She is a celebrated member of the Empire until one day she finds out the shocking truth that she is a “Norma” – an irregular being who cannot use “Mana”, and who are treated as "things" rather than people. Having her name taken from her, Ange is isolated on Arzenal, a remote island. There, she finds a group of Norma women who spend their days huntingDRAGON's that have come to invade. ^[3]

Warning if you plan to watch this:
I don't really recomend this anime to someone that is faint hearted and easily influence. It has disturbing images, lot of sexual scenes, and has a dark story. But if you can handle it, then this might be an anime you might like. I enjoyed it, probably one of my favorite anime in 2014. 

Also might make a 2nd version b/c this is just her without the complete outfit.
