A magical squirrel pulls real idols into a world made of rainbows, and the movie doesn't apologize for the pure joy of it. The animation breathes with color and movement in ways that make you forget you're watching people perform versions of themselves. This is a love letter to the people who showed up for ten years, wrapped in the kind of visual spectacle that only happens when you stop trying to convince anyone this matters and just let it.
Five idols stand at a crossroads. After a decade together, i☆Ris has built something real, but doubt creeps in about what comes next. During a concert day, a mysterious white squirrel materializes in their dressing room with an urgent message: reality itself is fracturing. A flash of light transports the group to Risu Risu Land, a surreal dimension where wishes become tangible and limitations dissolve. Here, anything is possible. Dreams take physical form. The girls wander through this paradise, testing the boundaries of what they can become, what they can achieve without constraints. But something fundamental is missing. The world is silent. No melodies ring out. No voices blend in harmony. The squirrel reveals the devastating truth: music has vanished from existence, and only i☆Ris can restore it. What begins as a fantastical escape becomes a test of why they became idols in the first place. To save this impossible world, they must remember what makes them complete.
