Keta: The Last Black Dragon

In a normal late summer night, Keta, an ordinary eighteen-year-old girl, is abruptly ripped away from her life in her village. After surviving a rape, she discovers she possesses a tremendous and destructive power, a power that she cannot control, a power that can either save or destroy the world as we know it. Helped by Edward, a mysterious spearman with dark armour, and his brother Alexander, an herbalist with a strange past, she begins a journey seeking to learn how to control her magical power. She has no clue that to obtain such control will decide the fate of every single life on earth: to be saved or to suffer the Eternal Darkness.
