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.

Naru and the gang are forbidden by student council president Machi to use the rooftop. But student council vice president and Naru's childhood friend, Tami, promises to buy them time until they can find a new place for their club activities. Hana tries to get traditional Japanese beauty Tami to join the club, but she has to weigh what she wants to do against her position as a Nishimikado daughter.

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.

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!
