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. On a concert day, a mysterious talking white squirrel pops out of a T-shirt delivered to their dressing room. A flash of light transports the group to Risu Risu Land, a surreal world where wishes become tangible and limitations dissolve. Here, anything is possible. The girls wander through this paradise, living out their dreams. But something fundamental is missing: there is no song anywhere in this world. The squirrel asks i☆Ris to help bring it back, and along the way the girls may discover who they truly want to become.
