Saenome are charged with containing spirits that inhabit objects and pose a threat to society. While these spirits, known as tsukumogami, are typically docile and resolved through dialogue, Hyouma Kunato, scarred by a past encounter, opts for aggressive tactics. Concerned about Hyouma's methods, his grandfather Zouhei insists he reside with Botan Nagatsuki, whose family comprises six tsukumogami, to learn a more peaceful approach or risk expulsion. Reluctantly, Hyouma agrees as he seeks vengeance for his losses. As malevolent spirits stir unrest, Hyouma must reconcile with his animosity towards Botan's enigmatic kin and earn their trust to combat the growing threat.
