Wanting to get her own Grade Up Glitter to catch up with the others, Ako searches for a venue for her own performance. With all other options fully booked, Ako manages to book a stage on the roof of a department store. However, she becomes conflicted when Tsubasa invites her to appear on her show at the same time as her performance. Ako becomes tempted to go with Tsubasa in order to better guarantee a Grade Up Glitter, but when she sees how hard some her young fans are supporting her, Ako ultimately decides to keep her promise to perform at the department store for the children. Despite not getting the Grade Up Glitter as a result, Ako is praised for her decision by Yume, Kanata, and Subaru.
