When spirits cross into the human world, they can possess old objects and gain physical form: becoming tsukumogami. Tsukumogami can be gentle, violent, or somewhere in between, so the Saenome clan peacefully helps send them back to the spirit world to avoid destruction. Hyouma Kunato is a member of the clan, but is... less than peaceful, as he holds a grudge from when a tsukumogami robbed him of something important. Fearing that Hyouma's brash anger in dealing with these spirits will lead to supernatural catastrophes, his grandfather sends him to live in Kyoto with Nagatsuki Botan, an unusual young woman who actually lives with tsukumogami like family! Can Hyouma learn to control his emotions when dealing with tsukumogami, or is his own spirit doomed to be possessed with rage forever?
