A girl who forgot how to sing discovers a butterfly that moves like music looks. The pond it emerges from isn't a reset button or a wish machine; it's a mirror, and what Sora finds reflected there is the thing she lost before she lost her voice. This is a show about the moment you recognize yourself again in something small and glowing, moving through the world without permission or apology.

Sora once loved to sing, but something happened that left her afraid to sing in front of others, and over time she forgot how to sing and even how to laugh. One day she and her little brother Daichi come across a mysterious pond called Kagamiike, the Mirror Pond. There Sora spots a magical butterfly glowing in aurora colors and feels a connection to it. She reaches out, loses her balance and falls headfirst into the pond, and Daichi falls in too while trying to help her. Beyond the surface lies a world of wonder and mystery, where an odd girl named Rococo greets them. The three set out on an adventure through the Land of NOMO, and along the way Sora begins to confront the feelings she has kept hidden inside. The single ONA blends fantasy, adventure and mystery, and was made as part of the Panasonic Group Pavilion project for Expo 2025.
