Several years after the incident in Amazawa town, Chinami Ebihara is now a member of an organization - founded by Sonomi Kujo - called OZ. Like its rival Foundation, OZ studies those with the special power known as 'Type-E' - the ability to affect electrical devices. However, while OZ wishes to help Type-E users gain control of their powers and be productive members of society, Foundation wishes to gain their power through force and use them for unknown purposes. Along with a fellow Type-E user named Maori, Chinami goes on missions to determine Foundation's motives and protect other Type-E users from their grip.
Ryunosuke and his father are running away from his crazy mother when, feeling the urge to answer nature's call, Ryunosuke finds a cute little alley cat and decides to keep it. Almost immediately after, they are caught in a fire fight with his mother's lackeys. Tragically the poor cat dies and Ryunouske is heartbroken, but luckily his inventor father just happened to bring along a deactivated robot. By placing the cat's brain in the robot, Nuku Nuku is born! Now all they have to do is teach Nuku Nuku how to behave like a normal girl instead of a super-strong, cat-brained robot, while trying to avoid a mother's wrath!
Much to her delight and surprise, Haruka was selected to become an "idol." Little did she know what she was getting herself into; rather than singing and dancing, she actually is employed by a secret organization that protects the Earth from "drops" (falling fragments of the destroyed moon) using giant robots called "iDOL," piloted by girls called "iDOL Masters." As she meets new friends and tries to adjust to this new life, a hostile organization that also utilizes iDOL emerges and attacks her in an effort to capture her iDOL, Imber. Can Haruka accept her new responsibilities, get along with her new peers and Imber, and do her part to protect the world?
