Galaxy Fraulein Yuna is a series of video games, anime, and other media from Japan. The Japanese title literally translates to "Galaxy Lady Legend Yuna".
The main character of the series is Kagurazaka Yuna, a somewhat ditzy 16-year old girl. After winning a "Galactic Bishōjo Contest", she becomes "Savior of the Lightside", a magical girl charged with defending the universe from evil. After becoming the "Savior of the Lightside", Yuna gains an impressively powerful armored suit, however, her greatest strength lies in her ability to befriend anyone, even her enemies. Her group of comrades (which is extensive) is comprised almost exclusively of former opponents.
