Tsugumomo

Kazuya Kagami wakes up in class from a bad dream to discover that he is inadvertently groping classmate Chisato Chikaishi's breasts. After escaping her wrath, Kazuya goes to the roof where he takes comfort in his mother's obi. Kazuya is attacked by a possessed wig and falls off the building, but is saved by his obi. From within the obi, a young girl, a tsukumogami, emerges. They are met by the host of the wig. The tsukumogami asks the host to sever their link with the wig, which the tsukumogami calls an amasogi or curse. However, the host and wig attack and the tsukumogami is forced to destroy the wig before disappearing. At home, Kazuya reflects on the day's events before falling asleep. After another nightmare, he wakes to find the tsukumogami in his bed. After avoiding a confrontation with Kazuya's possessive sister, the tsukumogami introduces herself as Kiriha and that she the tsukumogami of Kazuya's obi and that Kazuya is now her servant.

Kazuya and class rep Chisato find themselves trapped in the school library, and it's up to Kiriha's knowledge of spirits and the forms they take to get them out.

A towering priestess shows up looking for Kazuya, and the person who sent her has an offer he and Kiriha might not be able to refuse.

Kiriha is being battered by the water goddess Kukuri-hime's attacks, when a mysterious vision gives Kazuya advice on how he and the tsugumomo might manage to survive.

Now that Kazuya has accepted the duty of exorcising any supernatural trouble that crops up, it's up to Kiriha to whip him into shape.

When the entire school starts acting like characters from a dating sim, Kazuya and Kiriha are forced to find the amasogi responsible before the affected people do something they'll regret.

Thanks to his unique condition that causes him to attract supernatural trouble, Kagami Kazuya acts as an exorcist with the help of his partner, the fully incarnated spirit of an obi sash, Kiriha. Realizing that Kazuya's status as a literal trouble magnet could be more than the two of them can handle, the monster hunting duo decides to start a consultation group with the help of their classmates, so that they can subtly keep an eye out for any trouble at their school.

Kazuya and Kiriha had previously won a duel against the hot-headed tsukumogami-wielding Sunao. After her defeat, the young swordswoman takes the lessons she was taught by the duo to heart, and now turns to Kazuya for some help with a parental problem...

Kazuya's friend Shirou has a tendency to ask girls out without a lot of planning or concern about the outcome. Just when it seems like that approach has finally managed to endear himself to a girl, the looming threat of an amasogi puts a damper on any potential romance.

Thanks to her unique condition that causes her to attract supernatural trouble, Kagami Kazumi acts as an exorcist with the help of her partner, the fully incarnated spirit of an obi sash, Kirio... wait, what?!

Sunao's partner, the katana tsukumogami Kotetsu, has still not woken up. With things looking desperate, the young swordswoman turns to Kazuya and Kiriha for help in attempting to save her partner's life.

A mysterious group of students has been causing amasogi to appear in town. But where did they come from, and what are they after?
