I Won't Cry, I Won't Cry.Thanks to Pastel Palettes guitarist and Haneoka High student council president Hina Hikawa, her school and Hanasakigawa prepare for a joint cultural festival. Hina also forms a band of students from both schools (made up of Aya, Afterglow's Moca Aoba and Tsugumi Hazawa, Roselia's Lisa Imai, and Hello, Happy World!'s Kanon Matsubara) to perform at the festival. Poppin'Party prepares for their performances at both the cultural festival and their live show, with Tae choosing to gain additional experience with impromptu street performances. During one session, she reunites with her childhood friend Rei Wakana (LAYER). Rei recalls the two promising to form a band together and brings up the idea, to which Tae hesitates.
