Hinaki and Juri are hired to be image girls for a Mexican food booth at a world food festival. While helping with the booth's preperations, Hinaki suggests calling in Juri's father, Kamino Serio, to make a special dish using jalapenos, among many other ideas. Later, after giving Kayako suggestions on how to improve her new Premium Dress, Hinaki reflects on how much she has changed in terms of expressing her ideas thanks to meeting the other idols. On the day of the festival, Hinaki's ideas prove to be a great success for the Mexican Booth, which wins the festival.
