Tsukumogami Kashimasu - Season 1

Izumoya is a rental shop in the Fukagawa Ward of old Edo, modern day Tokyo, run by siblings, Okou and Seiji. One day, they receive a request from a samurai from a noble family who has lost a precious item that he believes might be a tsukumogami, especially treasured objects that become imbued with spirits. Seiji comes up with a plan to use the shop's resident tsukumogami to help collect information and find the missing item, but when the item is located the case becomes a bit more complicated than expected.

After successfully solving the mystery surrounding the missing netsuke belonging to Sakuma Katsusaburo, Oko and Seiji are surprised by a well-known local antique art dealer stopping by their shop seeking their assistance. According to the old man, Hamamatsuya Souemon, the paintings on his hanging scrolls are changing each night and he asks that the siblings help get to the bottom of why. With the assistance of the Izumo-ya's tsukumogami the reason for these bizzare occurences is revealed and sometimes fact can truly be stranger than fiction.

Oko has gone to the Hachiya estate to collect various curios from Katsusaburo's fiancée, Sanae; however, Sanae appears to be rather unhappy. Confiding in Oko, Sanae tells her that with the wedding, her mother, Otatsu, recently has become much harder on her in an effort to make her more mature and dignified as befits her status. Seiji and Oko do their best to heal the rift between mother and daughter caused by their misunderstood feelings.

Kounosuke, the young master of the Omi-ya, a kimono shop in the Ryogoku district and who is rumored to be a stylish playboy, has recently been turning up at the Izumo-ya rather frequently. Kounosuke is fairly refined in his manners, but there is a rumor that it might be an act to make women let down their guard, and Seiji is unwilling to have Oko fall for such a person. So one night, Seiji has a certain respected person bring along one of his shop's tsukumogami to a party with Kounosuke to uncover the truth behind this supposed playboy.

Recently, the hot-topic around town has been the appearance of the chivalrous bandit, Itachi Kozo. According to the rumors, the bandit listens to the wishes of those coming to a particular shrine and will grant them. Heizo, a reformed convict now working for the local police, admits to Seiji and Oko that while at the shrine he inadvertently admitted to wanting the princess doll in their shop, and, sure enough, Itachi Kozo appears at the Izumo-ya that night and steals Ohime away. What will be the conclusion of the tale of the chivalrous bandit that has sparked much commotion in Edo?

One morning, Seiji runs into Kounosuke while out on a walk. The two young men discuss recent affairs on Ryogoku bridge, but Kounosuke suddenly loses his balance and falls in the river, accidentally pulling Seiji with him and losing his precious seal box, Kogare-kou, that has been passed down in his family for generations. Kounosuke does his best to look for it, but to no avail. Meanwhile, another young man appears to have found Kogare-kou and demands a considerable sum for its return. With Kounosuke facing being disowned by his family if he cannot get the object back, Seiji and Oko do their best to help him raise the money with the help of the tsukumogami.

Katsusaburo tells Seiji about a young cook from his estate named Tokubei who has recently opened up his own shop, and, as a way to celebrate his success, Katsusaburo hopes to borrow some items from the Izumo-ya to decorate Tokubei's shop. The tsukumogami who are lent to Tokubei's shop, the Tsuru-ya, come back with reports of a mysterious female ghost haunting the property. As the search is on to find out more about the identity of the female ghost, the tragic details of Tokubei's sad past come to light.

One day, Seiji receives an odd request from Kounosuke to look into the background of a seaweed wholesaler named Hansuke that he is on good terms with. Stylish and dashing, Hansuke is a ladies man who has a talent for business despite his age and his seaweed wholesale shop has been very successful, but Kounosuke is suspicious of his unusual generosity towards him believing that Hansuke has ulterior motives. Seiji is unable to find out anything unusual about Hansuke, but while out on a boating trip he notices that Hansuke has an odd reaction to the kiseru that Goi inhabits. What kind of past connection do Goi and Hansuke have?
