After seeing the detail with which Dia records Aqours' activities, you decide you want to do the same for Nijigasaki. You spend your time productively, and before you know it the festival is only a week away.

You take on secretarial duties for the Summer Festival, but something about Chika's behavior that day catches you off guard. Then you run into Riko, who just so happened to sense the same thing.

Chika returns to normal after being able to crank out the new lyrics she had been worried about. The festival is tomorrow, and the tension in the air is electric.

The night before the festival, you have fun sharing secrets with Chika who has snuck to your room. You start to feel “that special something” so important to school idols. Now, it's the big day, but Numazu's skies are very dark.

The first day of the festival is canceled by a typhoon. Still keeping hope for the next day, you and Aqours make ten teru teru bozu dolls. Will your prayers get through?

It's the second day of the festival, and although the sun shines, the storm has scattered branches and garbage all over town, so the Festival Committee has decided to cancel today as well.

Chika won't give up on the festival, and everyone in Aqours feels the same. Will the last-ditch effort to clean the town really work?!

Mari convinces the Festival Committee to retract the cancellation! Thanks to your announcement on the town P.A., locals and even tourists help Aqours with town cleanup.

The festival turns out to be a huge success. Aqours overcomes hardship and puts on a wonderful show for everyone. At the after party with the still-excited members, you ask Chika about something she said the first day you met her.

In the end, it seems that yet again they didn't find their shine like Chika had talked about. It is only you that may have barely grasped what it is, and with that you leave Numazu.
