At the Nerima Ward Ooizumi Academy Photonic District, the Robot Girls are selling "Photonic Energy', a new type of "cheap and green power." The lab's research has been going nowhere and their government funding's been cut off, so their finances are a mess. Just when the three robot girls are bored out of their minds, the part-timers they hired arrive. They are Garada-K7, with her long pigtails, and Doublas-M2, who only speaks with the two hand-puppets she wears. But they soon realize that the two have come to stop them from selling Photonic Energy, and a battle begins.—Crunchyroll
