Titre original : I Like Senpai!
Phone calls keep pouring in, inquiring about Aki. News has spread that Yui and Aki will be doing a collaboration. Yui is not pleased because they were not even consulted to begin with. But Aki says she's okay with it. Yui tries to dissuade her since she knows Aki is not used to such things that Yui is doing (dressing up in "cosplay," being bombarded by cameras). Daikichi says not to worry because they will be standing guard and even suggests that Yui could help Aki out by "dressing up as an Ama and sell unidonburi". Without realizing it, he mentions the word "rivals" and somehow Yui suddenly changes her mind and agrees to do it. (Apparently, it's a sign that she hates to lose). Next morning, Aki and Yui do what they're told to do. The ride is jam-packed with happy passengers, taking their pictures and buying unidonburi while Daikichi and Yoshida are just over the moon. Back at the Amano home, Natsu and the rest frantically churn out more unidonburi to sell but are running out of uni. Rokuro tells them that more kilos of uni will be arriving from another village. Haruko wakes up to the ruckus and is surprised to learn about the collaboration. That night everyone is celebrating the fact that for the month of September, the KitaTetsu has finally earned a profit. "I don't even remember if this ever happened before!" an emotional Daikichi exclaims. But Haruko is not rejoicing. She tells Daikichi she will not allow Aki to do what she did that morning. "It's unsightly, turning my daughter into a spectacle." But Natsu defends the decision, saying there is nothing wrong with it. "The Ama tourism IS a service industry. It's a long cherished dream to have more customers." Haruko asks Aki if she's really okay with it. "Is this what you stayed here for?" Aki replies, "If I'm helping everyone, then I'm fine with it." However, when going home, Aki looks pensive, seemingly doubtful of her own response. Back at the bar, Sugawara and Daikichi talk about how their perception about otakus have changed. They were initially prejudiced against them but now they find them to be gentle, well-mannered, and earnest people (One even drew a fanart/manga of Yui and Aki). Daikichi says he knows he may be asking too much from the two girls but "such an opportunity may never happen again." And he thanks Haruko again for making it possible. The next morning, Aki has not arrived at the station yet for their "collaboration." So Yui goes to the Amano house to fetch her. Aki tells her she's different from Yui, after all. She's just an ordinary schoolgirl, who's not confident about her looks and feels awkward to be in such a spotlight. "All I wanna do is to dive." Yui tells her she is not ordinary, and that people came from faraway places to see her. "Regardless of looks or pleasing people, isn't enough that it's cool?" Yui's pep talk helps and both finally go to the train station to sell unidonburi. Next day in school, Yui pulls Aki along to a building where there are small circular glass windows. Aki peers inside and is astonished to find a man deep inside a pool, wearing a heavy diving suit and helmet. He looks like an astronaut. "What is this~?!"
