Kasumi Toyama and the other members of Poppin'Party—their high‑school ensemble—have entered their second year. With the new term, fresh hurdles appear: student council responsibilities, cram‑school classes, part‑time gigs and more. They juggle assignments and auditions. Additionally, they are now split across different homerooms, cutting into the time they can spend together. In hindsight, those carefree moments feel like a distant dream now that members are too busy to even meet in Arisa Ichigaya"s basement for rehearsals. While the group wrestles with this reality, an unfamiliar girl steps forward, inadvertently thrusting them back into the limelight. She brings fresh energy that rekindles their passion.
During this surge of all‑female groups, Afterglow, Pastel*Palettes, Roselia and Hello, Happy World! also emerge. Each band, made up of distinct personalities, lights up the stage with their performances. Their rivals sharpen their craft, fueling friendly competition. As Poppin'Party reenters the music world and meets new companions, that glittering, pulse‑quickening sound begins to play again. Together they set the stage ablaze once more.
