In a world ruled by idols, Yuri rose to the top. Her charm unified the world, and she became the elected President. Upon her retirement, she chose six Excellent Idols as her successors. Mimu is a high school girl who wants nothing more than to be like Yuri, and sing in Crystal Hall.
Her dream brings her together with the six Excellent Idols, and they embark on a quest into the Tropical Dimension. This world is in peril, and it can only be saved by swimsuit contests, obstacle courses, mud wrestling and, of course, idol singing!
Mimu Emilton is a cute fourteen-year-old who has come to the annual Starland Festival to become an idol, just like her role model, Yuri. It is the most celebrated event on a united Earth, and Yuri, now the President of Earth, has encouraged people to join the ranks of Excellent Idols. Unfortunately for Mimu, she can never seem to make it to her audition on time, as misadventure after misadventure lands her in situations (usually involving undergarment exposure, I might add) that she escapes with the help of the current Excellent Idols, whom she befriends. Just as she makes her place on the stage and begins her audition, though, an unknown group of aliens kidnaps her and the Excellent Idols. It is only the beginning of a wild interdimensional goose-chase that places Mimu in the position to save the world, if only she can believe in herself.
In a world unlike our own, fourteen-year-old Mimu Emilton dreams of becoming an idol. Luckily for her, the search for a new idol is afoot in Starland! During the tryouts, however, she and several other famous idols are whisked away to another world where an intergalactic idol competition is taking place. What better chance for the earthlings to prove their idolness once and for all? With contests abounding and ecchi galore, Mimu certainly has her hands full… but can she become the most famous idol of them all?
