In Episode 3, it's revealed that KeKa will be competing against Sunny Passion in the Yoyogi School Idol Festival. 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. In Episode 6, Sunny Passion wakes up Kanon and the others bright and early to practice for their concert. However, Keke runs out of energy as soon as they begin running, leading Yuna and Mao to suspect she ran out of energy during the fun they had the previous day. Fortunately, a performance from Sunny Passion is enough to bring her back to a full recovery.

Sunny Passion then shows the others their work-in-progress stage. They explain that since there aren't enough people living on the island, they had everyone at their school help build it, and that the fact they're doing something for the island they love is what drives them forward.

Afterwards, Yuna notices Kanon coming up with lyrics. Kanon talks to Yuna about what she said earlier about helping the island, and how it inspired her when writing lyrics. Yuna asks if Kanon is also pursuing being an idol to help her school, and she responds saying their school actually opposes school idols. Yuna assures Kanon that you don't need a specific reason to be a school idol, and that there are many people who are idols simply because they love singing. Kanon also tells Yuna about Chisato and her lifelong passion for dancing, which leads Yuna to tell her she wonders whether that's a valid reason to not be a part of the group.

Later on, Yuna and Mao eat the delicious meal Sumire and Keke made together. In reality, Sumire did all the cooking, which leads Keke and Sumire to begin arguing, which Mao sees as them being close friends. During the evening, all five girls look at the moon together. Kanon then receives a call from Chisato, and afterwards asks Yuna for a favor. The next day, Yuna and Mao show the girls the completed stage, and later that night it's finally time for the concert. After Sunny Passion performs, Kanon and the others are revealed as guests, and it turns out the favor Kanon asked for was to have Chisato perform with them as well. In Episode 9, Kanon does a video call with Sunny Passion about coming up with a group name. Yuna and Mao reveal that a fan came up with their name, and that they weren't nearly as popular back then as they are now. They mention that to make themselves more recognizable, they often put up videos. ("Song for All") In Episode 12, Sunny Passion stops by Kanon's house since they were in town to shop for the Tokyo tournament. They congratulate Liella on their hard work preparing for the tournament, but declare that they're the ones who are going to win the tournament, to which Kanon responds saying Liella also intends to win. Kanon then talks to them about what it means to win, and says she doesn't know how to feel about competing when it comes to singing. Yuna and Mao say that although singing is something you can enjoy by yourself, competing in competitions like Love Live helps school idols become even better, and that Kanon will understand why everyone wants to win once they sing at Love Live.
