Tsugumomo

Kagami Kazuya is an ordinary school boy who has one slightly odd habit: he carries around the obi of a kimono that belonged to his late mother. This wouldn't be a big deal, until the obi reveals itself to be a tsukumogami!

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.

Kukuri and Kokuyou have nowhere to live, and almost no income. Kiriha forces Kukuri to visit a neighboring local god for a loan, but the collateral being demanded might cost the two of them much more than just money.

Kazuya takes Kiriha and Kukuri grocery shopping, and then Shirou finds his charisma boosted to uncontrollable levels by a cologne.

A mysterious phantom student is stalking Kazuya's school, and Kiriha says that there's no such thing as ghosts. That leaves only one explanation: another amasogi.

A malison cleanser who knew Kazuya's mother is unimpressed with his skills, and wants to strip of him of his duties. But after seeing how malison atonement impacts the people struck by it, does Kazuya even want to put up a fight?

The duel between Sunao and Kazuya begins. Can Kazuya and Kiriha manage to overcome Sunao's thirst for vengeance?

Kazuya's duel with Sunao ends with Kiriha and Kazuya dead set on proving that a tsugumomo will be stronger when its master treats it as a partner rather than just a tool.
