All the girls once dreamed of becoming pop idols, and our principal female character is no exception. Someday they will become real stars! The anime series is about a girl – Haruka – who trips to Tokyo under the feeling that she was selected to become an idol after accompanying an audition. Nevertheless, upon coming in Tokyo, a Giant Mecha breaks out of the ground and, through the help of gravitational command, plops Haruka down in its cockpit.
After this event, Haruka learns that the company that she engaged is actually a multinational organization named Mondenkind, who is looking for a girl to pilot Giant Mechas – called iDOLS – in order to help protect the earth from falling meteors.
