Eastern Zodiac Keys

Eastern Zodiac Keys (東獣帯鍵, Tōjūtai Kagi) is a branch of Celestial Spirit Magic, which summons twelve Celestial Spirits, in a similar vein to the Golden Zodiac Keys. Much like the Golden Keys, they are rare, and considered invaluable, as well as exceptionally powerful spirits. Ironically, despite the name, Eastern Zodiacs don't use literal keys, instead using small jade figurines of their perspective animal that summons them onto the human world from the Celestial Spirit World.

 * The Eastern Zodiac Keys are based off the twelve chinese zodiac.
