Bringing Poppin'Party and RAS together at Galaxy, Marina announces that both bands will proceed to the finals at the Budokan, to everyone's relief and excitement. Each band then prepares to perform in the Budokan which includes a dress rehearsal at CiRCLE. Along the way, Poppin'Party prepares a new song that they want to play with Roselia and RAS, both of whom accept. Meanwhile, Asuka volunteers to help in the Girls Band Challenge, including creating a poster for the finals and interviewing the bands for her blog. The night before the finals, Kasumi sees Asuka proofreading her blog post. Asked to explain how she finds sparkling, heart-pounding moments in her life, Kasumi recounts how she found these moments by forming Poppin'Party and meeting and making new friends over the past year.
