You've come to Numazu to look into Aqours' secret. However, since you've come on a whim, you realize you don't know where to go to meet them. For now, you just decide to go to their school, Uranohoshi Girls' High School.

You've come to Numazu with no plan. Even after asking around the school, no one seems to know where Aqours is, so you're running out of steam. You follow some advice that since you've come this far, you should go see the ocean.

You find Riko at the beach, and after telling her you came all this way to find out Aqours' secret, she kindly brings you to Chika's place. Another Aqours member, You, is there and they had been discussing the Summer Festival.

You ask Chika and You about the secret to Aqours' performance. It turns out they're looking for the same thing you are, so you think about why everyone shines. The next day, Chika brings you to meet Mari, Dia, and Kanan.

After speaking with Mari, you decide to help out in the Summer Festival. Next, you go visit the freshmen who are busy with preparations. You hear the cheerful voices of the three of them in the room, when…

Just like Chika and the others, the three girls you meet, Yoshiko, Ruby, and Hanamaru are seeking their own way to shine. Aqours has members peculiar enough to rival even Nijigasaki. That night, they hold a welcome party for you.

Aqours seemed out of your league, but you see they love school idols, too. You beg them to let you help with the festival. The next morning, as you walk along the ocean road, you run into Mari and Kanan out for an early workout.

You're exhausted from training with Mari and Kanan. Aqours is the real deal. You head to the kitchen to help You and Yoshiko with making samples of food for the festival, when suddenly you hear a terrible scream from inside!

You feel relieved after Yoshiko's menu suggestions become a bit more normal. You help Ruby and Hanamaru with the Numazu tourism guide next. Hanamaru's vast knowledge really throws you for a spin.

Ruby and Hanamaru's tourism guide is polished up and truly shows the appeal of Numazu. You watch their dance lesson, and during a break you find Dia intently writing something in a notebook. What could it be?
