Galaxy Fräulein Yuna (1992)

Yuna Kagurazaka was just your ordinary high school girl in the year 2299 – a bit carefree and more than a little absent-minded, but nothing special… until she won the Galaxy Fräulein Contest and rocketed to idol stardom! But when her fellow contestants begin disappearing one by one only to turn up wearing power armor and trying to kill her, she discovers her true destiny: she is the Savior of Light, protector of the galaxy, and must fight to keep the forces of darkness from conquering the universe! Can Yuna take down the evil Thirteen Fräuleins of Darkness, or will hinging the fate of the cosmos on the whims of a flighty teenage girl prove a colossal mistake? … Possibly both.
