It is the day of the Kitasanriku Autumn Festival. There are floats parading around town. Aki and her mother are selling yakisoba at the fair. Also, the crowning of "Miss Kitatetsu" is being held. Shiori (Tourism office secretary) is upset because she showed up wearing a swimsuit but was not informed that the swimsuit category was canceled due to cold weather. Anyway, Yui wins the contest and receives her crown. Aki is happy for her but at the same time, hesitant. Aki realizes Yui is clearly different from her, and unlike herself, Yui is meant to become truly big someday. Haruko reassures Aki that she too, is a hard-working girl who got what she wanted (to be an Ama). She also suggests to quickly make peace with Natsu "or else it will take a long time to make things go back to where they were... Like me." Later, Aki joins Hiroshi in handling the traffic for the parade route because she wants to see Yui up close when her float passes by. Later after the festivities, Aki asks for her autograph and wishes her the best. The next day, Aki asks Natsu once again to reinstate her back to being an ama. Natsu says if she dies in the sea, it would be too much for her to take. Just like what happened to the son of Katsue (Ama, 56 yo) and her ex-husband Rokuro (Fishing Co-op Pres.). Their son got "swallowed up by the waves" 16 years ago when he was trying to retrieve a slipper of a child. The couple tells Natsu not to let the past affect her. Natsu tells Aki, "Don't be foolish as to easily give your life to the sea in exchange for just 500 yen*!" (*the worth of one sea urchin) The Ama leader finally relents but with one condition: "The Ama season will end in one month and so by the end of this month, you have to catch one uni or else you will not become a real Ama!" Aki and the Ama-sans rejoice. At the Tourism Office, Yui's otaku fan, Hibiki comes to offer his pictures and video he had taken of Yui since the ones on the website were "not showing off her charm."
