G-On Riders

Japanese Title: G-on らいだーす

Chinese Title: G-on少女騎士團

Plot
In the near future, most of the Earth has been conquered by aliens. However, a small region in Japan has successfully repelled them thanks to the development of "G-On" technology by the Grand Rifurekuto Amudo/Grand Reflect Armored (GRA). This technology involves a band of girls (at first two, then three) who channel energy through special glasses. In this way they're able to destroy the giant mechanized monsters, "Fancy Beasts," sent by the aliens.
