hosts.

Hyoma has one more tsukumogami's support to earn before he'll be allowed to stay in the Nagatsuki household... but Yu seems completely unyielding.

Having earned his right to remain in the Nagatsuki residence for a year, Hyoma learns about the ulterior motive behind his stay.

Hyoma visits the Saenome of Kyoto, the Kadomori Clan, to get permission to act on their territory. But the Kadomoris have their own intentions...

The battle with Kai reveals secrets that the Nagatsukis would rather leave unknown.
