Cross Ange: Rondo of Angels and Dragons Lists

The series is set in a utopia generated through Mana. It focuses on first princess of the Misurugi Empire, Angelise Ikaruga Misurugi. She was celebrated by the people of the empire, and was supposed to wear the crown. However, the shocking truth is that she is a Norma: an irregular existence that cannot use Mana, and are treated as heretics and as "things" rather than people. She is exiled to a remote island where she instead meets a group of Norma girls who know nothing but battle. The girls spend their days riding humanoid robot weapons called "Para-mail" hunting giant DRAGONs that have come from another dimension to invade.
