The movie remembers that these girls matter more than the songs. Every character gets a moment that feels earned, a small choice or confession that explains who they actually are when the spotlight isn't on them. It's a film that knows the difference between a concert and a story, and it never confuses the two.
The Nijigasaki idols face their biggest challenge yet when they compete in the School Idol GPX, a prestigious nationwide competition held in Okinawa. Ayumu, Kasumi, Shizuku, Kanata, Emma, and Lanzhu must navigate intense performances, new rivals, and the pressure of representing their school on a national stage. As they prepare for the tournament, each member confronts what it means to push themselves to their limits while staying true to their bond as a group. The competition tests not just their vocal and dance abilities, but their commitment to each other and their dreams. Surrounded by talented idols from across the country, the group discovers that winning isn't just about technical perfection, but about connecting with audiences and finding their unique voice as performers. This first film sets the stage for an emotional and high-stakes journey that will reshape what these girls understand about friendship, ambition, and what it takes to shine on the biggest stage.
