When spirits cross over into the human world, they can possess old objects and gain a physical form: a 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. Kunato Hyouma is a member of the clan, but is... less than peaceful, since he holds a grudge from when a tsukumogami robbed him of something important. Afraid that Hyouma's brash anger in dealing with these spirits will lead to supernatural catastrophes, Hyouma's grandfather sends him to live in Kyoto with an unusual young woman: Nagatsuki Botan, a girl 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?

Tsukumogami can be dangerous, as Hyoma, a fledgling Saenome, has seen firsthand. After moving in with Botan, a young woman with six tsukumogami caretakers, he has to admit that there may be exceptions - but he’s still on high alert. When he learns of Botan’s true role in the world of tsukumogami, he decides he’ll need to step up in order to protect her. And when Botan’s family sees his true power, they decide he might be just the right person… to marry Botan!

FAMILY MATTERS It’s been two months since Hyoma moved in to the Nagatsuki residence, and he’s starting to feel like part of the family. Sure, there’s a marriage proposal that both he and Botan are trying to ignore, but overall, things have gone smoothly. As Botan begins her third year of university, Hyoma continues his specialized training. That is, until a high-level tsukumogami challenges him to a fight. This tsukumogami knew Hyoma’s siblings—and also knows the paper umbrella tsukumogami who murdered them. And he knows something else, too—a secret that could shatter Hyoma’s peaceful life!

Word of Hyoma’s residence in the Nagatsuki household has spread throughout Kyoto, and the larger tsukumogami groups aren’t happy about it. After all, no one has been allowed to get near Botan for years—human or tsukumogami. When Hyoma goes to pay his respects to a local Saenome clan, they ask him to get rid of Botan and her six tsukumogami once and for all. If Hyoma refuses, he might have an all-out clan war on his hands. His only option is to take on the entire clan by himself!

A vengeful exorcist must cohabit with the spirits he hates in this action-packed supernatural tale that’s now an anime! There are powerful beings whose spirits dwell within old objects: tsukumogami. Hyoma is a young man who despises these evil spirits for robbing him of something precious. His mission: to use the supernatural powers granted to him to dispatch these tsukomogami back to their own world, no matter what it takes. But when Hyoma’s grandfather sends him to live with Botan, a kind-hearted girl who peacefully shares a house with an assortment of overprotective tsukumogami, it’s more than Hyoma can bear. Can Botan help Hyoma overcome his rage, or will his thirst for vengeance lead him down a dark and violent path? The supernatural battle action fantasy manga that inspired the anime!
