After seeing Hanamaru and the others' Aqours Challenges, Chika is getting more and more motivated. She stays up late to research μ's in order to make a promo video that people will say they like the most.

Seeing the others succeed in their own challenges one after another, Yoshiko is determined to find her own. She discusses it with her little demons in her usual live stream, but what suggestions do they have for her?

Yoshiko participates in the Numazu Walk Rally in order to get a statue of the Goddess of Fortune. The strength she built up from training gave her a good leg up, but misfortune follows wherever she goes.

The day after Yoshiko successfully completes her Aqours Challenge by obtaining the goddess statue, Aqours receives an unexpected public relations request.

Aqours are appointed as the promotional ambassadors for Izu Mito Sea Paradise. Ruby becomes the leader and works hard to prepare for the event. Then her first day of helping as an ambassador arrives!

Though Aqours had some troubles on their first day as promotional ambassadors, they soon got used to their roles. One day into the second half of the month-long project, you hurry over to see how things are going at Mito Sea.

You decide to check up on Aqours again in Uchiura while they are making progress on their challenges. What do you hear when you begin to interview them more deeply?

Many messages arrive from people who have been following the Aqours Challenges. Among them is a letter from a small group who started a school idol club because of Aqours. What memories does the letter evoke?

After recalling their joint live show with μ's, Aqours grasps the direction of their own promo video. As soon as they put out a request for contributions on the website, they get a ton of responses! What do they all say?

Now that they've picked the song to use for their video and resumed their rigorous training, production is going smoothly for the Aqours promotional video. What happens when it's finally complete?
