Naru and Hana discuss how they can get their school interested in yosakoi. Their classmate Yaya isn't too happy about Naru and Hana becoming so close. A little mistake becomes the beginning of a fight between Naru and Yaya, but...

Naru and Hana visit yosakoi shop Masaru, where they learn of the summer Hanairo Yosakoi Festival. Hana is eager to participate through their Yosakoi Club, but to form a club, they need at least four members. As Hana performs all around the school to recruit members, Yaya asks her how she could be so happy.

With Tami and Yaya having joined, the club finally has four members, and they begin working towards their goal of performing in the Hanairo Yosakoi Festival in the summer. But Naru and the others have never seen real yosakoi, so by Tami's suggestion, they go to the Shounan Yosakoi Festival.

With the department store event coming up, Yaya seems somehow depressed. It seems to have something to do with her band's audition. Yaya is reluctant to talk about it, and when Naru and the gang try to help her out, she accidentally explodes at them.

With Machi having joined the Yuihama Academy Middle School Yosakoi Club, the group plan a training camp for the Hanairo Yosakoi Festival at a hot spring in Hakone. Machi is under pressure to catch up with the rest of the club.

Just three weeks until Hanairo Yosakoi Festival! Everyone is hard at work practicing, but Hana seems a bit down. One night, after recording the vocals for their song, Hana visits Naru, and tells her...

The Hanairo Yosakoi Festival is finally here. It was Naru that gave everyone encouragement after Hannah's departure. Naru visits the place where she first met Hana. And once again, Hana runs through the town hoping to dance with everyone again. The girls have a new summer memory. Cute and energetic, HaNaYaMaTa!
