Mahou Shoujo Tokushusen Asuka
There is violence and death and blood and guns and torture. Yes I would say that this anime is a nice change of pace considering all the pretty cute outfits that come along with it.
So the story generally goes, evil magical creatures invade earth and then someone comes to the defense of earth and eventually saves the world. Well this is the story of what happens to those people after they are retired. Seems that things are not so simple when the government gets involved in producing the magical girls.
