Alcyone is the first antagonist the Magic Knights encounter, as she has been ordered by Zagato to destroy the three girls from another world so that the legend of the Magic Knights never comes true. She is a powerful adversary whose attacks and spells are ice-based. She has the ability to summon beasts from the spirit realm. Alcyone is the most loyal and arguably strongest of Zagato's followers, because she is motivated by love. However Zagato does not return her feelings and uses her loyalty rather heartlessly. In the second season of the anime, Alcyone returns under mysterious circumstances.
