In a dual A-side single showdown where the members are split into two teams, Nana and Yume are set to challenge popular members like Ruri. It's a battle they can't afford to lose if they want to rise within the group, but Nana's side includes the resting Yukino and the unmotivated Mayo, making the song complicated. Overwhelmed by the skills of the opposing team, Yume loses her confidence. Seeing this, Nana takes a certain action... And thus, they face the main event of the MV shoot that will determine the outcome!
