Tsugumomo

A teenage boy discovers a cherished garment that once belonged to his late mother has taken on a life of its own, manifesting as a red-eyed girl determined to help him battle spirits that threaten the living world.

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 problem.

Kazuya's friend Shirou has a tendency to ask girls out without a lot of planning or concern about the outcome; 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.

Sunao's partner 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.
