Keke Tang introduces Kanon Shibuya to Sunny Passion, describing Yuna and Mao as the "Sun" and "Sexy Night" of SunnyPa respectively. She has a giant poster of them at home and shows Kanon a video of them dancing to HOT PASSION!!. Sunny Passion is shown stretching before the competition, and watches KeKa's performance. In Episode 5, Sunny Passion visits Kanon Shibuya's cafe. They introduce themselves, and explain that they hold a concert in their hometown of Kozu-shima every summer and want to invite Kanon Shibuya, Keke Tang, and Sumire Heanna as guests. They accept, and then practice together. Sunny Passion asks Kanon and the others about their training regimen, wondering how they were able to put on such an impressive performance as newcomers. Kanon shows them their regimen, and mentions that Chisato came up with it.

After practice, Chisato meets with Sunny Passion privately to ask if the three girls can win the competition. Sunny Passion says that although they're great at singing, it would be difficult for them to win because they rely too much on Chisato. They explain that their dancing lacks enthusiasm and individuality, and that they won't be able to move forward on their own if they continue like this.

Later in the episode, Kanon, Keke, and Sumire arrive at {{w|Kōzu-shima}}. They do many fun things with Sunny Passion, such as diving at Akasaki Promenade, eating passion fruit ice cream, and bathing in the hot springs while stargazing.
