Karyu

It is the peaceful Edo period in Japan, and ninjas are hardly needed anymore. Karyu, a particularly skilled ninja, is forced to do work as a hired killer. She is asked to kill a merchant, but when she gets there, she finds that his servant is actually a ninja, who is just as skilled as Karyu. Her name is Uzume. Karyu and Uzume then compete against eachother in a bloody battle for superiority. (Source: Anime News Network)
On Thalia's birthday, Salmacis, the Spirit of the Well, predicts that Thalia will first betray and then save the Meadowlands. When Thalia loses her necklace, the evil traitor Phaedon takes it to Lord Kann's fortress where it is filled with a poisonous liquid. Daiman unsuspectingly takes it back to Thalia. Menel, the leader of the fairy council, inadvertently unleashes the poison upon the sacred well. Salmacis vanishes, fulfilling the first part of the prophecy. Continued in Episode 2 "The Invasion".
