At the Budokan, the annual Tsukino Concert showcases the top idol units of Tsukino Entertainment Production. The leaders of the groups SolidS, SOARA, QUELL, and Growth must create four distinct songs for their respective units to perform on the festival's second day. For SolidS leader Shiki Takamura, composing four new songs is a difficult task as he struggles to find inspiration. Sora Oohara must overcome past mistakes to propel his unit, SOARA, to the top. Shuu Izumi, wishing to escape his past stardom, is determined to raise his unit, QUELL, to the popularity level of his previous group. Growth collaborates with rival group ZIX prior to their debut, a move leader Kouki Etou is reluctant to make. Tsukipro The Animation follows the stories of these four units simultaneously as they navigate their daily lives while preparing for the Tsukino Concert.
