Event Year: 2013

As the Tamaya shop decides to put on a mochi pounding event for October 10, Mochi Day, Anko asks Tamako to set some daifuku aside for Yuzuki, the boy she has a crush on, but can't bring herself to face him in person. Asked by Tamako to help, Mochizō learns that Anko is depressed because Yuzuki is transferring to another school on Mochi Day. As Mochi Day arrives, Tamako gives Anko the encouragement to see Yuzuki off before he leaves. Receiving some fresh mochi Tamako gave Anko, Yuzuki tells her that they'll see each other again when his family next comes to Tamaya for some mochi. Meanwhile, Tamako comes across Mamedai playing a familiar song from her childhood. The record store owner, Kunio Yaobi, tells Tamako and the others that the song was written by Mamedai for her late mother, Hinako.

Deciding his obesity needs to be addressed, Tamako, Choi and the others decide to put Dera on a mochi-free diet until he loses enough weight to fit into a birdhouse Kanna made. In order to keep watch over Dera to make sure noone feeds him, Choi goes to school with Tamako and the others, where she joins in on classes and helps Dera get some much needed exercise, before going to a used clothes store. As Dera shows up the next day with a curiously slim body, Kanna and Midori give Choi a sweater they made for her.

Choi Mochimazzi, a fortune teller from Dera's homeland, comes to stay at Tamako's house, revealing that both she and Dera come from the island's royal family. When Choi becomes annoyed by Dera gaining weight and forgetting his mission to find a bride for the island's prince, he claims he is being held against his will, leading her to be distrustful of the good will Tamako and the shopkeepers show towards her. As Choi tells fortunes as a mean's of paying back everyone's kindness, shopkeeper Sayuri Yumoto reveals she is getting married, much to the dismay of tofu shop owner Tomio Shimizu, who had a crush on her. This leads Choi to think about her own unrequited feelings for the prince, leading to her getting a fever after passing out in the bath. After Tamako helps her overcome some of her homesickness, she becomes a bit more accepting of everyone's kindness.

Noting that not too many people come by the market during hot days, Tamako suggests they put on a haunted house to help cool people down. As Tamako, Midori and Kanna work on preparing the haunted house, Mamedai claims he saw some ghosts floating about at night, leading the shopkeepers to become paranoid, believing the market to be cursed. After a test run by Shirori and Dera, the haunted house starts gaining some attention whilst Shiori helps clear up some of the 'hauntings' the shopkeepers have been experiencing. The haunted house proves to be a huge success, drawing lots of customers to the market. At the wrap-up party, Kanna reveals she and Dera were behind the ghost sightings from before. As Dera falls over in shock, his eyes once again project a video from the foreign prince, informing everyone that someone named Choi is coming to the market.
