Intro. Cross Ange: Rondo of Angel and Dragon tells the story of Ange, a princess from a utopian world powered by magical energy called Mana, who discovers she is a "Norma" (unable to use Mana) and is exiled to a military base, Arzenal. There, she joins other marginalized women to pilot mechas (Ragna-mails) and fight dragons attacking their world, while uncovering a conspiracy about the true nature of Mana and her destiny as a rebel leader. Well, anyone who watched the anime knows it, and well, you're a Norma, as they say—no magic—and you're heading to the island of Arzenal where you'll live and have to stay forever. You can never return to the city again. But look on the bright side: the island is full of beautiful, sexy, and very tempting women. Although, well, some of them are fierce. And in the anime, you're just a soldier there to fight dragons from another dimension, alright? Enjoy.
