Gou Non

Blue-haired and blue-skinned, Non is one of the most powerful sorcerers of the Witch-World. Non is Megu's main contender for the crown; a cold, alien being almost devoid of emotion. Setting a precedent for many later mahou shōjo anime, Non attempts to murder Megu during their very first meeting and continues to plague her throughout the series. Eventually, Non comes to admire her rival's innate courage, even joining forces with her against mutual enemies (such as the demonic witch-queen Saturn and her devious henchman, Chou-san) in several episodes. While true friendship is never an option, the two reach an uneasy truce by the middle of the series, agreeing to hold off their final confrontation (for possession of the throne) as long as possible.
