In deep space a battle wages between the forces of good and evil and the fate of the Earth hangs in the balance. The evil Neos Gold dispatches her invading forces towards Earth with only one aim: the total destruction of all mankind. Now it's up to Iczer 3 (the younger sister of Iczer 1) to defend the Earth from the deadly armada of Neos Gold, with only the Earth's single remaining battle cruiser on her side. But don't count her out; what Iczer 3 lacks in experience she makes up for in all-out enthusiasm.

After the death of Saizou, Kabamaru's horribly strict grandfather and Iga ninja teacher (sensei), an old lady, Ran Ookubo, claims that she received a letter from him asking her to take care of his grandson.

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.
