When a spirit moves from the spiritual realm into our world and takes possession of an object, it becomes known as a Tsukumogami. These spirits can manifest in various forms, ranging from benevolent to malicious. The Saenome clan is responsible for returning these spirits to their own dimension to prevent harm. Hyouma Kunato, a member of the clan, has difficulty controlling his emotions when dealing with these spiritual entities due to a past grievance. To help him learn self-control and avoid causing supernatural disasters, his grandfather sends him to live in Kyoto with Nagatsuki Botan, who lives alongside Tsukumogami as if they were family members. Can Hyouma overcome his anger issues and find peace, or will he forever be haunted by his own rage?
