It is the first day of school for Rinku Aimoto, who had recently moved back to Japan after living abroad in Africa. During lunch, she overhears a familiar song over the intercom that she traces to DJ and broadcaster Maho Akashi. Rinku expresses interest in how DJing works, prompting Maho to take her to a performance by Peaky P-Key that inspires her to start her own unit.

Maho teaches Rinku about song transitions, but Rinku's enthusiasm prompts Maho to suggest that Rinku should be the group's dancer. The two then put up a promotional poster that fails to generate interest until Maho learns about a remix contest.

Muni Ohnaruto attends Maho and Rinku's concert, which evokes memories of being childhood friends with the latter. Although her initial attempts to talk to Rinku fail, she encounters her and Maho at a café and intervenes when she disapproves of Maho's proposed promotional poster.

Looking for more ways to gain popularity ahead of the school festival's Sunset Stage competition, the group enters a songwriting contest organized by Photon Maiden. Rinku volunteers to learn the piano to create a melody for the song, and she catches the attention of Rei Togetsu, a pianist who regularly practices in the school's music room.

Although the group continues to grow in popularity, Muni is peeved about receiving no attention beyond her VJ title and wants to increase her presence by singing an image song. Unsure of how to compose the ideal song, Rei visits Muni's house for a sleepover.

Finals are on the horizon so Happy Around plan a study session at Rei's house.

Happy Around wants to perform on Christmas Day, but Maho is unable to schedule a concert on that day. While Rinku mopes by eating, she meets Kyoko Yamate, the leader of Peaky P-Key. Kyoko, who had been watching Happy Around, invites her to attend Peaky P-Key's upcoming Christmas live.

Maho fears Rinku is being recruited to join Peaky P-Key, and her worries are exacerbated by misunderstandings of conversations between the group and Rinku, particularly the latter maintaining a secret with Kyoko.

Happy Around reaches eighth place in the Sunset Stage rankings to qualify for the competition, but their position is jeopardized by the rise of Photon Maiden. After Photon Maiden's latest performance, the two groups are tied and are subject to a one-on-one battle to break the tie.

Rinku walks in on Rei singing her song and encourages her to perform it at the Battle Mix Party. While Rei is initially hesitant as she fears the song does not match the unit's image, she agrees upon receiving the others' blessings.

While listening to Happy Around's song, Saki senses a new, calmer color in Photon Maiden's music rather than the usual bright hues.

Rinku suggests performing a rap battle with Muni at the Sunset Stage.

Happy Around is pitted against Peaky P-Key at the Sunset Stage.
