A girl discovers a power that lets her meet every idol who ever mattered in this universe, and the show spends 25 episodes actually earning the weight of that gift. The production knows exactly what it's doing: this is a love letter to everyone who watched Aikatsu before, a parade where the past doesn't get forgotten. You watch Raki design her own path forward while surrounded by the ghosts of everyone else's journey, and somehow that makes her story bigger, not smaller.
Raki Kiseki transfers to Star Harmony Academy with big dreams of becoming an idol, armed with a mysterious Aikatsu Pass her engineer sister gave her. When she activates it, reality bends in unexpected ways: doors materialize around her, each one opening onto encounters with legendary idols she's never met. These aren't just chance meetings. They're invitations to a hidden world where the biggest names in the idol industry move between stages and timelines, and Raki finds herself caught in the crossroads. Rather than follow the standard path to stardom, Raki decides to forge her own route. She'll design her own premium dress from scratch and perform in it on the biggest stage possible, refusing to walk someone else's carefully laid track. What starts as pure ambition becomes something deeper: a journey through the interconnected lives of idols who inspire her, each with their own stories and struggles. This is less about the competition and more about discovering what it means to create something truly your own while surrounded by people chasing similar dreams.
