Break Blade (2014)

In the continent of Cruzon, an impending war between the Kingdom of Krishna and the nation of Athens is brimming. The people of this land are able to wield the crystals from the ground for whatever purpose they desire. Yet one person, Rygart Arrow, is not. He is an "un-sorcerer", a person unable to wield the crystals. But this characteristic will enable him to pilot an ancient mecha, one strong enough to put up a fight against the invading army of Athens.
